Membrane Pressing – The Principle

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 and placed in a membrane or vacuum press which heats the foil, applies vacuum for decompression, applies pressure and reactivates the glue line. The result is a door panel that is produced much faster than a lacquered solid wood or painted door, with a vinyl covering that is easy to clean and durable. As this type of production has become more popular over the years, foils are now extremely authentic with realistic wood effects and matt and high gloss finishes emulating a typical painted product. These foils have in turn put more demands on the membrane press adhesives to create the perfect finish.

Chemique Adhesives for Membrane Pressing – The Protak Range

For gluing PVC foils with membrane and vacuum presses, polyurethane based dispersion adhesives are used due to their high thixotropic nature, good sprayability, optimum reactivation and high speed of curing. To improve the heat resistance of these adhesives it is necessary to use an isocyanate hardener in either encapsulated form for single component grades, or separately for two component products. Chemique have an extensive range of both one and two component adhesives for membrane pressing.

Protak Adhesive Range – Grades and Characteristics

As with all bonding applications, there is not one glue that meets all the demands of each panel producer, and therefore Chemique have developed a wide range with individual characteristics, taking into consideration cost, export demands, type of press, ease of use and performance on more demanding foils such as high gloss, and avoiding the ‘orange peel effect’.

The Range

A comprehensive range is offered of both one and two component options with a variety of viscosities, in either neutral or blue colours, with or without fluorescent tracer. All Protak membrane press adhesives give excellent spray characteristics, uniform surface finish, high bond strength and high heat resistance.
