I am finding problem with solvent based adhesive. There is satisfactory adhesion between plywood and plywood. I am looking for improvement in adherance between plywood and laminate. Problem is on laminate side even after use of coupling agent. There is no wetting or poor coupling on laminate side after couple of days. Can someone suggest me suitable wetting agent/tackifier etc.
Hello Chandrashekhar,
As you know deciding on the right tacktifier depend on its molecular weight and polarity which determine the tacktifier solubility in the base polymer, having said that I think you may look for products suitable/compatible to your base polymer. for e.g. if base polymer is polar, then an aromatic product may suits better while an aliphatic is better for nonpolar.
I would recommend plasma treatment of the surfaces. The adhesion will be improved.
