Obtaining patent protection on coating formulations can be a challenge when the coating formulation is a combination of existing (i.e., “old”) raw materials. However, as coating formulators are well aware, developing coatings by combining existing raw materials in a new way can lead to synergistic interactions and yield an unexpectedly improved coating. The manner in which a newly developed coating formulation is presented to the United States Patent and Trademark Office (USPTO) can be critical in determining whether a patent will ultimately be issued.
This presentation will detail the challenges of obtaining a patent on a coating formulation, including the USPTO’s typical rejections of patent applications directed at coating formulations. This presentation will also detail various strategies for obtaining a patent on a coating formulation with an emphasis on designing laboratory experiments and presenting experimental data to the USPTO. Finally, this presentation will also discuss the process of eventually compromising with the USPTO on a particular claim scope, and how strategically designed laboratory experiments have the potential to shape the compromise.

Over the years, a wide range of corrosion inhibitors has been studied to find suitable alternatives for hexavalent chromium to protect high strength aluminum alloys. Recently, lithium salts have been proposed and patented as a potential corrosion inhibitor in coatings. This work presents the use of lithium salts as potential corrosion inhibitor in coatings. Lithium carbonate and lithium oxalate salts were incorporated as pigments in model organic coatings and applied on aluminium alloys. It was found that the lithium species were able to leach from the coating and promote the formation of a protective layer on the alloy in the coating defect. The development of the protective properties of the layers has been studied with electrochemical techniques. The chemistry of the developed layers was studied using Microscopic and surface analytical techniques. The results demonstrate that lithium salts can represent a potential new class of corrosion inhibitors replacing hexavalent chromium in coatings for the protection of aluminum alloys.

No matter the size of the paint shop, dirt defects in paint coatings are virtually impossible to eliminate. One of the most effective ways to control dirt is through a comprehensive dirt program, which is outlined in Dirt Identification to Elimination (Subda 2005). This program outlines a seven step program and the step by step guidelines for execution of dirt elimination. A crucial step in this program is identifying the dirt so that the source, or multiple sources, can be identified and reduced or removed. Typically a microscope is the most efficient and practical way to handle dirt identification. From hand held to bench top models, there are a wide variety of microscopes that could assist with pinpointing a dirt source. Only after the dirt particle is identified as an environmental defect, like a bug or fiber, or an application defect, like paint spit or flocculated pigment, can the source begin to be controlled. Bench top microscopes that can be connected to a computer can also assist in building a dirt database that can be used to compare defects from various parts or lines. Various microscopes, additional equipment, and methods for sample preparation and utilization will be discussed. Other identification methods outside of microscopy will be touched on, including expected test results and explanations.

Dirt mitigation coatings are becoming increasingly attractive to diverse industries ranging from automotive to architectural to aerospace. In the automotive industry, clearcoats that are easier to clean and to keep clean are of value to both the OEM and the final consumer. PPG is developing a premium scratch-resistant 2K isocyanate clearcoat technology that resists adhesion of common environmental contaminants such as dirt, road tar, bug splatter, and pine sap. Using a variety of novel hydrophobic resins, excellent dirt mitigation performance has been demonstrated while still providing premium clearcoat attributes. Early prototypes have shown the ability to substantially alter the wetting characteristics of the clearcoat to promote dirt mitigation, but retention of the property in the field remains an intense area of focus. In order to improve the durability of the easy-to-clean properties during field exposure, a recent emphasis has been on understanding the surface chemistry and hydrophobicity balance as a function of clearcoat depth. Recent prototypes based on a combination of surface-active additives and proprietary hydrophobic binder systems are showing promise for extending easy-to-clean clearcoat functional lifetime.

Dirt, everybody has it, nobody wants it. Small shops with two people up to large shops with a hundred people have dirt in their coatings. With an infinite number of sources and a variety of shapes and sizes, dirt in paint is hard to control and nearly impossible to eliminate. Controlling and or eliminating dirt can only be accomplished through a comprehensive dirt program.
Learn what a comprehensive dirt program is comprised of and how to apply it. One methodology, that has been used successfully to identify and eliminate dirt, is covered in an easy to follow step by step format.

The automotive engineer must design a vehicle that meets an array of performance, safety and quality targets and that can also be produced robustly at volume, meet the needs of customers and deliver profit to the company. Increasingly stringent fuel economy requirements pose further challenges to the engineer but also the opportunity to apply new materials and technologies that might otherwise be considered “over-engineering”.
One strategy to enhance fuel economy performance is the use of materials that result in a lightweight vehicle body compared to traditional designs, exemplified by Ford Motor Company’s 2015 F-150 truck with all aluminum body. Although known for their passivating characteristics, aluminum and its alloys may form a galvanic corrosion cell with an adjoining dissimilar material and aluminum alloys themselves are susceptible to localized corrosion manifest as pitting and (in painted condition) blistering and/or filiform corrosion.
This presentation describes some of the new approaches adopted for laboratory assessment of lightweight materials’ corrosion performance. Cyclic corrosion tests are compared to filiform corrosion tests for scribed, painted aluminum. Electrochemical characteristics of aluminum alloys are compared to those of steel, magnesium and carbon fibre reinforced polymer. Experimental approaches to corrosion assessment for mixed material joints are described and initial results are presented.

In this presentation we describe the results of a study to balance coating performance and feel characteristics of polyurethanes used on automotive interior rigid plastic parts. Achieving a good balance of performance and soft feel can be difficult because of the seemingly divergent properties needed to achieve a rubbery polymer feel (low Tg) and chemical/scratch resistance properties (high crosslinking of the polymer). Further complicating coating development in this area is the subjective nature of feel when humans try to describe the interface between their finger and the polymer coating.
We used a Design of Experiment (DOE) approach to map haptic feel of polyurethane coated plastic substrates against key coating performance targets. The results yield a coating formulation space for hundreds of potential coating formulations and their predicted haptic feel rating overlaid with performance properties.
We conclude the discussion by presenting our attempt to quantify three different haptic ranges, and how this knowledge will impact the coating development. The initial coating feel ratings were obtained via survey of human subjects knowledgeable in soft feel coating applications. We then correlated this data with polymer physics analysis test data which included surface friction and micro-indenter measurements. Some correlation was observed which allows us to provide a quantification of feel and to give direction to the coatings development.

Chipping performance of body paint on a vehicle has become increasingly important in harsher climates such as North America and Russia. Stones can cause body paint to chip down to substrate and expose bare metal, which can then lead to corrosion. The primer layer serves not only as the adhesion promoter between metal substrate and topcoat, but also secures overall chipping performance of the coating system.
The benefits of a softer body primer have been established and described in Bock and Engbert’s SAE paper “Waterborne Polyurethane Based Paint Materials for the Automotive Industry – Present Situation and Future Possibilities,” however, the challenge exists in accommodating various application process conditions.
This paper describes the balancing of developing a robust high chipping performance body primer with lower glass transition temperature (Tg) and higher damping efficiency (tan delta), while maintaining critical process parameters such as reparability and indirect material compatibility performance.

The formulation of aqueous pigment dispersions can be a challenging and time consuming endeavor as the proprietary nature of additives and varied pigment surface chemistries limit a chemist’s ability to consistently apply theory and experience. Lifting the veil of ‘trade secret’ may be a losing effort for the formulator, but estimating additive performance and interactions based on general chemistry offers potential shortcuts and reductions in wasted lab time. Such shortcuts will be discussed in this paper through categorization of the common surface active chemistries utilized in aqueous pigment dispersion, discussion of formulating strategies to optimize performance based on empirical testing and observation, and a detailed approach that limits formulation dead-ends.

Polyester polyols containing TMCD (2,2,4,4-tetramethyl-1,3-cyclobutanediol) have shown unique physical properties that increase the overall performance of automotive coatings. A comparative study between traditional polyols used in automotive and industrial coating applications versus TMCD based polyesters is reported in this study. Some of the key performance attributes that were taken into consideration as a part of this investigation are weathering, mar resistance, Volatile Organic Compound (VOC) content and coating appearance. Our study has shown that TMCD based polyols exhibit significant enhancement in weathering with an improved abrasion resistance and solids content as compared with some of the commercial resins currently used in the market. Two accelerated weathering techniques were employed in combination with photo – oxidation value (POV) testing to fully demonstrate the improved weathering performance and determine that the photo degradation of the resins are significantly improved with TMCD based polymers. An aggressive UV integrating sphere accelerated weathering method that strongly correlates with the well-established SAE J2527 Xenon Arc method was also able to provide meaningful results 3–5 times faster to predict failure. TMCD-based polyester polyol resins have also shown good weathering in QUVB testing where traditional polyester resins do not.

Additive Manufacturing (AM) or 3D Printing (3DP) have become buzz words in new technology development for UV cure. Even though patents dating back to 1986 have shown the use of such processes recent interest has accelerated the use of this type of technology. A recent RADTECH conference brought forth the latest developments in UV technology oligomers and new equipment designs.
The paper will attempt to review the current state of the art on Additive Manufacturing and 3D Printing as it relates to the use of UV cure oligomers and monomers. This review will cover the positive aspects of using a thermoset technology vs the use of thermoplastics. In addition the paper will review proper UV oligomer polymer designs that will decrease the shrinkage levels that are currently being seen using traditional UV cure oligomers. These high shrinkage levels can be the Achilles heel for this technology.

The industrial coatings market in North America is continually looking for ways to introduce efficiency into the coating process. One way to achieve this is by the use of direct to metal (DTM) topcoats that do not require the use of a primer. The formulation of water based high gloss DTM topcoats requires the manipulation and optimization of many ingredients including: binders, coalescing agents, dispersing agents, thickeners, etc. In this paper we explain how the use of high throughput screening (a robot) aided in the optimization of a water based high gloss DTM topcoat formulation. The factors of the formula that were manipulated were dispersant agent level and coalescent agent combinations (seven ternary combinations). In total, we looked at 210 different formulation combinations. We tested for: color, gloss, salt spray, water and chemical resistance. Favorable formulation space was realized for the performance parameters tested.

In the recent years, organic-inorganic hybrid (OIH) coatings have emerged as very promising candidates for myriads of advanced applications. One of the most efficient routes for deriving such coatings is via sol-gel chemistry. Organo-silanes are among the most common starting materials (precursors) for making OIH coatings via sol-gel route. The most interesting and useful aspect of sol-gel derived coatings is our ability to manipulate coating microstructure at nano/micro scales, by use of suitable precursors and processing parameters.
This presentation will highlight some of our research work involving development of novel silane precursors and their applications in advanced coatings. Two families of silane precursors – epoxy-silane and bis-ureasil – have been prepared and used as primary components of OIH coatings. Chromate-free OIH pretreatments have been developed and studied for their corrosion resistance performance on aluminum alloy substrate. Such coatings, when incorporated with nano-silica particles and corrosion inhibitors in optimum amounts, outperformed chromate-based pretreatments that are currently used but targeted for replacement due to their high toxicity and environmental burden. In another study, we have designed and developed super hydrophobic coatings by leveraging the potential of sol-gel chemistry and nano-technology. By manipulating the surface energy and topography, super-hydrophobic coatings (water contact angle >140°) have been prepared. Our design strategy and key highlights of the study will be discussed.
