2. VK-L08 offers both acid and alkali resistance and abrasion resistance. It has a high hardness of 6-7H, making it wear-resistant and scratch-resistant. Additionally, it boasts multiple advantages such as abrasion resistance, strong adhesion, and convenient application.

3. The extensive application of nanomaterials, VK-L08 exhibits extremely high barrier properties and very low permeability, preventing the penetration of acids, oxygen, and water vapor.

4. The integration of multiple nanomaterials endows VK-L08 with chemical inertness, thereby providing **exceptional stability** against acids and alkalis. It also exhibits extremely high tolerance even at certain temperatures.

5. High brightness

12. Other environments that simultaneously require acid resistance, alkali resistance, heat resistance, and wear resistance.

Construction and Usage Methods:

To ensure the quality of the coating, please carefully read the usage instructions and the coating specifications corresponding to the product.

1. Substrate Treatment:

Before painting, remove oil, residual rust, oxide scale, etc. from the substrate surface. All steel surfaces to be coated must meet the Sa2.5 level requirement. When performing local coating repairs, the steel surface must be ground to the St3 level. The surface roughness should be controlled within the range of 25 to 40 μm.

2. Mix

Mixing Ratio: A (Base Paint) : B (Hardener) = 5:1 (by weight). When mixing, slowly pour Hardener B into Base Paint A while continuously stirring, and stir for approximately 2–5 minutes until evenly mixed. Then it is ready for application. C (Thinner) can be used to adjust viscosity freely; stir evenly and choose the amount of thinner based on your actual needs. Mechanical stirring is recommended.

The sealed shelf life of the mixed coating is 1 to 2 hours. Please plan the usage according to the construction progress.

3. Environmental Conditions

Spray coating should be carried out as soon as possible after substrate treatment, generally not exceeding 4 hours.

4. Coating/Painting

This coating can be applied using brushing, airless spraying, and air-assisted spraying methods. **The first coat should be applied thinly to serve as a transition layer, aiming to improve adhesion between the coating and the substrate. The second coat should be applied approximately 2-3 hours after the first coat becomes surface-dry, with the time slightly extended or shortened depending on the actual temperature and humidity.

The drying method can be chosen according to the construction conditions.

At 25°C, air-dry naturally with a light breeze for 4-8 hours, and fully dry in 24 hours.

B: Dry at 60°C for 0.5-1 hour. For high hardness and strong corrosion resistance, B drying is recommended.

5. After use, A, B, and C should have their unused portions immediately sealed tightly to prevent the substances inside from volatilizing or condensing, which could cause them to thicken and shorten their shelf life.
