Form This specification establishes requirements for a heat resistant aluminized organic coating with sufficient corrosion and erosion resistance for the finished substrate. Application The coating material covered by this specification is typically applied to the exterior of aluminum nacelle inlet lipskins of aircraft. It is suitable for use in a service temperature range from -65 to +600 ??(-54 to +316 ?? where this maximum temperature is on an intermittent basis. It is intended to have an appearance visually similar to sulfuric acid anodized aluminum. The liquid coating is suitable for spray application with high volume low pressure (HVLP) paint spray equipment.
