Improve the physical and mechanical properties of the paint film

It is well known that composites using sheet and fibrous fillers have many excellent properties such as dispersion stress, improved impact and tensile strength, improved dimensional stability and deformation resistance, and changes in many physical moduli, etc. The mechanism is like steel bars in concrete, and the principles are well known.

Improve the abrasion resistance of the paint film

The hardness of the resin itself is limited, and many fillers are not strong (such as talc). In contrast, mica is one of the components of granite, and its hardness and mechanical strength are large. Therefore, the addition of mica flakes as a filler in the coating can significantly improve the antiwear performance. This is the reason why car paints, road coatings, mechanical anti-corrosion coatings, wall coatings, etc. prefer to use mica powder.

Insulation performance

Mica has a very high electrical resistance and is itself the most excellent insulating material. Using mica pigment to improve the insulation properties of paint film is a well-known technology, so it is not to say much. It is very interesting that it is a compound of silicone resin or silicone boron resin, which is converted into a ceramic material with good mechanical strength and insulation properties when subjected to high temperature. Therefore, wires and cables made of such insulating materials remain in an insulated state even after being burned in a fire. This is very important for mines, tunnels, special buildings, special facilities, etc.

Flame retardant

Mica powder is a valuable flame retardant filler. If it is combined with an organic halogen flame retardant, it can produce flame retardant and fire retardant coatings.

Mica powder also has many properties, such as UV resistance, infrared performance, reduced sedimentation, heat radiation and high temperature coatings. For those who want to know more about it, we will see you next week!
