In the rainy and humid environment of East China,Outdoor advertising fabricThere are several options for the anti mold coating process, each with its unique advantages:

1. Polyurethane coating process

Polyurethane coating is formed by the reaction of polyols and isocyanates, forming a three-dimensional network structure that can effectively prevent moisture penetration and prevent advertising fabrics from becoming moldy due to moisture. In addition, polyurethane coatings also have UV resistance and chemical corrosion resistance, which can resist various pollutants in outdoor environments.

2. Coating process of moisture-proof and mildew proof coatings

This coating process requires the use of synthetic resin exterior wall coatings with good moisture and mold resistance properties. During construction, first clean the base layer, then apply the base material, and then apply latex paint in sequence. This coating process can enhance waterproof performance, prevent slight cracking of the wall, and further improve the anti mold effect.

3. Inorganic coating process

Inorganic coatings have stronger stability in humid environments and good moisture and mold resistance. During construction, it is necessary to first inspect and clean the wall surface, repair leaks and address problematic areas, then apply and cure the primer, and finally proceed with the main coating. Inorganic coating can effectively prevent moisture infiltration and reduce the conditions for mold growth.

4. TPU film composite coating process

The TPU film composite cotton fabric adopts a "sandwich" structure design, with an outer layer of TPU protective film, which has excellent UV resistance, stain resistance, and wear resistance; The inner layer is a functional coating, and special functional coatings such as anti mold agents can be added according to specific applications. This coating process not only enhances the waterproof performance, but also further improves the anti mold effect by adding anti mold agents.

5. PVC coating process

PVC coated cloth has excellent waterproof performance, which can effectively prevent rainwater infiltration, and also has moisture-proof performance, which can reduce water absorption and diffusion, maintain dryness and cleanliness, and further reduce the chance of mold growth. In addition, PVC coated cloth can also be added with anti mold agents to further enhance the anti mold effect.

6. Nano anti mold coating process

A new type of anti mold coating technology uses nanomaterials such as nano titanium dioxide or chitosan nano silver as antibacterial layers. These materials can effectively inhibit the growth of mold and endow the surface of the coating cloth with waterproofness, avoiding moisture and mold.

Summary

In the rainy and humid environment of East China, if extremely high anti mold performance is required, it is recommended to choose TPU film composite coating process or nano anti mold coating process, because they not only have excellent waterproof and moisture-proof performance, but also can further improve the anti mold effect by adding anti mold agents or using nano antibacterial materials. If considering cost and construction convenience, PVC coating process and polyurethane coating process are also good choices.
