Foam can create many problems in manufacturing, application, and performance of waterborne paints and coatings. Therefore, defoaming additives are included in formulations to prevent or eliminate foam and its associated problems. Although defoamers can have positive effects on the performance of a coating, use of a defoamer that is not suited for the specific formulation and application can cause even greater problems. Furthermore, identifying the optimal defoamer for a given application can be time consuming and complex because of the multitude of factors that affect defoamer performance. Defoamer performance is controlled by the chemistry and formulation of the additive, as well as many formulation, application and manufacturing variables such as type of agitation, application method, coating ingredients and chemistry, pigment volume concentration, coating viscosity, application thickness, and drying time. However, it is possible to predict a defoamer’s performance in different types of coatings and applications based on its chemistry and formulation. This paper will discuss how the design of defoamers can affect performance in coating formulations and provide examples of how these designed defoamers can be utilized to select an optimal defoamer for coating formulations and applications.

Novel Rheology Control Agents (RCA) that are acrylic based crosslinked nano size materials were developed. They provide unique characteristics of offering low viscosity but highly effective rheology control for balancing flow and leveling. These materials have well defined surfaces and functionalities. The mechanism of RCA performance is its thixotropic behavior during film drying/curing process. These materials do not exhibit thixotropy in the nascent form but as the solvent evaporates during film formation networking takes place due to dispersion force and donor-acceptor interactions. This causes a favorable increase in viscosity to control the excessive flow especially in thicker films where sagging can take place and from sharp edges where the material can be pulled away leading to poor or no edge coverage.
The utility of RCA for sag resistance and edge coverage, while maintaining good appearance were established from creep compliance, sag tests, cross sectional microscopy, and wave scans. Compliance values measured with a Rheometer were indicative of cumulative film flow and showed good correlations with sag resistance. Balanced flow was achieved for good sag resistance/edge coverage and appearance. In this paper we also intend to present a mechanistic insight and performance results in comparison to some commercial products.

The pre-treatment layer is an important component of a multi-layer coating systems used in metal finishing. This thin conversion coating applied directly onto the bare metal is intended to enhance the corrosion resistance and adhesion of the primer coat. Due to environmental and toxicity concerns, the industry is looking for alternative systems that can replace those containing toxic substances. Organic-inorganic hybrid conversion coatings derived from sol-gel chemistry have been found very promising to meet these challenges and have been commercialized in recent years. This presentation will discuss some fundamental aspects of sol-gel chemistry, hybrid conversion coatings and their suitability for industrial applications. Highlights of our research on developing epoxy bis-silane based hybrid pretreatment technology for automotive aluminum alloy, and results of electrochemical (EIS and DC Polarization study) corrosion resistance measurements, in conjunction with accelerated salt-spray tests will be discussed.

The perceived quality of an automotive paint finish—especially during the first several minutes—is linked to an emotional reaction not easily explained by the customer. Paint quality metrics linked to this perceived quality reaction are not externally available. For this reason, an internal competitive benchmarking survey was established over 10 years ago to capture these metrics using validated tools, and to globally benchmark them across OEM’s, brands, models, and paint technologies. One actionable paint quality metric that is relatively new on the scene is mottle, an undesirable blotchiness or striping defect which is most obvious on light metallic finishes. The new toolbox instrument that quantifies mottle has been used in these competitive benchmarking studies, as well as during process optimization studies for launches and new equipment. Initial results have indicated that this tool provides potential actionable trends and may be valuable for process development.

Increasingly stringent automotive fuel economy regulations will lead to changes in the way vehicles are designed, powered, manufactured, and used. One approach to improving vehicle fuel economy is to radically reduce vehicles’ weight through the use of lower density, higher strength materials. However, most of the potential lightweight materials bring challenges associated with integration into current vehicle manufacturing processes as well as potentially higher costs. High strength steel, aluminum, magnesium, and carbon fiber/polymer composites will all play roles in future lightweight vehicles, particularly if vehicles are designed up-front to capitalize on the materials’ beneficial properties, as opposed to simple materials substitution. The benefits and drawbacks of each lightweight material will be discussed along with the impact vehicle lightweighting may have on automotive painting.

Automotive parts producers are increasingly interested in UV curable coatings for their aesthetic, performance and processing benefits. For example, water clear, durable topcoats are used in a variety of interior and exterior trim applications. Today, even UV powder coated plastic parts such as decorative wheel trim are being produced.
The highly cross linked nature of UV composition compared with conventional formulations, along with the fact that many UV cure materials contain no solvents to wet out the part surface, often result in challenges to obtain adequate adhesion.
This paper presents research on the use of atmospheric plasma surface treatment to mitigate problems with adhesion of UV compositions to a range of plastic substrates. We demonstrate that plasma treatment prior to application of UV liquid and powder coatings may provide an attractive alternative to using more costly substrate, the use of adhesion promoters, or other means of enhancing adhesion.
This technology may enable the use of UV materials including UV powder on a broader range of substrate than previously possible, opening up new coating applications for automotive designers and manufacturers.
This paper compares the performance properties of two types of low gloss (matte) polyurethane clearcoat formulations with an eye towards automotive refinish applications. A two-component solvent-based clearcoat formulation (with flattening agents) is compared against a unique two-component water-based clearcoat formulation that does not require flattening agents to achieve low gloss. This comparison study tested for pendulum hardness, pot life, dry time, gloss retention and color change in xenon arc accelerated weathering. The data suggests that the two-component waterborne polyurethane coating formulated without flattening agents exhibits better performance with regards to gloss retention, i.e., maintains a consistent low gloss, than commercially available solvent-based polyurethane clearcoats employing flattening agents. Additionally, the two component waterborne polyurethane clearcoat formulation shows somewhat better burnish resistance. While more work remains before use in automotive refinish applications is endorsed, further work is warranted based on the initial results.

Presented here are 1 side weigh strip weigh coating weight measurement methods that use less toxic chemicals and are as easy as the traditional chromate methods. These methods can generate standards to calibrate XRF coating weight instruments, using less toxic chemicals and as easy as the traditional chromate methods but far safer. Iron phosphate on cold rolled steel and zinc phosphate coating on hot dip galvanized, aluminum, cold rolled steel and even electrogalvanized steel can be stripped without etching the metal substrate.
XRF instruments for measurement of phosphate coating weights have many significant advantages over other techniques.
The primary standard for measurement of coating weights on phosphate metal is the weight strip weigh method, now easily usable as a one-side method with safer chemicals. Standards can be generated for calibration of other XRF instruments.

Over the last decade the automotive refinish industry has been forced to look at new technologies which reduce volatile organic content (VOCs) and hazardous air pollutants (HAPs) while providing a rapid return to service of the consumer’s vehicles. UV A cured 1 K auto refinish primers were first introduced in the middle 1990’s. UV A Clear Coats were subsequently introduced in the late 1990’s. Materials have continued to be developed and pushed to mimic the classic 2K solvent based polyurethanes (PURs). However, slow acceptance by the auto refinish market over the last decade is indicative of a market that is difficult to change. RADTECH in conjunction I-CAR, an industrial training organization for the collision repair professional, developed a web based training module for UV A Cure 1 K auto refinishing. Since 2008 this paid web training module from I-CAR has had over 900 courses purchased by the collision repair professional.
This paper will review the past history of the UV A cured 1K auto refinish market and formulations for primers and clear coats. It will also attempt to look at current UV A cured 1K auto refinish primers and clear coats in the NAFTA market as well as new formulations and new developments in UVA equipment.
