PPG PR-1523-M PRC Standard Adhesion Promoter 2 oz – Compact for Spot Repairs

PPG PR-1523-M in 2 oz bottle format provides the same metal-optimized, PRC Standard Specification adhesion promotion performance as the larger 8 oz format, in a compact size ideal for aircraft spot repairs, isolated sealing joint maintenance, and field repair operations where carrying and managing a larger container is impractical.

The 2 oz format is particularly valuable for line maintenance technicians and field repair teams who need a small, lightweight adhesion promoter that can be carried easily to the aircraft and used for a single sealant repair without the waste of opening a larger bottle for a minimal-material job. The compact bottle also reduces the risk of material exceeding its pot life after opening for small repair quantities.

PR-1523-M’s metal-optimized coupling agent formula ensures maximum sealant adhesion is achieved even on the small repair area, providing the same specification-compliant adhesion promotion as the production-size packages in a field-friendly format.

Technical Information

The 2 oz format of PR-1523-M contains the same metal-optimized coupling agent chemistry as the 8 oz variant, providing identical specification-compliant adhesion promotion performance on aluminum, titanium, steel, and composite surfaces. The small package size ensures the material remains fresh and fully reactive throughout its use period, as the shorter time between bottle opening and depletion reduces the opportunity for solvent evaporation or atmospheric moisture contact to degrade the promoter quality.

For spot repair applications, the entire 2 oz bottle may be used across multiple small repairs during a single maintenance event, or reserved for a single critical joint where maximum adhesion performance is required. The small bottle format reduces the risk of using aged, partially-depleted promoter material that may have reduced effectiveness compared to freshly opened material.

Field repair applications should follow the same surface preparation and promoter application procedures as production operations — proper cleaning, deoxidizing, and conversion coating before PR-1523-M application are essential for achieving specification-compliant adhesion even on small repair areas. Refer to the applicable Aircraft Maintenance Manual (AMM) and PPG PR-1523-M technical data sheet for the required surface preparation sequence at your specific repair location.

Frequently Asked Questions

Q: What is the MPN for PR-1523-M 2oz?
A: MPN is 1523M000XCA002BT.

Q: Is the 2oz PR-1523-M the same product as the 8oz version?
A: Yes. Both contain identical PR-1523-M chemistry and provide the same PRC Standard Specification adhesion promotion performance. The only difference is package size.

Q: How much area can 2 oz of PR-1523-M treat?
A: Coverage depends on application method and film thickness. Refer to the PPG PR-1523-M TDS for coverage rate guidance at the recommended application thickness.

Q: Is PR-1523-M 2oz suitable for fuel tank spot repairs?
A: Yes. PR-1523-M is formulated for fuel tank sealing applications on metal aircraft structures. Follow the Aircraft Maintenance Manual and PR-1523-M TDS requirements for fuel tank sealing surface preparation and promoter application.

Q: What is the shelf life of PR-1523-M 2oz after opening?
A: Refer to the PPG PR-1523-M TDS for open pot life and shelf life guidance. Store per PPG’s recommendations to maximize product life both before and after opening.
