Adhesives/Sealants

Extremely Tough High Durometer Fast-Cure Adhesive/Sealant

DESCRIPTION

Two-part, gray silicone adhesive system
Cures at room temperature or rapidly by applying heat in an oven or by a heat gun or lamp
Does not require atmospheric moisture to cure
No curing byproducts such as acetic acid or methyl alcohol
Product available 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
