Polyester mainly refers to a kind of substances, which contain ester groups. Equivalent to metal. Resin has two meanings. One refers to material, which is equivalent to alloy, such as phenolic resin, which is equivalent to copper aluminum alloy. It's just the name of a kind of substance. The second meaning refers to that the initial raw material without adding any substance, that is, the masterbatch, is pure without adding any additives. It is a production concept. Therefore, the resin mentioned in PET chip refers to this concept. After slicing, it is one by one, which can be sold as masterbatch, so it is called PET resin.
The service life of paints depends on different products. The liquid mineral texture products are based on modified silicone resin emulsion, and the special coating technology is used to coat all kinds of colored paint into colloidal water color particles, which are uniformly and steadily suspended in the specific water dispersions. The coloring of various coloring particles is kept unchanged, and the pigments are not precipitated in water. Then the service life of this exterior wall coating is about 15 years.
Liquid marble texture products use unique wrapping technology to make the products fully hydrated, with extremely low VOC content, which greatly improves the service life of exterior wall paint; High fidelity, the surface of the coating is concave convex and soft, and the colors penetrate each other, which can imitate the natural granite in color; Environmental protection and energy conservation, which can replace the precious stone materials with increasingly scarce resources, and cooperate with the external thermal insulation of the external wall for professional imitation granite decoration, which fully meets the national energy-saving and environmental protection requirements of building coatings; Excellent decorative effect, random color depth and pattern size.
