With proper surface preparation this product offers superior adhesion to cured FRP parts. It is not recommended to
solvent-wash the bonded surfaces before application. End users should determine the suitability of this product to their
process. There can be issues with achieving a good bond to highly cured gel coat and gel coated parts. In cases
where the gel coat is over a month old, has been post-cured, or could otherwise be highly cured, the user should test
for adequate adhesion and may need to sand and clean the part before applying the adhesive material.
Application: PA-133-PMMN may be used for general bonding and to fill cracks, corners, and angles where
reinforcement is required. Surfaces to be bonded should be free of dust, waxes, oils, and mold release agents.
Sanding may be used to enhance adhesion as long as dust is completely removed. Cleaning surfaces with solvent is
not recommended.
Storage and Handling: PA-133-PMMN should be properly stored in closed, opaque containers at temperatures not
exceeding 77 F (25 C). Store only in original containers. To avoid decomposition keep away from direct sunlight and
excess heat. Refer to the Safety Data Sheet for further details on safety and storage.
