Usage Instructions
The strength and durability of the adhesive depend on proper surface preparation.
Clean the surfaces to be bonded, removing dust and grease.
For metal surfaces, remove any oxide layer until the clean metal is visible. For other materials, remove the old surface through sanding or grinding to create a rough, fresh surface. Painted surfaces must be completely free of paint.
Mix part A and part B according to the weight ratio in the table below:

Apply a sufficient amount of the mixture to both surfaces.
Hold the surfaces still until the adhesive cures.
