EXTON, Pa.—AGC Chemicals Americas, Inc., a supplier of fluorochemical technologies and compounds, is offering two new polyols to enhance urethane adhesives and sealants that are critical for automotive applications.
Preminol, a polyether polyol, maintains a high molecular weight (from 3,000 to 18,000) and offers high flexibility, elongation, strength, durability and workability, according to AGC.
Excestar, a silane-modified polyether polyol, is produced from Preminol technology and has the benefits of Preminol, while also having a hydrolyzed silyl group on the end. Like Preminol, this liquid polymer also has high flexibility, in addition to heat and stain resistance, weatherability and paintability. Typically, AGC said this product can be used in construction, industrial and electronic applications, is toxic free and easy to use.
Both Preminol and Excestar improve the performance of urethanes so that they have better resistance to vibration, heat and UV light, demanding conditions that are part of the automotive environment.
The polyols are ideal for use in "adhesives and sealants used in structural bonding, headlight assembly, windows, interior and exterior trim, body and engine sealing, weather stripping, and more," AGC said in an Aug. 7 release.
Headquartered in Exton, AGC Chemicals Americas has manufacturing facilities in nearby Thorndale, Pa.; a satellite sales office in Sao Paulo, Brazil; and warehouses throughout North America.
