PPG DesoGel EAP-9 Clear BMS 10-128 Conversion Coating and Adhesion Promoter – Pint Kit

PPG Aerospace DesoGel EAP-9 is also available in the pint kit format for maintenance-scale surface preparation operations where the gallon kit would provide significantly more material than required. The pint is the preferred format for line maintenance painting, small repair zone surface preparation, and MRO operations where only a small area of aluminum structure requires conversion coating and adhesion promotion before spot prime and paint repair.

The pint format reduces material waste for maintenance operations where small treatment areas do not justify opening a full gallon kit. It also simplifies material tracking and hazardous material inventory for maintenance facilities that perform infrequent painting operations — the pint provides sufficient material for several small treatment operations without the inventory burden of the larger gallon container.

The same BMS 10-128 Type I, Class A qualified formulation as the gallon kit is provided in the pint — ensuring that maintenance repairs performed with the pint kit achieve the same specification-compliant surface preparation as production painting operations using the gallon. Using BMS-qualified material for maintenance repairs is essential for maintaining the aircraft’s corrosion protection system in certified airworthy condition.

Technical Information

DesoGel EAP-9 pint uses the same chromate conversion coating and adhesion promoter chemistry as the gallon kit — the same contact time, treatment procedure, and specification performance apply for both container sizes. The pint size requires careful measurement of the small quantity dispensed to ensure uniform surface coverage — particularly important with a clear product where visual coverage confirmation is challenging compared to opaque chromate conversion coatings that provide visible color change on treated surfaces.

For spot repair surface preparation, mask the repair area to define the treatment zone, apply DesoGel EAP-9 by swab or brush to the cleaned aluminum surface, maintain the required wet contact time per the PPG product data sheet, and rinse (if required) before the surface dries. Prime the treated area as soon as practical after treatment to minimize re-contamination of the prepared surface before primer is applied.

The pint kit should be stored sealed in a cool, dry location. Chromate conversion coating products have limited shelf life after opening — use within the shelf life specified on the container and discard opened containers that exceed the opened shelf life, as degraded product may not provide adequate conversion coating performance.

Applications

DesoGel EAP-9 pint is used for spot repair surface preparation, scribe mark treatment, mechanical damage repair zone treatment, and small-area aluminum surface preparation before primer on Boeing commercial aircraft in line and base maintenance operations.

Frequently Asked Questions

Q: What is PPG DesoGel EAP-9 pint?
A: The pint is a maintenance-scale format of DesoGel EAP-9 BMS 10-128 qualified conversion coating and adhesion promoter — ideal for small repair zones, line maintenance painting, and low-volume surface preparation operations.

Q: MPN for DesoGel EAP-9 pint?
A: MPN is EDEAP-9XX8BMP22K.

Q: Is the pint the same formula as the gallon?
A: Yes. Both pint and gallon of DesoGel EAP-9 are the same BMS 10-128 Type I, Class A qualified formulation — only the container size differs.

Q: Why choose pint over gallon for maintenance?
A: The pint reduces material waste for small repair areas, simplifies hazardous material inventory, and is preferred for infrequent painting operations where a gallon exceeds the treatment area requirements.

Q: How long is DesoGel EAP-9 effective after opening?
A: Shelf life after opening is limited. Use within the opened shelf life specified on the container label. Discard degraded product — inadequate conversion coating provides insufficient corrosion protection.
