Two-component epoxy intermediate paint polyamide adduct cured, good barrier and anticorrosion properties, good resistant to water, oil, chemicals, long recoating property
Features
Because of a large amount of flaky mica iron oxide included, it forms a "labyrinth" effect in the paint film, so the paint film has excellent barrier and corrosion resistance.
Excellent resistance to chemical atmosphere, industrial atmosphere and marine atmosphere, and has good resistance to seawater, salt, weak acid and weak alkali. Long recoating intervals.
Recommended use
1.Used as the intermediate layer and sealing coating of anti-rust paints such as epoxy zinc-rich primer and inorganic zinc-rich primer to enhance the barrier and protective properties of the entire coating.
2.Used as an antirust primer for steel structures.
3.Used as an interlayer in the coating system for concrete protection.
4.Used as a repair topcoat over old coatings where compatibility permits.
Application Instructions
Steel: blast cleaned to Sa2.5 (ISO8501-1) or minimum SSPC SP-6, blasting profile Rz30μm~75μm (ISO8503-1) or power tool cleaned to minimum ISO-St3.0/SSPC SP3
Pre-coated workshop primer: Welds, firework calibration and damage should be blasting cleaned to Sa2.5 (ISO8501-1), or power tool cleaned to St3.0.
Surface with coated primer: Clean and dry without zinc salts and dirt.
Touch up: Thoroughly remove the grease on the surface and clean off salt and other dirt. It is best to use blast cleaning to remove rust and other loose materials. Use power tool to polish the area of rust, and recoat this material.
Applicable and Curing
1.Ambient environment temperature should be from minus 5℃ to 35℃, the relative air humidity should not be more than 80%.
2.Substrate temperature during application and curing should be 3℃ above dew point.
3.Outdoor application is prohibited in severe weather such as rain, fog, snow, strong wind and heavy dust.
Applications
● Ambient environment temperature should be from minus 5℃ to 38℃, the relative air humidity should not be more than 85%.
● Substrate temperature during application and curing should be 3℃ above dew point.
● Outdoor application is prohibited in severe weather such as rain, fog, snow, strong wind and heavy dust.
● When the Ambient environment temperature is -5~5℃, low temperature curing products should be used or other measures should be taken to ensure the normal curing of the paint film.
