PVC Upstand

Description

For bonding single-ply PVC roofing membranes

PVC Upstand Contact Adhesive is designed to fix single-ply PVC roofing blankets to upstands and roof detail work.

• High plasticiser resistance for good adhesion on up-stands 
• Applied by brush or roller 
• Apply using a 2-way dry stick OR heat activation 
• Withstands temperatures of -40°C to 70°C 
• Shelf-life of 12 months.

Applying with a 2-way dry stick

• First, clean both surfaces with solvent or abrade with a clean emery cloth 
• Apply an even film to both surfaces by brush or roller, using a coverage rate of approximately 1.5m2 Kg 0.75m2 of bonded area 
• Allow both films to dry for up to 10 minutes, or until they can be gently touched without any adhesive being transferred 
• Join the surfaces together, using as much pressure as possible to avoid trapping any air.

Applying with heat activation

• Apply the adhesive to both surfaces as above, and allow to dry completely. 
• Heat both surfaces to 100°C and use pressure to bond together immediately.
