Membrane-vacuum adhesive Robust A-145

Glue for the production of cabinet furniture
Polyurethane adhesive dispersion for membrane-vacuum pressing. Suitable for molding PVC, PP, etc. films under the action of molding presses (with and without membrane) on wood-based relief parts. It is recommended to use with a hardener to increase heat resistance.

The scope of membrane-vacuum pressing is very wide: these are voluminous furniture facades made of MDF, and door leaves, and rounded tabletops, and various decorative elements of furniture. The lining of all these objects is carried out using a vacuum press (with or without a membrane). As a rule, PVC films with a thickness of 0.3-0.5 mm (rarely 0.25 mm) are used in production, plain, with a printed pattern, texture.
