Introduction
Composition
The paint consists of fluororesin, pigments, additives, and solvents as component A, and the curing agent as component B. When in use, the two components are mixed in the specified ratio.
Characteristics
This paint has excellent adhesion, outstanding chemical resistance, a long aging time of up to 15 to 20 years, high hardness, wear resistance, good toughness, temperature resistance, stain resistance, oil resistance, water resistance, and can cure at room temperature.
Applications
Used for coating ships, highway guardrails, outdoor port machinery, transmission towers, microwave transmission towers, offshore drilling platforms, outdoor chemical storage tanks, bridges, oil field drilling equipment, containers, etc.
Construction Reference
1. Requirements for the surface to be coated:
a. No oil stains, no dust, no rust. b. The surface is clean and not damp.
2. Apply primer: spraying or brushing is acceptable.
Use a special primer and thinner for nitrogen paint.
Film thickness: dry film thickness: 30 microns.
Drying time: 25℃, 24 hours.
3. Requirements for the surface of the primer:
a. The base layer is uniform, not leaking, not rough, and has good adhesion.
b. The base layer is free of defects, flat, without dust, oil stains, and not damp.
4. Adjusting the topcoat:
Mixing ratio: A component: B component 21:0.045 (weight ratio). Use a special thinner D-X-2 for fluorine paint to adjust the viscosity of the paint.
Curing time: Under conditions of 15-40℃, cure for 30-50 minutes before spraying.
Usable period: 25℃, 8 hours; 35℃, 6 hours; can be adjusted according to temperature.
5. Spraying the topcoat: spraying or brushing is acceptable.
Generally, two coats of topcoat are sufficient. Dry film thickness is 20±5 microns per coat. Interval time is 1-2 hours.
The time limit between the topcoat and primer is 24 hours (should be tested first to ensure no biting through before spraying).
6. Drying time: At 25℃, surface dry: 20 minutes; fully dry: 24 hours; completely cured: 7 days.
7. The number of spraying coats and thickness of primer and topcoat should be based on the usage conditions and design requirements of the coated object.
Storage: Store in a cool, dry place away from fire sources. Effective storage is one year.
Packaging: Metal paint: 18kg/set; solid color paint: 24kg/set.
