Adhesives/Sealants

Fast-Cure Silicone Adhesive

DESCRIPTION
  • Two-part, translucent, thixotropic, high tear strength silicone system
  • Cures at room temperature and rapidly with the application of heat in an oven, or by a heat gun or lamp
  • Many bonding applications do not require the use of a silicone primer for suitable adhesion
  • Does not require atmospheric moisture to cure
  • No curing byproducts such as acetic acid or methyl alcohol
  • Consistency allows product to be supplied in easy-to-use, airless side-by-side kits that eliminate mixing and deairing difficulties
  • 1:1 Mix Ratio (Part A:Part B)
APPLICATION
  • Adhesive for bonding and sealing silicones to each other and other substrates such as metals and plastics
  • For rapid production or prototyping due to a rapid cure
