1, the bacteria and mold have a strong inhibition ability, with broad-spectrum bactericidal does not produce resistance, the effect is long lasting effect period.
2, wide pH range: pH applicable range between 2 ~ 12.
3, ultra-fine powder, easy to use, easy to add
4, non-flammable, flame retardant.















Polymerized olefin wax. The relative molecular mass of wax of the same species is lower, and its melting point is correspondingly lower. Generally, the melting point should be 100~130℃, which gives the coating film the best slip, scratch resistance and anti-blocking properties. Some scholars believe that when the melting point of polymeric wax is above 150°C, because its particles are hard, it has a damping effect on friction, and the slipping effect will decrease.
Homopolymer wax used as slip and anti-scratch agent in coatings. In terms of its compatibility with the coating base material, polyethylene wax is better than polypropylene wax and polytetrafluoroethylene wax, and it has a wide range of applications. In particular, lower molecular weight polyethylene waxes are widely used in printing inks to improve the surface properties of inks, such as anti-blocking requirements. Because polytetrafluoroethylene wax has a very low surface free energy and can give a very low coefficient of friction to the surface of the coating film, it is more effective than polyolefin wax in terms of slippage and scratch resistance.

Teflon wax is characterized by stability, insoluble in solvents used in general coatings, and good thermal stability (melting at a temperature above 310°C). However, when used as a slip and anti-scratch agent, it has two major disadvantages: it is more expensive and relatively dense, it is easy to produce precipitation in the coating, and it hinders the necessary floating and aggregation on the surface of the coating film, and it is difficult to achieve its full play. The surface energy is extremely low, and the purpose of reducing the friction coefficient is good. Therefore, the process has been improved. The polytetrafluoroethylene wax is coated on the surface of the polyethylene wax particles or bonded with the polyethylene wax. The relative density of the modified wax is between the two. Polyethylene wax achieves the purpose of suspending, preventing precipitation and floating on the surface of the coating film in the coating. It can also play the effect of PTFE wax in slipping, scratch resistance and anti-blocking, which is not as good as general wax, and reduce Price of the product. It is especially recommended for coil coatings. In addition to improving the smoothness, scratch resistance and anti-blocking of the coating film surface, it also improves the hardness of the paint film, improves water resistance, and improves the shrinking bead effect. Extend the continuous effective use time of the coating film. Such products include Ceraflour 996 produced by BYK in Germany.
