2K paint requires specific environmental conditions during the drying and curing process. If the temperature is too low or too high, and the humidity is too high or too low, it will affect the curing effect of the paint and may cause the paint film to crack.

After high temperature construction, hot melt marking paint cools quickly and cures quickly. During the cooling process, heat is dissipated to the outside, making the surface temperature of the marking paint high for a short time, generating a sense of heat.

The mixing ratio of 2K acrylic paint varies from manufacturer to manufacturer and specific product, but the common ratios are usually 4:1, 3:1 or 2:1, that is, the ratio of base to curing agent is 4:1, 3:1 or 2:1.

Zinc-rich primers are particularly suitable for steel protection in highly corrosive environments. For example, steel structure bridges, marine engineering facilities, petrochemical equipment, etc., these facilities are exposed to corrosive environments such as moisture, salt spray and chemicals for a long time.

For most Polyurethane Enamel Paint, under standard room temperature conditions (about 20℃, 50% humidity), the surface drying time is usually between 30 minutes and 1 hour. The surface drying time of water-based Polyurethane Enamel Paint may be slightly longer, usually around 1 to 2 hours.

Two-component high build primer is a more common type, and its main components are primer and hardener. The usual mixing ratio is 4:1 or 5:1, that is, four or five parts of primer correspond to one part of hardener. This ratio helps the primer cure quickly and ensures a strong and smooth coating.

Metallic paints that do not require primers are: 1. Direct-to-Metal Paint (DTM) 2. Alkyd Paint 3. Epoxy Zinc-Rich Paint 4. Polyurethane Paint

quick-drying spray paints are the fastest drying paints, usually drying within a few minutes, making them ideal for small-scale repairs and decoration. Acrylic paints and latex paints are also fast-drying paints, suitable for large-area wall painting and home decoration.

Compared with the complex construction of industrial paint, commercial paint is more suitable for non-professionals to operate by themselves, especially in home decoration, where users can usually complete the painting work easily.

Polyurethane enamel paint is a high-performance coating with polyurethane resin as the main component, which has strong weather resistance and abrasion resistance. It is usually applied to surfaces that require high gloss and durability, such as exterior coatings of automobiles and ships.
