A general purpose, exterior protective acrylic lacquer coating for metal surfaces. This coating is particularly formulated for resistance to diester lubricating oil and heat for the aircraft industry. Available in gloss, semigloss and lusterless finishes.
Chemsol’s MIL-PRF-81352C TY.III Polyurethane Coating is a two component chemically cured exterior coating that forms a film that is resistant to chemicals, solvents and abrasion. This product has excellent adhesion to most substrates and is recommended for heavy duty industrial applications where a tough, chemical resistant coating is required. This coating is available in a 4:1 mixture for brush, roll and spray applications. It is specially formulated for excellent ultraviolet ray resistance and superior exterior durability.
Surface must be clean, dry and free of all contamination before application of primer.
APPLICATION & REDUCTION
MIL-PRF-81352B Type I & MIL-PRF-81352C Type I Acrylic Lacquers can be applied by conventional or airless spray application. For spraying, thin up to 10% or as needed with MIL-T-81772B TY.3 Thinner. For brushing,reduce up to 10% with MIL-T-81772B TY.3 Thinner Brush small areas only.
SURFACE PREPARATION FOR MIL-PRF-81352C TY III
Surface to be coated must be clean, structurally sound and free of all foreign contaminants including dirt, wax, loose paint or grease. Greasy or oily surfaces should be solvent cleaned with care taken not to paint over moist or wet surfaces. The recommended primer is MIL-P-23377G or MIL-P-85582C applied at a dry film thickness of 0.6 – 0.9 mils.Old paint in peeling condition must be removed. Abrasive blasting is the preferred method. Chalky paint must also be wire brushed for maximum adhesion.
APPLICATION FOR MIL-PRF-81352C TY. III
Chemsol’s MIL-PRF-81352C TY.3 Polyurethane Coating can be brushed rolled or sprayed. Mechanically mix each component, then combine at a ratio of 4 part pigmented component to 1 part catalyst by volume. Let admixed material stand for 15 minutes before using to allow for chemical induction. If thinning is required, use Griggs MIL-T-81772B Type I Polyurethane Thinner. Apply at a dry film thickness of 1.7 – 2.3 mils.
