Different Types Of Glue For Wood Lamination

When it comes to wood lamination, the laminating term can apply three different procedures. The fist in the wood laminating is the woodworkers use to glue wooden planks together to create a wide wooden surface like a tabletop. The second one is that they apply glue on the surface of wooden layers. The last in the laminating procedure is for adding a thin veneer covering or plastic covering to the flat existing surface. For instance, in paper extrusion coating laminating machine for paper lamination also need glue especially in hot rolled lamination. The following are some types of glues described which are used in wood lamination.

Polyurethane Glue:

The Polyurethane Glue is also advertised as the strongest glue. The wood breaks before either the glue bond fails. However, the polyurethane glue is used in laminating wood. This lamination requires the use of the clamp. This glue is waterproof and can also use for exterior laminations.

Polyvinyl Acetate (PVA):

The polyvinyl acetate is also commonly known as carpenter’s glue which means is it mainly used for wooden purposes. Combined strong in water as well, there are two color tones available in these materials. The white glue is a good multipurpose domestic adhesive, whereas the yellow variety is stronger than the other. The bond by this glue is tougher than the wood itself. As it has a long open time, here the “open time” refers to the time in which the glue remains in liquid form and workable. You should use clamps to hold the wood while the process of lamination. Then you need to wait for the polyvinyl acetate glue to dry. Generally, polyvinyl acetate glue comes in plastic bottles with tapered caps on the top. This makes the glue easy to apply on the edges of the wood.

Urea-formaldehyde:

Woodworkers need a good-quality glue when they are laminating curved wood. The glue is urea-formaldehyde which does not stretch or pull away from the edges of the wood. They are also known as plastic resin. The open time of urea-formaldehyde is similar to the polyvinyl acetate, so the wood must clamp. This glue can fill the gaps and bond those areas where uneven pressure is applied.
