1. Description
Butyl sealant is a one-component neutral sealant based on butyl rubber suit for sealing the gap between metal or metal and other materials. it is the best choice for waterproofing, since the butyl rubber has strong penetrability control. It is mainly used for sealing of containers, refrigerated wagons, doors and windows, roof seals and expansion joints, and peripheral joints. It can form a film on the surface of the surface during the surface drying process thus make it become the best waterproof sealant. The sealant is neutral, so it has no corrosive effect to the board.
2. Application
It applies to all kinds of seams, holes and cracks in steel roofs. Butyl Sealant has a perfect tolerance on structure strains which results from tough weather such as strong winds, flood and storming, which often accounts for natural siphonage, i.e. leakage.
