Performance Characteristics

Color : Various Federal 595B colors
Product/Rex Number : N40 Series

Type II, Class 2, color 26270 Haze Gray, N40A400, meets the Low Solar Absorption (LSA) requirements.

Low Solar Absorption (LSA) Coating minimizes sun Heat Efficiency Transfer (HET). It was developed for marine vessels and/or other structures where a durable Haze Gray, Semi-Gloss, Silicone Alkyd is required that will minimize HET into the interior of ships and/or structures.
Type II, Class 2, color 26270 Haze Gray, N40A500, meets the Low Solar Absorption (LSA) and Rust Stain Resistance (RSR) requirements on the outboard discharge areas.

Low Solar Absorption (LSA)/Rust Stain Resistance (RSR) Coating minimizes the rapid formation of rust stain on marine vessels and other structures, especially at water discharge locations. Prevention of rust staining may be extended by washing discharge locations with low pressure fresh water (50lb/in²) to remove adherent rust.
