Adhesives/Sealants

Fast-Cure Silicone Adhesive

DESCRIPTION

Two-part, translucent, thixotropic, high tear strength silicone system
Cures 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
