The use of glass powder, can increase the transparency of paint

Uses of glass powder that can increase paint transparency
Glass powder is unfamiliar to many people. It is mainly used when painting to increase the transparency of the coating and make the coating fuller when it forms a film. Here is an introduction to the characteristics of glass powder and the use of glass powder, learn more about the materials used for decoration.
Product Characteristics
Glass powder has good refractive index, mixing with paint can improve the transparency of paint, especially furniture paint. Moreover, even if the added amount of glass powder reaches 20%, it will not affect the performance of the coating and is more resistant to scratching. The added glass powder will not increase the viscosity of the coating and will not affect the application. It is also resistant to yellowing, high temperature weathering, UV and natural chalking, and PH stability. Its strength is high, so the abrasion and folding resistance of the coating is also improved.
Glass powder is made from environmentally friendly raw materials. Through low temperature treatment and multi-stage sieving, the particle size of the powder obtains a Z-narrow accumulation peak. This result also makes mixing easy, as it can be dispersed with a general-purpose disperser and then used in coatings to mix well.

Applications of Glass Powder
1. When glass powder is used in matte resin, the proportion of matte powder can be reduced.
2. The dosage is about 3%-5%. In order to ensure the transparency, the dosage of bright paint can be around 5%, while the dosage of color paint can be around 6%-12%.
3. In order to avoid particles in the use of glass powder, you can add 1% of the dispersant, the dispersing speed should not be too fast, otherwise the color will turn yellow and black, affecting the painting effect.
Difficulties in practical application
1. It is difficult to prevent sinking. The density of glass powder is higher than that of paint, and it is easy to precipitate at the bottom of paint after dilution. To prevent this, it is necessary to use a combination of horizontal and vertical anti-settling principle, so that the paint will not settle significantly for a period of time after dilution, and even if it is delaminated, it can be used only by stirring.
2. It is difficult to control. Adding glass powder in paint is mainly for its transparency and scratch resistance, so the lack of feel of the paint film can be solved by adding wax powder in the paint.
Through the introduction we all know the use of glass powder, the correct use or rely on professional construction personnel to deploy. But as a homeowner know this, you can also properly supervise the progress of the project, to avoid the omission of this step in the construction, resulting in poor painting results.
