Silicon carbide micron powder 5um for UV curable coatings
UV curable coatings, also known as photosensitive coatings or UV coatings. It is a coating mainly made of oligomers and cured to form a network structure under the action of ultraviolet light. It has the characteristics of environmental protection, energy saving, fast curing speed, and is suitable for automated production.
The main formulas for UV coatings are oligomers, diluents, photoinitiators, and functional fillers.Silicon carbide micron powder 5um is an excellent functional fillers powder. The main functions and functions adding SiC powder are as follows:
1. Increase the wear resistance and scratch resistance of the coating.
The material hardness of silicon carbide micron powder 5 um is higher than that of alumina. Thus, it has higher wear resistance and scratch resistance.
2. Improve the anti-aging performance of UV curable coatings.
Silicon carbide powder 5 micron can also resist the invasion of corrosive substances such as strong acids and alkalis at high temperatures. It is one of the best corrosion-resistant materials. At the same time, it has good antioxidant properties to prevent the oxidation and yellowing of coatings caused by light exposure.
3. Enhance the volume stability of UV curable coatings.
The thermal expansion coefficient of 99% silicon carbide powder is very small, and its high temperature resistance is strong. Therefore, it can prevent coating deformation.
4. Hydrophobicity.
Green silicon carbide ultrafine powder is insoluble in water and precipitates from water washing, with good fluidity.
