Instructions for use

Check that the joints fit well. Apply adhesive evenly on one side. Assemble and press the parts together aiming at an even squeeze out for the whole length of the joint. The joints can be pressed in a hot or high frequency press. The final strength and water resistance of the bond is reached within 7 days.

With some wood types the adhesive’s acidity may cause discolouration in the adhesive bond. If in contact with iron, some discolouration in the adhesive bond may also occur.

NOTE! Kestokol D 320 HF is not suitable for cold pressing. Kestokol D 320 HF adhesive reacts even with a small amount of urea formaldehyde adhesive (1 %) forming a thick sponge. For this reason the application equipment (pump, hoses, roller) need to be washed very carefully prior to using Kestokol D 320 HF adhesive.
