Supermarine Zinc-Plate Primer (SM-1757) provides powerful zinc protection! A very fast-drying zinc rich primer designed primarily as a corrosion-inhibiting product for use on aluminum boats or marine equipment, ferrous and nonferrous metal surfaces in marine environments. Use it alone or apply a marine finish coat over it. A premium-grade, high solid marine primer that not only acts as an effective rust preventative on steel and iron substrates but should be viewed as an integral component of any corrosion resistant coating system.
Zinc-Plate is yellow zinc rich and contains a balanced composition of special pigments and phenolic modified resin providing good rust-inhibitive properties and blister resistance for better adhesion and metal protection. It is satisfactory for application in a wide range of temperatures and humidity conditions. Conforms to government specification number TT-P-1757. Color: Yellow. Product type: Zinc Chromate Phenolic Modified Alkyd Rust-Inhibitive Zinc Primer.
• Hard to find government spec formula.
• Fast drying.
• Zinc rich anti-corrosion formula.
• Binds rust to metal sealing out air and moisture.
• Promotes adhesion on hard to coat surfaces.
• Creates a firm base for virtually any top coating system.
Stats: Dry to the touch: 5-10 minutes, tack free: 20 minutes, time to recoat: 30 minutes, dry hard: 30 minutes. Weight Solids: 58-60%. Practical coverage is 300-350 square feet per gallon @ approximately 2.0 mils dry.
Recommended preparation: For best results remove old marine coating, loose scale, grease, oil and contaminates. Sand, grind, bead blast or power-wash prior to the application of any cleaner or primer. Where rust is evident use SM-5679 Phos-Pro Rust Converting Cleaner. All surfaces must be thoroughly clean and dry before the application of any marine primer, boat paint or antifouling bottom paint.
Application: This product is at a spray viscosity designed for airless use: The zinc primer should be allowed to dry a minimum of 1/2 hour before recoating with subsequent zinc primers or marine paints. It should be applied to a dry film thickness between 0.3-0.4 mil. For non-marine equipment, or on iron or steel surfaces it should be applied to 0.6-0.8 mil dry film. NOTE: This zinc primer is designed for spray application over surface-treated metal or pretreatment coatings (See SM-117 Pre-Treatment Wash Primer). If used for dip or flow-coat application, the product suitability should be determined by the user. Physical characteristics: Viscosity: 20-25 sec. #2 Zahn. Stir thoroughly before use. Brush, roller, or spray.
Thin & clean up: Use only with factory recommended thinner. It should not be thinned unless absolutely necessary. Thin if necessary with SM-605 Synthetic Thinner. Tools and equipment may be cleaned with SM-605 Synthetic Thinner
Shipping: Ships within 2-4 days of order.
