3M™ 480FR Industrial FR grade Silicone Adhesive Sealant
3M™ 480FR Industrial FR grade Silicone Adhesive Sealant is a rapid curing and low odor RTV adhesive sealant for use on a variety of applications. Especially, it can be used for fire stopping area in the many industrial fields ike construction, railcar, automotive, and shipbuilding because of its fire resistance property.
It is a flexible, non-corrosive(does not give off acid during/after cure) compound which has good adhesion to most of industrial aterials (clean metal, painted surfaces, wood, ceramic, glass, and many plastics including PC & PMMA). 3M™ 480FR Industrial FR grade Silicone Adhesive Sealant also has good resistance to bacteria, oils, aqueous anti-freeze agents and sea water.
