AGC Chemicals Americas
EXTON, Pa., August 7, 2020 – Adhesives and sealants used in automotive applications must perform reliably to meet strict production standards and ensure the safety of the end users. To address this challenge, AGC Chemicals Americas offers PREMINOL™ ultra-high molecular weight polyether polyol and EXCESTAR™ silane-modified polyether polymer. Both polyols impart performance properties like high strength and elasticity so that the urethanes can better withstand demanding automotive applications that require improved resistance to conditions such as vibration, heat and UV light.
AGC uses a unique synthesis technology and polymerization process to achieve high purity and high molecular weight. This enables PREMINOL and EXCESTAR polyols to cure faster and improve functionality of end products.
PREMINOL and EXCESTAR add high-performance properties like tensile strength, durability, elongation, elasticity and mechanical strength. This makes them 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.
PREMINOL has ultra-low monol content, ultra-high molecular weight ranging from 3,000-18,000, and a narrow molecular weight distribution. This provides good mechanical properties such as high flexibility, elongation, strength, durability and workability (via faster skinning time and low viscosity).
EXCESTAR is a silane modified polyether polymer that imparts unique properties to sealants and adhesives such as high flexibility, heat resistance, weatherability, paintability and stain resistance. EXCESTAR products are toxic-free and easy to use. Because it is based on PREMINOL technology, EXCESTAR incorporates these benefits while adding value by having hydrolyzed silyl group on the end.
