AC Tech 137 Adhesion Promoter (Clear)

For maximum adhesion, clean surfaces with appropriate solvent (reclaimed solvents should not be used) to remove dirt, grease and processing oils just prior to application. Use approved cheesecloth, or equivalent, that is free of oil and soap. Always turn cloth frequently to prevent contamination. Always pour solvent on the cloth to avoid contaminating the solvent supply.

Clean only a small area at a time, quickly wiping it dry with another clean cloth. Turn cloth frequently, before the solvent evaporates, to prevent redeposition of oil, wax or other contaminants.

Application Instructions

AC-137 Clear may be applied to solvent-cleaned surfaces with a clean brush or gauze. Excess should be wiped off while still wet with clean gauze sponges. Wait atleast 15 minutes before applying sealant. Surface preparation and adhesion promoter application procedure should be repeated if sealant is not applied within four hours.
