Strongsville, Ohio -- PPG Industries' commercial coatings group has introduced two high-hiding, yellow urethane resin bases intended to provide increased hiding power for select industrial colours.
These resins -- AUE-300YL and AUE-360YL -- join the AUE-300 (a low-volatile organic content urethane enamel) and AUE-360 (a high-solids urethane enamel topcoat), as part of PPG Commercial Performance Coatings' portfolio.
"AUE-300YL and AUE-360YL have been used to reformulate certain colours in the two-book PPG Commercial Performance Coatings colour selector," said Steve Podlas, PPG brand manager for commercial coatings, in a company statement.
"We identified 25 colours to date as having formulations that often take five or six coats to achieve hiding using the standard, clear mixing resin. But now, with AUE-300YL and AUE-360YL, we can provide 30 to 35 percent better hiding than the original formulation," added Podlas.
PPG explains that hiding, or hiding power, is the ability of a paint film to mask a colour or pattern on the surface the paint film covers. According to Podlas, the yellow colour of the new resins gives them enhanced hiding capability and in turn reduces the number of coats required. As a result, the end user gains lower labour and material costs.
"Better hiding means saving time and expense to the customer," Podlas added. "And obviously, that's a significant benefit."
AUE-300YL and AUE-360YL are recommended for interior and exterior use on properly prepared surfaces. Application examples include metal fabrication, castings, cabinets, machinery and heavy equipment. AUE-360YL offers excellent exterior durability, mar and chemical resistance, UV resistance, and high dry film hiding capability with minimal coats.
