Block Shape Butyl Sealant - Air Tightness and Electrical Insulation

Block shape butyl sealant is a kind of environmental friendly, non solidified self adhesive sealant. It can maintain its plastic and sealing properties without crack and harden in a wide temperature range. What's more, its excellent weather resistance, acid and alkali resistance, good air tightness and electrical insulation properties make it have good adhesion to glass, aluminum alloy, galvanized steel, stainless steel and other materials. And due to its extremely low water vapor transmission rate, block shape butyl sealant with elastic sealant together can form an excellent anti moisture system. Block shape butyl sealant is applicable for all kinds of machinery, pipe, glass installation, cable joints and other seals as well as buildings, water conservancy projects, etc.
