Contact glues remain really elastic after bonding (that is what makes the bond very durable). They contain solvents, are especially good for planar bonds on diverse materials and should be used as follows: apply the adhesive evenly to both sides – in the case of larger areas use a SERRATED SCRAPER for application – allow it to evaporate for approximately 15 minutes until the glue is no longer sticky to the touch and then firmly press the pieces together. In doing this last step, it is the amount of pressure applied, not how long you apply it, that determines the solidity of the bond. Repositioning is not possible.
Pattex Classic high-strength glue is a solvent containing contact adhesive that provides the highest bond strength, is water resistant and very resistant to heat. Pattex is especially good for bonding wood materials with laminates, rubber, leather, cork, felt, rigid PVC, soft foam, metal and much more. Pattex is not suitable for use with PE and PP or polystyrene foams, soft-PVC or synthetic leather. Pattex high-strength glue should be applied to both sides of the pieces to be bonded. Before joining the pieces together, the solvent must be allowed to evaporate (at room temperature this takes about 15 minutes). The pieces should then be pressed together firmly for a short time. The initial adhesive strength is so high that the workpiece can be further worked on immediately after the joint has been made. After about 3 days, Pattex achieves its maximum bonding strength. It takes between 250 and 350 grams to bond one square metre when applied properly (to both sides of the bond).
