PPG PR-142 PRC Standard Spec Adhesion Promoter 1 oz – Ideal for Spot Repairs

PPG PR-142 in 1 oz glass bottle format provides the same high-performance adhesion promotion as the larger 16 oz format, in a convenient small package ideal for aircraft spot repairs, single-joint sealing operations, and field maintenance where minimal material usage is required. The 1 oz size minimizes material waste on small jobs and is easy to carry and use in confined aircraft maintenance areas.

Meeting PRC Standard Specification requirements, PR-142 enhances sealant adhesion on aluminum alloy and steel aircraft surfaces, ensuring reliable, long-term seal performance even in the 1 oz format. Its consistent formula quality matches the larger bottle variants, providing the same adhesion promotion chemistry in a field-friendly package size.

The small bottle format is particularly valuable for aircraft line maintenance operations, field repair teams, and MRO technicians who need a compact, lightweight adhesion promoter solution for on-aircraft sealing repairs.

Technical Information

The 1 oz format of PR-142 contains the identical adhesion promoter chemistry as the larger bottle variants, providing the same molecular coupling mechanism at the metal-sealant interface. The small package size does not affect the product’s performance or shelf life when stored per PPG’s recommended storage conditions.

For spot repair applications, the 1 oz bottle provides sufficient material to treat localized sealing areas without requiring the technician to manage a larger, partially-used container. The glass bottle construction ensures compatibility with the solvent-based promoter formulation and prevents any interaction between the container and the active ingredients.

Application technique for spot repairs should follow the same procedure as production applications — clean surface, apply thin uniform coat of PR-142, observe flash-off time, then apply sealant. Even for small repairs, proper surface preparation and adhesion promotion are essential for achieving specification-compliant, long-lasting seal performance.
