Contact Adhesive - For Two-Sided Bonding
Already applied contact adhesive today?
The most common purpose for contact adhesives is the connection of two non-absorbent surfaces or the bonding of surface materials, such as HPL, onto wooden materials. Another area of application is the coating of mouldings. The excellent functional strength directly after pressing allows for quick further processing.
Contact adhesives first need to be applied on both parts that are to be bonded. Particularly when using solvent-based adhesives, it is vital that both parts have enough time to air-dry, so that the solvents evaporate. The result can be checked by applying the so-called finger test: If you put a finger onto the glued surface and are able to withdraw it without pulling strings or even getting stuck, the parts can be pressed. The adhesive can be applied either by using an appropriate tank under pressure, manually with a putty or with a spray gun.
Advantage spray application
The application via a pressure tank or spray gun means an enormous temporal and economical advantage. The wide stream makes it possible to apply the adhesive quickly and efficiently onto big surfaces. Moreover, less glue is needed, as it is easier to control the amount that is applied.

Sprayable contact adhesive (Webspray) for direct application without the need for additional spray equipment. For the bonding on both sides of many different materials: rubber, carpet, leather, cork, felt, fabric, foam, chipboard, plywood, lightweight boards, MDF, OSB boards, PVC plinths, stairs and other smooth, non-porous surfaces.
After the adhesive has been able to air-dry, both adhesive films have to be put together. It is important to work very precisely, as a connection is formed immediately, even when applying short, sufficiently high pressure. This is the special advantage of contact adhesives: Due to the immediate strength, they are ideally suited for mouldings or to bond HPL edgings onto curves. Additionally, contact adhesives can be used to coat big, non-absorbent surfaces without long pressing times. This will save time as well as money.
