Current automotive coatings systems consist of several layers, such as an adhesion-promoting layer, primer, basecoat and clearcoat.

Today’s coatings market expects more from its white pigments than brightness and opacity. White pigments, such as titanium dioxide (TiO2), barium sulfate (BaSO4) and zinc sulphide, are just examples of many ingredients possible in a complex coatings formulation.

In Part 1 of this article series,1 we discussed a new class of reactive surfactants, both nonionic and anionic, for use in both conventional aqueous emulsion polymers and in UV-curable coatings that contain two polymerizable moieties.

The trade-off in the yellow and orange color space between the weatherability, heat stability and opacity of inorganic pigments versus the chromaticity, brightness and tint strength of organic colorants, in light of the decrease in use of pigments based on deprecated metals, has opened an opportunity for new colored pigment chemistries.

Acrolon Ultra is a high-gloss, solvent-based acrylic polyurethane providing long-term UV protection for high-profile structures where high durability is required.

NANOMYTE® TC‐3001is a new flexible coating specifically designed to protect oxidizing steel and aluminum exposed to corrosive chemicals or harsh environmental conditions.

Ultrashield is a new line of interior/exterior, high-performance coatings.

A full line of Teflon® powder coatings that are electro-statically applied to pumps, mixers, tanks, valves, and other components is available.

PURALACT® special-grade lactides provide reduced resin viscosity, allowing for coatings formulations with higher solid content, lower VOCs and improved ease-of-use.

This article reports on the performance results of acrylated monomers and oligomers when subjected to typical end-use tests designed to measure the flexibility and adhesion characteristics of coatings.
