Silastic 1080 RTV Silicone Sealant is a one part, Neutral (Non
Acid) cure Silicone material of paste like consistency that
cures to a rubbery substrate when exposed to moisture in the
air. It is essentially recommended for corrosion sensitive
materials where acid - curing types of sealants cannot be
tolerated or where curing odours may be objectionable.
