International Intergard 405
International Intergard 405 is a two component epoxy sealer coat, pigmented with micaceous iron oxide. Formulated on proprietary polymer technology, which provides rapid cure and overcoating, even at low temperatures.
Best Uses
International Intergard 405 is formulated to provide efficient sealing of zinc silicate primers in order to prevent pin-holing of subsequent topcoats. Can also be used for sealing zinc and aluminium metal spray either as a single coat system or prior to overcoating with a suitable topcoat where required.
Intergard 405 is suitable for use as part of a coating system in a range of highly corrosive environments, including offshore structures, petrochemical and chemical plants, bridges, refineries, pulp and paper plants and power stations.
Application
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.
Primed Surfaces
Intergard 405 should always be applied over a recommended anti-corrosive coating scheme. The primer surface should be dry and free from all contamination and Intergard 405 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 Intergard 405.
Metallic Zinc Primed Surfaces
In the case of zinc primers, where necessary, remove weld spatter, smooth weld seams and sharp edges and blast clean welds and damaged primer to Sa2½ (ISO 8501-1:2007) or SSPC-SP6. The shop primer or other primer surface should be dry and free of all contamination (oil, grease, salt etc) and overcoated with Intergard 405 within the overcoating intervals specified for the primer (consult the relevant product data sheet). Ensure that the zinc primer has fully cured and is clean, dry and free from zinc salts prior to overcoating.
Apply using Airless Spray, Air Spray, Brush or Roller.
