Sherwin-Williams Adds Acrolon Ultra
to Polyurethane Portfolio

Sherwin-Williams Protective and Marine Coatings launched Acrolon Ultra, a high gloss, solvent-based acrylic polyurethane providing long-term UV protection for high profile structures where high durability is required.

Acrolon Ultra provides excellent hiding and film formation at low film thicknesses (2-3 mils DFT), offering a distinct cost advantage during application, according to the firm. It is suitable for use in USDA-inspected facilities. The product complements Sherwin-Williams’ polyurethane portfolio by offering a solvent-based alternative to WB Acrolon 100, a high performance water-based polyurethane introduced in 2008. At less than 340 g/L VOC, it complies with current Ozone Transport Commission (OTC) limits.

Acrolon Ultra is optimized for brush and roll application and can be sprayed using airless or conventional spray equipment. It also provides a rapid return to service; the coating can be dry to the touch in as few as two hours after application. It can be shaded to virtually any color through the company’s 4,000 com-pany-owned facilities worldwide.

insulation (CUI) coatings to the oil and gas industry, Heat-Flex Hi-Temp 1200, an immersion-grade single-component inert multipolymeric matrix coatings. Rigorous protocols based on ASTM standards, conducted at the Sherwin-Williams labs where the first CUI coating was pioneered in 1999, documented better corrosion and abrasion resistance, and increased flexibility and harder film, the company reported.

Heat-Flex Hi-Temp 1200 combines ease of application, ambient cure, surface tolerance and UV resistance in one formulation for application under calcium silicate and mineral wool insulation systems, and is recommended for use in wet/dry cyclic service at operating surface temperatures of cryogenic to 1.200˚ F, with application temperatures from ambient to 500˚ F.

PPG introduces new
waterborne primers

PPG has launched two new waterborne primer surfacers, Envirobase High Performance EPW115 Waterborne Speed Prime and Aquabase Plus P950-5505 Waterborne Primer Surfacer, for the automotive refinish industry.

The low-VOC products are intended for use with PPG’s popular Envirobase High Performance and Nexa Autocolor Aquabase Plus waterborne product lines and will become essential elements in PPG’s waterborne refinish systems for collision repair centers across North America.

Both products offer direct-to-metal performance and may be applied over properly prepared substrates including cold rolled steel, aluminum and galvanized metals, plastic, E-coat, OEM or previously repaired refinish paints. Each air dries quickly and is ready to sand in 30 minutes. In addition, the fast air dry properties will reduce energy costs. EPW115 and P950-5505 both have a 24-hour pot life and are currently available in gray, with black and white options available soon. CW
