Laur Silicone L-580

Laur Silicone L-580 offers outstanding thermal stability. It was designed to offer high heat transfer without compromising heat stability. The Laur L-5XX series is intended for use with a post cure. Long autoclave cure cycles often used in the roller industry may enable the cured silicone to not require a post-cure. Sheet stock should be post cured. The material is designed to be self- bonding. However, in most applications the use of a primer will improve bond pertormance.
