3000 Mesh low melting point glass powder, glass powder for Marine coatings
Glass powder is a kind of inorganic amorphous hard ultrafine powder, the appearance of white powder. The use of raw materials in the production of high temperature and high purity silicon oxide and alumina raw materials, and then through the ultra-clean production process, the formation of disordered structure of glass transparent powder, stable chemical properties, with acid and alkali resistance, chemical inertness, low expansion coefficient of super weather powder materials;
Glass powder is a kind of transparent powder with high scratch resistance, small particle size, good dispersion, high transparency and good anti-settling effect; After surface improvement, has good affinity, and has a strong steric resistance, can be easily dispersed in the paint, film can increase the fullness of the paint, made of crystal transparency primer, not only maintain a clear transparency, but also provide good scratch resistance.

Description
Introduction
Glass powder is inorganic amorphous hard particle powder, usually used as high transparent and high hardness filling materials. In the production, the raw materials used are PbO, SiO2, TiO2 and other electronic grade raw materials, which are mixed and then undergo solid phase reaction at high temperature to form glass homogeneous with disordered structure. The chemical properties are stable, and its acid resistance has far exceeded that of lead oxide. However, in the expression of chemical composition, it is usually converted into oxides, such as PbO, SiO2, etc. Please note the difference.

Characteristic
| 1. Glass powder has good transparency, high hardness and uniform particle size distribution. | |||
| 2. Glass powder has good dispersibility and compatibility with resin and other components in paint system. | |||
| 3. Glass powder after surface treatment for many times, in the paint system for filling, paint film without blue light, good recoating. | |||
| 4. Used in high-grade scratch resistance finish paint, can increase the hardness and toughness of finish paint, improve the scratch resistance of paint film, with extinction effect, can improve the weatherability of paint film. | |||
| 5. Compared with talc powder, glass powder is easier to precipitate after paint thinning, so anti-sedimentation measures should be properly strengthened. |
Application description
| Glass powder is mainly used in the production of high-grade furniture as a crystal primer. It is also widely used as a dual purpose paint for the bottom of decoration. Scope of application: polyester paint, polyurethane paint, nitrocellurope paint, alkyd paint, acrylic paint, vinyl paint, PE transparent primer, etc. | |||
| 1.Furniture paint finish, its transparency, thixotropy, hardness, wear resistance are very good, it is recommended to add 3-7%, color paint is 5-10%. | |||
| 2.Suitable for plastic paint, metal paint, the recommended dosage is 10-15%. | |||
| 3, glass powder in the paint is mainly used in the production of high-end furniture as crystal primer, but also widely used as decoration with the bottom of the dual-use paint. It is recommended to add 5%-10%. |
