Target: The pre-applied method usually adopts the polymer self-adhesive film waterproofing membrane and thermoplastic polyolefin (TPO) pre-applied waterproofing membrane, which is composed of a layer of hot melt pressure sensitive adhesive layer and particle protection layer on a certain thickness of HDPE substrate or TPO. Hot melt pressure sensitive adhesive is mainly composed of synthetic rubber, resin, rubber oil and various additives, etc., mixed and heated into a molten state, with a certain anti-ultraviolet aging and bond sealing durability, and can reach molecular contact with concrete to form an effective bond, so as to achieve the effective fusion of membrane and post-cast structural concrete. However, due to the poor water resistance and weather resistance of hot-melt pressure-sensitive adhesive, some problems have been brought in construction applications. In order to solve the above problems, Kesun developed a series of pre-applied butyl polymer waterproofing membrane.
