What is Vacuum Adhesive or Membrane Adhesive? In recent generations, vacuum or membrane adhesive is a water-based adhesive to produce MDF with opaque and glossy PVC coating with flat press. It is used for the production of grooved, convex and curved MDF sheets using a vacuum machine and is marketed as one and two
Membrane Press Adhesive Membrane and vacuum presses are used to produce vinyl wrapped doors, which are an alternative to real wood or painted doors. A moulded and sometimes routed MDF core is sprayed with a polyurethane dispersion adhesive and allowed to dry. The panel, with dried adhesive is then covered with a PVC foil

Polyurethane Polyurethane (PUR and PU) is a polymer composed of organic units joined by carbamate (urethane) links. While most polyurethanes are thermosetting polymers that do not melt when heated, thermoplastic polyurethanes are also available. Polyurethane polymers are traditionally and most commonly formed by reacting a di- or triisocyanate with a polyol. Since polyurethanes contain two types of monomers, which polymerise one after the other, they are classed as alternating copolymers.
