| Product Name | Aluminum Foil Butyl Rubber Waterproofing Membrane |
| Material | Butyl |
| Color | Silver |
Butyl rubber waterproofing membrane is a single or double-sided self-adhesive membrane, mainly made of butyl rubber, and coated on reinforced or corrugated aluminum foil. This material bonds strongly to various surfaces, perfect for color steel tiles and roof cracks. It delivers excellent weather, aging, and waterproof resistance, effectively sealing the bonded surface. It also offers shock absorption and protection, staying in an uncured state during its service life, thus ensuring great adaptability to the thermal expansion, contraction, and mechanical deformation of the adhered surface. As a solvent-free product, it doesn't shrink or emit harmful gases, serving as an eco-friendly waterproof sealing and adhesive material.
