Coating method: Epoxy topcoat

1. Product Composition:

The two-component topcoat is composed of epoxy resin, pigment, additives, solvent and polyamide curing agent.

II. Product Features:

The coating is hard and has good adhesion, water resistance, oil resistance and chemical corrosion resistance.

III. Product Applications:

Ideal for large-scale indoor chemical equipment, storage tanks, pipelines, and concrete surfaces requiring anti-corrosion coatings.

IV. Technical Specifications:

5. Supporting paints:

The sequence includes: Epoxy Primer, epoxy iron oxide intermediate paint, and epoxy zinc-rich primer.

VI. Construction Steps:

Step 1: Substrate preparation

1. The steel surface should be cleaned of oil, dust, and loose oxide scale, and then shot blasting or sandblasting should be performed to meet the Swedish rust removal standard Sa2.5.

Note: Sa2.5 standard: Thorough abrasive spraying to completely remove rust and oxide scale. After dust removal, the steel surface exhibits a near-white metallic luster with only minor surface imperfections.

2. After substrate preparation, apply epoxy zinc-rich primer or epoxy primer, and optionally apply epoxy iron oxide intermediate coat as needed.

Step 2: Painting process

1. Before painting, first mix the paint slurry thoroughly. Then, according to the required amount for application, combine the paint slurry with the curing agent in the specified ratio and mix evenly. After 20 minutes of curing, proceed with the application.

2. The prepared paint must be used within 8 hours at 25℃.

3. Mixing ratio: Paint: Curing agent: Diluent =100:25:15

4. When applying epoxy primer or epoxy iron oxide paint over existing epoxy coatings, the topcoat should not be applied more than 7-10 days later (at 25°C). For epoxy topcoat, the reapplication interval is 24 hours (at 25°C).

7. Construction Environment:

1. The temperature of the steel plate to be painted should not exceed 50℃. The ambient temperature for painting should be between 10℃ and 35℃. If the temperature drops below 10℃, the curing reaction between epoxy paint and curing agent will slow down, making it unsuitable for painting.

2. The substrate temperature must be at least 3℃ above the dew point, and the ambient humidity should not exceed 80%.

8. Painting method:

9. Precautions:

1. The Star Original Epoxy Paint must be diluted with its exclusive diluent.

2. When the construction temperature drops below 10℃, the curing reaction slows down and drying time increases. Therefore, the temperature should be maintained above 15℃.

3. Construction is not recommended under conditions of rain, fog, snow, direct sunlight, or humidity exceeding 80%.

4. The film is not resistant to outdoor sunlight, and is generally used for indoor corrosion protection.

10. Storage, Transportation, and Shelf Life:

1. The product should be stored in a well-ventilated and dry place, and should be protected from direct sunlight. In summer, appropriate cooling measures should be taken when the temperature is too high.

2. During transportation, protect the product from rain and direct sunlight.

3. The product has a shelf life of 12 months. During storage, the packaging must remain unopened and meet storage conditions. After the expiration date, the product may be inspected according to the specified items in the product standards. If the results meet quality requirements, the product may still be used.

11. Safety and Environmental Protection Notice:

1. This product is flammable. Ensure proper ventilation and take necessary protective measures during application.

2. If the skin is stained with paint, wash it immediately with soap or other cleaning agents and plenty of water.

3. The disposal of waste paint and packaging materials must comply with local environmental regulations.
