EXTON, Pa., August 24, 2020 – Adhesives used in electronics assemblies must perform without fail to protect delicate components from vibration and heat. They must also be able to secure the components without interfering with the operation of the end product. To address these challenges, AGC Chemicals Americas offers PREMINOL™ ultra-high molecular weight polyether polyol and EXCESTAR™ silane-modified polyether polymer to enhance properties of multi-material and pressure sensitive adhesive formulations.
AGC uses a unique synthesis technology and polymerization process to achieve high purity and high molecular weight with multiple functional groups. This enables PREMINOL and EXCESTAR polyols to achieve high strength and high elongation that improve the functionality of end products.
PREMINOL and EXCESTAR add high-performance properties like tensile strength, durability, elongation, elasticity, mechanical strength and temperature resistance. This makes them ideal for adhesives used in circuit boards, smartphones, tablets and other electronics.
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, faster curing time and primerless adherence. 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.
