What is a membrane adhesive? EPDM and textile membrane bonding

Membrane adhesives bond EPDM waterproofing membranes, façade and window membranes, or functional textile membranes permanently and tightly. Types and application.

"Membrane adhesive" covers two fields: bonding EPDM waterproofing membranes in construction and laminating breathable functional membranes in textiles. Both need a flexible, durable, sealed bond.

Construction (EPDM)

Typically MS/hybrid or SMX polymer based, solvent-free, adhering to concrete, brick, wood, metal and PVC, elastic after cure. Clean the substrate, apply in beads or with a notched trowel, place the membrane within the open time and roll it down.

Textiles

Breathable PTFE/PU membranes are bonded mostly with PUR reactive hot melts applied by gravure roller, spray or dots at very low coat weights to keep breathability and wash resistance.
