Product Applications:
Industrial Protection: Widely used for protective coating on surfaces of industrial equipment, machinery manufacturing, and metal structural components such as chemical processing equipment, mining machinery, machine tools, and steel bridges. Effectively prevents metal corrosion and extends equipment service life.
Automotive Sector: Suitable for coating automotive components including chassis, drive shafts, and shock absorbers. Provides excellent corrosion resistance and wear protection, shielding vehicle parts from harsh environmental conditions.
Elevator Industry: Suitable for coating elevator trusses, traction machines, and other elevator components. It meets aesthetic requirements while ensuring long-term protective performance.
General Insulation: Can serve as a general insulation coating for metal surfaces requiring certain insulation properties. It provides protection while offering some insulation effectiveness.
Addition Rate:
This product is a single-component formulation typically requiring no additional special ingredients for direct use. To fine-tune specific coating properties—such as adjusting viscosity or improving leveling—appropriate additives may be incorporated under professional guidance. Additive quantities are determined by specific product and application needs. For example, thickeners are typically added at 0.1%-1% (by weight), while flow agents are generally added at 0.05%-0.5% (by weight). Always conduct small-scale trials before adding any additives to ensure appropriate dosages and avoid adverse effects on overall coating performance.
Usage Instructions:
Surface Preparation: Thoroughly clean the metal surface to be coated, removing grease, rust, dust, and other contaminants to ensure paint film adhesion. Surface preparation methods include mechanical grinding, sandblasting, or chemical cleaning, achieving a minimum standard of Sa2 or St2 grade. For old coatings with minor rust reappearance or untreated rusted surfaces, apply a multi-purpose rust-inhibiting primer as a base coat. Stirring: Thoroughly stir the product before use to ensure uniform consistency. As minor sedimentation may occur, stirring stabilizes product performance.
Application Methods: Multiple application techniques are available, including brushing, rolling, and spraying. When brushing or rolling, ensure even coating coverage to prevent sagging or missed areas. For spraying, use a dedicated spray gun, adjusting pressure and distance to achieve a uniform, smooth film. Adjust application parameters (e.g., paint viscosity, temperature, humidity) based on actual conditions during application.
Drying Conditions: This product cures at ambient temperatures or can be accelerated by baking. For ambient air drying, drying time is significantly affected by environmental temperature and humidity. Application is recommended at temperatures ≥10°C and humidity ≤75% RH. For oven drying, select appropriate temperature and duration based on specific requirements. Generally, baking at 80°C for 30 minutes or 120°C for 30 minutes is recommended. Specific conditions may be adjusted according to actual film thickness and performance requirements. During baking, ensure uniform oven temperature to prevent localized overheating or underheating.
Recoat Interval: If recoating is required, determine the recoat time based on the dryness of the previous coat and actual conditions. Under ambient air-drying conditions: - At 10°C: ≥24 hours - At 20°C: ≥12 hours - At 30°C: ≥4 hours Under oven-drying conditions, recoat intervals may be appropriately shortened, but ensure complete drying and curing of the previous coat before recoating.
Product Packaging:
50KG/drum. Store in a cool, dry, well-ventilated warehouse, avoiding direct sunlight and high temperatures. Optimal storage temperature is 5°C-35°C. Temperatures below 5°C may cause freezing and affect product performance; temperatures above 35°C may accelerate aging. Keep away from fire sources, heat sources, and strong oxidizing agents to prevent fire or other safety incidents.
Frequently Asked Questions:
Slow paint film drying: Possible causes include low ambient temperature, high humidity, or excessive paint film thickness. Solutions include raising the application temperature above 10°C, reducing humidity below 75% RH, or adjusting film thickness to avoid applying overly thick coats in a single application.
Bubbles in the paint film: This may occur due to excessive air incorporation during mixing, excessive spray gun pressure during application, or contaminants like oil on the substrate surface. Solutions include allowing the paint to settle for a period after mixing to release bubbles naturally; adjusting the spray gun pressure to an appropriate range; and ensuring the substrate surface is clean and free of oil or impurities.
Poor paint film adhesion: This may result from inadequate surface preparation, incompatibility between primer and topcoat, or issues during application. Solutions include: enhancing surface preparation to meet specified standards; selecting compatible primer and topcoat systems; and strictly adhering to application procedures while controlling parameters.
Product sedimentation: Minor sedimentation may occur during prolonged storage, which is normal. Thoroughly mix before use to restore normal consistency without affecting performance. Severe sedimentation indicates improper storage conditions or expired shelf life. Inspect storage conditions and reassess product performance.
