www.us- tech.com AGC Formulates Additives for Enhancing Electronics Mfg. Adhesives


EXTON, PA —Adhesives used in elec- tronics assemblies must perform without fail to protect delicate compo- nents from vibration and heat. They must also be able to secure the compo- nents, without interfering with the operation of the end product. To address these challenges,


AGC Chemicals Americas is now of- fering PREMINOL™ ultra-high mo- lecular weight polyether polyol and EXCESTAR™ silane-modified poly- ether polymer to enhance properties of multi-material and pressure-sensi-


tive adhesive formulations. AGC uses a unique synthesis


technology and polymerization process to achieve high purity and high molec- ular weight with multiple functional groups. This enables PREMINOL and EXCESTAR polyols to achieve high strength and high elongation. PREMINOL and EXCESTAR


add high-performance properties, such as tensile strength, durability, elongation, elasticity, mechanical strength, and temperature resist- ance. This makes them excellent for


adhesives used in circuit boards, smartphones, tablets, and other elec- tronics. PREMINOL has ultra-low


monol content, ultra-high molecular weight ranging from 3,000 to 18,000, and a narrow molecular weight dis- tribution. This provides good me- chanical properties that include high flexibility, elongation, strength, durability, and workability. EXCESTAR is a silane modified


polyether polymer that imparts unique properties to sealants and ad-


hesives, such as high flexibility, heat resistance, weatherability, faster curing time, and primer-less adher- ence. EXCESTAR products are free of toxins and easy to use. Since it is

AGC’s additives are designed to enhance adhesives.


based on PREMINOL technology, EXCESTAR incorporates these bene- fits, while adding value by having a


hydrolyzed silyl group on its end. Contact: AGC Chemicals Ameri- cas, Inc., 55 E Uwchlan Avenue,

Emil Otto Expands Line of GSP Fluxes


ELTVILLE, GERMANY — The GSP flux series has been an important part of Emil Otto’s product portfolio for several decades and is one of the company’s best-selling products. The new GSP fluxes, 2633/RX and 2933/RX, as well as the respective OVAP versions, are alcohol-based, no-clean fluxes. The fluxes consist of a di-car-


boxylic acid activator complex and synthetic resin. All fluxes are versa- tile and were developed for selective and wave soldering, as well as for dip
