HIGH TEMPERATURE ADHESIVES
EPOXIBOND - High Temperature Adhesives are designed for high performance applications in electronics/microelectronics and other industries. They cure fast at moderately elevated temperatures. The cured systems provide excellent bond to metals such as ferrite and beryllium and retain the bond strength even at higher temperatures. The fully cured products have excellent dielectric properties, and very good thermal shock & impact resistance. They also have good resistance to weather, water, most petroleum products, mild acids & alkalis, and many other chemicals.
