Heavy anti-corrosion epoxy zinc rich primer for steel structure bridge beams

Description :

　　Composition: A two-component coating composed of epoxy resin, zinc powder slurry, and curing agent.

　　Features: This paint has strong anti rust performance, cathodic protection, can penetrate into welding joints, is resistant to solvent corrosion, stable weather resistance under sunlight, and is prone to precipitation. The construction process requires high standards.

　　Purpose:Epoxy zinc rich primerSuitable for rust prevention on steel surfaces, underwater metal surface coating in the shipbuilding industry, and chemical anti-corrosion metal base coating.

　　Construction reference and precautions:

　　1. The surface is first sandblasted to remove rust, oil stains, and other impurities, and then coated with this paint.

　　2. When used for construction, mix component one and component two evenly in a 9:1 ratio, let them sit for 20-30 minutes before use, and continuously stir during use to ensure consistent composition.

　　3. According to the construction needs, adjust the viscosity to the appropriate level with diluent for better spraying effect.

　　4. The interval between two coats should be 24-48 hours, and the next coat should be applied after drying. The thickness of the two coats of paint film should be 20-30 μ m.

　　5. Construction is not suitable on humid or rainy days.

　　6. The storage period is one year. If the paint quality test is qualified and there is no significant change after the expiration date, it can still be used.

　　Main features:

　　1. Has cathodic protection function and excellent rust prevention performance

　　2. Excellent adhesion on sandblasted steel

　　3. Has good welding performance

　　4. Has good water resistance, oil resistance, and solvent resistance

　　5. Fast drying and good construction performance

　　Construction reference:

　　1. The surface of the coated object must be free of oxide scale, rust, oil stains, etc.

　　2. The substrate temperature must be at least 3 ℃ higher than the dew point. When the substrate temperature is below 5 ℃, the paint film will not solidify, so it is not suitable for construction.

　　3. After opening the bucket of component A, it must be stirred evenly. Then, pour component B into component A according to the mixing ratio requirements, mix thoroughly and evenly, let it stand for 30 minutes, and add an appropriate amount of diluent to adjust the construction viscosity.

　　4. Use up within 6 hours after mixing the paint.

　　5. Brushing, air spraying, and rolling coating are all acceptable.

　　6. Continuous stirring is necessary during the painting process to prevent sedimentation.
