Yuanlei Small Classroom | Composition and Advantages of Transparent Powder Filler



Transparent powder is a mixture of several non-metallic minerals, with high transparency, good whiteness, non-toxic, tasteless, acid and corrosion resistance. With high transparency, the refractive index of the filling material itself is very close to that of most synthetic resins, so the filling amount of the filler does not affect the transparency of the finished product; it can improve the surface smoothness and abrasion resistance of the product; low oil absorption, large filling amount, which is beneficial to reduce the manufacturing cost of the product.


Transparent powder is a common name in the coating industry. Although more than 50% of coating manufacturers use transparent powder more or less, there is no unified standard or method for what kind of powder transparent powder is. In fact, transparent powder is not a single powder, it is in addition to the main ingredients of natural mineral rock, but also add special synthetic accessories mixed grinding modified modulation. The main component is a composite silicate containing magnesium, aluminum and calcium, which is an inorganic salt, and contains some sulfates and impurities.



Transparent powder is a new type of functional transparent filling material, which has the characteristics of high transparency, good hardness, good hue, high gloss, good collapse resistance and less dust during use. Widely used in oily furniture paint, decoration paint, adhesives, inks, and plastics. At first, transparent powder was only used in oily wood paint. In a few years, the market reaction gradually changed from unfamiliar and understanding to cautious use and a large number of application stages. From a single paint industry to the paint industry, to the entire chemical industry.


Transparent powder is an inorganic filler. Its remarkable characteristics are: high transparency, high hardness, and high toughness, which greatly improves the quality of the paint film of the paint. Its use value is recognized by the paint industry, and some well-known companies have adopted it in large numbers. Transparent powder has good chemical stability, acid and alkali resistance, and does not contain toxic and harmful substances, allowing customers to use it at ease.


Transparent powder in the application, there are several small problems need to pay attention:


The 1. is that its high hardness and high toughness will cause the paint film to be difficult to polish, which needs to be changed from the concept, because the hardness and toughness increase, which means that the quality of the paint film is improved, and the relative polishing difficulty is also increased.

2. transparent powder is difficult to prevent settling. There are many successful experiences in the coating industry in the prevention of settling of pigments and fillers. Usually, there are two principles for preventing settling: one is longitudinal anti-settling and the other is horizontal anti-settling. As soon as the transverse and longitudinal cross, it will form a reticular structure with the best anti-settling effect. Of course, anti-settling is not absolute. When the paint is thin, there is still a tendency for transparent powder to sink compared with resin, because its specific gravity is larger than that of resin, so the spraying time is required to be adjusted appropriately.

3. some transparent powder on the market is very easy to absorb moisture, so the packaging must be moisture-proof.

Transparent powder as a kind of outstanding performance, more economical, environmental protection, the use of more secure functional transparent filling material, will bring a new pattern for the polymer material filling material industry.

Wet mica powder is widely used, not only in coatings but also in rubber. Below, the editor will take you to understand the application of wet mica in rubber.

Yuan Lei's Little Knowledge | Performance Requirements and Types of Fillers for Coatings


Fillers in coatings are usually white or slightly colored pigments with a refractive index less than 1.7. It has the basic physical and chemical properties of pigments used in coatings, but due to its refractive index being similar to the film-forming material, it is transparent in coatings and does not have the coloring and covering power of coloring pigments. It is an indispensable pigment in coatings.

Yuan Lei's Little Knowledge | Application Effects of Different Mineral Powder Materials in Coatings


In architectural coatings, commonly used mineral materials include barium sulfate, calcium carbonate, kaolin, mica powder, talc powder, quartz powder, silica micro powder, transparent powder, glass powder, wollastonite powder, etc. Reasonable application of various mineral materials can effectively improve or enhance the performance of coatings. Let's take a look at the application of different mineral materials in coatings.
