Tnemec Company Inc. (Kansas City, Mo.) introduced two low-VOC hybrid polyurethane finishes, reported to offer a high degree of color and gloss retention and resistance to UV and weathering.
The Series 740 UVX with gloss finish and Series 750 UVX semigloss formula are polyfunctional hybrid urethanes formulated with VOC content of 92 grams per liter—compliant with air-quality regulations throughout the U.S. and Canada, the company says.
Mark Thomas, vice president of marketing, said the products offer superior gloss retention and film hardness and similar color retention compared to standard aliphatic polyurethanes and polysiloxanes. The products also can be mixed using an inexpensive thinner, and offer ease of application using brushes, rollers, or spray equipment, he said.
When spray-applied, the coatings can deliver up to 6 mils dry film thickness (DFT) per coat. Cure time and handling characteristics are described as similar to existing acrylic urethanes.
Thomas said the coatings are based on a “unique blend of high-quality polyurethane resin, UV absorbers, and specialty additives.” The VOC content meets green-building requirements under Leadership in Energy and Environmental Design New Construction (LEED-NC) EQ 4.2, he added.
The company said the Series 740 version has been used on a number of projects across the U.S., with applications at industrial sites, water tanks, hydropillars, and standpipes.
