Instructions for use

Add 15 weight parts of Hardener WR into 100 weight parts of Kestokol WR 11 adhesive and stir well. If the pot-life of the mixture is exceeded, the mixture starts to foam. New mixture can be added into an older mixture within the pot-life.

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. Joints can be pressed in a cold, hot or high frequency press. In order to determine the necessary pressing time and ensure the adhesive joint strength, adequate tests are to be carried out before use in full-scale production.

Parts may need to be stored for a while before further machining to reach the necessary bond strength. The final strength and water resistance of the bond is reached within 7 days.
