APPLICATION INSTRUCTIONS

• All surfaces must be clean, dry, dust and grease free. Best result will be achieved with surfaces that have been lightly abraded immediatelyprior to bonding.
• If using accelerator apply to one component surfaceonly. Apply thin film of adhesive to the other surface and bring the pieces together immediately. Hold for few seconds without disturbing the joints.
• When bonding “O” rings, cut a fresh surface onto each end of the rubber to gain the best possible strength.
