Adhesives should be applied uniformly along the phenolic
backer as well as the substrate the laminate is going
to be applied to. Adhesive should never be applied to
only one select area. It is important that uniform pressure
should be applied. Different types of glue can be applied
depending on the press and the board used.
Below, we list certain indications for the most common
types of glues and methods of application. However, these
are very generic and can be influenced by a variety of
factors.
It is always better to consult the supplier of glue to obtain
the precise and personalized parameters.
