Hot Melt Adhesive for Waterproof Membranes

Home - Products - Hot Melt Adhesive for Waterproofing Membrane

Hot melt adhesive is widely used in waterproof membrane applications because of its strong bonding performance, moisture resistance, flexible adhesive structure, and solvent-free processing advantages. Different formulations can support roofing membranes, underground waterproofing systems, flooring membranes, breathable waterproof materials, and construction sealing applications.

1. Membrane Lamination

Hot melt adhesives are used to bond multiple layers of waterproofing membranes together, enhancing their strength and durability.

2. Roof Waterproofing

HMAs are used to adhere waterproofing membranes to roof surfaces, providing a seamless and watertight barrier. This application is critical for flat roofs, green roofs, and industrial roofing systems.

3. Adhesive Seams and Joints

Hot melt adhesives are used to seal seams and joints in waterproofing membranes, ensuring a continuous and watertight barrier. This is essential for large-scale installations.

Hot Melt Adhesive Types for Waterproof Membranes

Pressure Sensitive Hot Melt Adhesive: Pressure sensitive hot melt adhesive is widely used in self-adhesive waterproof membrane systems because of its strong tack and easy installation performance.

PUR Hot Melt Adhesive: PUR hot melt adhesive provides strong moisture resistance, flexible bonding, and durable waterproof performance for membrane lamination applications.

Bitumen Hot Melt Adhesive: Bitumen-based hot melt adhesive is commonly used in roofing waterproof systems, podium decks, terraces, and underground waterproofing projects.

EVA Hot Melt Adhesive: EVA hot melt adhesive supports general waterproof membrane bonding and industrial lamination applications with stable processing performance.
