PPG Desothane CA800/I2881 USMC Medium Gray Aerospace Topcoat – Gallon Kit

PPG Aerospace Desothane CA800/I2881 is a U.S. Marine Corps (USMC) standard specification medium gray aerospace polyurethane topcoat from PPG’s Desothane product line — one of the most trusted brands of military aerospace topcoats in global military aviation. The I2881 color designation indicates the specific medium gray color shade approved under USMC’s aircraft paint specification, used on USMC fixed-wing and rotary-wing aircraft receiving standard gray tactical paint schemes.

Desothane CA800 is a two-component aliphatic polyurethane topcoat system providing the outstanding UV stability, chemical resistance, flexibility, and weathering durability that the Desothane brand has delivered to military aviation for decades. The CA800 chemistry meets the most demanding military aerospace topcoat specifications while providing excellent spray application characteristics, film-build efficiency, and the consistent batch-to-batch color and gloss reproducibility required for military aircraft painting operations.

The gallon kit is the standard production format for military aircraft painting operations — providing sufficient material for painting significant surface areas of USMC aircraft in a single maintenance event. The gallon format minimizes mixing operations compared to smaller kits, improving painting efficiency during large aircraft repainting operations.

Technical Information

Desothane CA800 uses an aliphatic isocyanate hardener reacted with a hydroxyl-functional polyol base to produce a high-performance aliphatic polyurethane coating with exceptional UV stability, color retention, and gloss durability. The aliphatic isocyanate chemistry provides inherent UV resistance — the polymer backbone absorbs UV radiation without the photodegradation that causes chalking and fading in aromatic isocyanate and epoxy coating systems. This UV stability ensures the USMC gray color remains consistent and within specification throughout extended outdoor service in all climates.

The I2881 color is a specific, reproducible medium gray formulated to the USMC’s approved color standard. Batch-to-batch color consistency is controlled through PPG’s manufacturing quality system to ensure that all Desothane CA800/I2881 production lots match the approved color standard within the tolerances specified in the USMC painting specification — critical for maintaining a consistent appearance across aircraft painted at different times and locations.

Application requires qualified spray equipment, appropriate environmental conditions, and film thickness measurement per the USMC technical order for the specific aircraft being painted. Consult the PPG Desothane CA800 application guide and applicable USMC technical order for full application procedure.
