Epoxy compound exhibits superior thermal shock resistance

Wed, 10/20/2010 - 7:21am

INSULGEL 70 CC FR NS is an epoxy compound which exhibits superior thermal shock resistance. By making use of an inherently flexible epoxy resin and special filler technology, INSULGEL 70 CC FR NS provides reduced shrinkage and low coefficient of thermal expansion. This results in decreased stress and improved adhesion. In addition, a significant portion of the product is manufactured from environmentally sustainable raw materials.
