YY-902 is a kind of polymer-modified asphalt and synthetic rubber as the base material, adding activating agent, using polyester tire as reinforcing layer, polyethylene film as surface material, and silicone oil anti-adhesive isolation paper on the bottom surface. Membrane, waterproof membrane with environmentally friendly and cold construction work.
Product Features
l Excellent waterproof performance;
l Excellent high temperature resistance and low temperature flexibility;
l Strong puncture resistance;
l The base layer has strong adhesion and good adhesion to a variety of substrates, and can lock the leakage caused by the damage of the coil to a local extent, thereby effectively preventing drowning;
l Good stability, good chemical corrosion resistance, easy construction, pressure sensitive bonding, long-lasting and stable waterproof effect.
Scope of application
All kinds of non-exposed underground works, roofing works, subways, tunnels, pools and other parts of the waterproof and moisture-proof works.
Construction process
Base treatment--elastic positioning--pre-rolling membrane--laying membrane--rolling exhaust--sealing head--quality acceptance--protective layer construction
