Troubleshooting Bonding Problems

Most bonds for Mr. Sticky's^® Premium Adhesives are no problem. Should you experience low bond strength, the most likely difficulties are:

1. The materials aren't clean or roughened (generally clean with alcohol or acetone) to properly clean and roughen always: Step 1 - Clean, Step 2 - Roughen, Step 3 - Clean again.

2. The Materials are contaminated with Silicone residue or mold release from production. Mold releases are specifically designed to resist bonding. This prevents unwanted adhesion to foreign objects and promotes clean surfaces. Unfortunately, it also prevents bonding to epoxy. Try deep abrasion or cleaning with silicone remover.

3. The Plastic is a copolymer which includes significant amounts of Polyethylene, Polypropylene or Teflon. For Polyethylene use Poly-Bonder, following pre-treatment instructions. Poly-Bonder has moderate bonding capability with Polypropylene but no bonding to Teflon.

4. Plaster or tile has been coated with a silane or other type of sealer which resists bonding. Remove the sealer.

If the above does not take care of the problem and you can be more specific about the nature of the materials and application, contact us and we will try to help you further.
