International Interfine 691 is designed as a finish coat for use in both new construction and industrial maintenance. For use in a wide variety of aggressive environments including offshore structures, petrochemical facilities, bridges, pulp and paper mills, and power plants. Suitable for both site and factory application situations and is ideal where legislation prevents the use of isocyanates.
International Interfine 691 offers equivalent performance to typical recoatable polyurethane cosmetic finishes.
All surfaces to be coated should be clean, dry and free from contamination. Prior to paint application all surfaces should be assessed and treated in accordance with ISO 8504:2000.
Interfine 691 should always be applied over a recommended anti-corrosive coating scheme. The primer surface should be dry and free from all contamination and Interfine 691 must be applied within the overcoating intervals specified (consult the relevant product data sheet). Areas of breakdown, damage etc., should be prepared to the specified standard (e.g. Sa2½ (ISO 8501-1:2007) or SSPC-SP6, Abrasive Blasting, or SSPC-SP11, Power Tool Cleaning) and patch primed prior to the application of Interfine 691.
Material is supplied in two containers as a unit. Always mix a complete unit in the proportions supplied. Once the unit has been mixed it must be used within the working pot life specified. Apply using Airless Spray, Conventional Spray, Brush or Roller.
