1.What are the components and characteristics of polyester coating?
Composition: A resin formed by the condensation polymerization of polyols and polyacids.
Features: This is the most versatile and economical coating. It has good flexibility and adhesion, offering excellent value for money.
Performance: Balanced overall performance, moderate weather resistance. Suitable for indoor and general outdoor environments.
Applications: Home appliances, furniture, architectural interior panels, etc.
2.What are the components and characteristics of silicone-modified polyester coatings?
Composition: A portion of silicone resin is introduced into polyester resin. The silicone content is typically between 20% and 50%.
Features: The addition of silicone resin significantly improves the coating's weather resistance and UV resistance.
Performance: Weather resistance, gloss and color retention are superior to ordinary polyester, resulting in a longer service life. Cost is higher than polyester.
Applications: Building exterior walls, roofs, and other applications requiring high weather resistance. This is one of the most widely used coatings in the construction industry.
3.What are the components and characteristics of high-durability polyester/high-weather-resistant polyester coatings?
Composition: Polyester resin made using superior monomers and advanced synthesis processes.
Features: Its weather resistance reaches or even exceeds that of ordinary silicone-modified polyesters, while maintaining good processability.
Performance: Super weather-resistant, UV-resistant, and colorfast.
Applications: High-end construction projects requiring high color and durability.
4.What are the components and characteristics of polyvinylidene fluoride (PVDF) coating?
Composition: Typically refers to PVDF resin, with a fluorine content as high as 70%. The most classic formula is 70% PVDF resin and 30% acrylic resin.
Features: This is a top-tier topcoat formulation. It possesses exceptional weather resistance, chalking resistance, and stain resistance.
Performance: Maintains stable color and gloss even in harsh environments (such as industrial atmospheres and marine climates), and has an extremely long service life (up to 20 years or more).
Applications: Exterior walls and roofs of landmark buildings, airports, stadiums, and other high-end buildings.
5.What are the components and characteristics of acrylic coatings?
Composition: Primarily composed of acrylic resins.
Characteristics: High hardness, high gloss, and good chemical resistance.
Performance: Good color retention, but generally less flexible than polyester.
Applications: Currently used less frequently, with some applications in specific fields requiring high hardness.
