Sky New Materials Butyl Adhesive EPDM membrane SK-W-A

Butyl adhesive EPDM membrane(SK-W-A)is made of EPDM membrane with one-side compound butyl rubber adhesive layer.Aftercompounding.the membrane that can be directly bonded to the building structure firmly In application practice,the butyl rubber adhesive can react with the concrete or cement,and then firmly combine with the base.Italso has good ability to fil the crack,which can effectively solve the ‘water flowing”problems.

Application:

EPDM waterproof membrane is a fully vulcanized rubber membrane synthesized from ethylene-propylene diene terpolymer. Appropriate amounts of reinforcing agents, fillers, vulcanizing agents, accelerators, softeners, etc. are added during production. It is processed through internal mixing, filtration, extrusion molding and other processes. After compounding the butyl rubber self-adhesive layer, a waterproof membrane that can be directly bonded to the building structure is formed.

Recommended Applications: Flat Roof;Pitched Roof;Window
