Dispersed silicon dioxide is common additive industrial coatings. Adding silicon dioxide can enhance the paints abilities and quality.
Silicon dioxide is a natural mineral and it is exist in different types of rocks and earth. So it can also be called silicon sand and silicon
quartz.
In industrial coatings, adding silicon dioxide can decrease the thick strength which can make it easier to apply.Silicon dioxide with high
dispersion ability can improve the paints' durability. It can enhance the hardeness and scratch resistance of surface. This is a crucial key
in industrial coatings. Because indutrial coatings are normally used in outdoor.
Besides, silicon dioxide can improve coatings adhesion level to its using goods' surface. It is important to reduce the possibility of cracking
by using a short time.
In addition,silicon dioxide can help to improve the coatings' quality and abilities. Through this, we can help to produce a better finished product
that is more durable and long-lasting.
The more commonly used matting agents are divided into two categories: organic and inorganic: Inorganic matting agents are mainly silica matting
agents, whose chemical composition is ultrafine sio2, and can be divided into two types of surfaces: organic-treated and untreated. Now we mainly
discuss the application of silica matting agents in coatings. Pigments or fillers are added to the coating and evenly distributed in the coating film to
produce a micro-rough surface. Light calcium carbonate or talcum powder is used to produce matte coatings. The dosage is large and often exceeds
the critical pigment volume concentration of the coating, making the coating have poor physical properties, such as stratification and hard precipitation.
The use of matting powder can avoid the larger the surface particles, the greater the micro-roughness and the lower the gloss.
