1, such as latex paint, diatomaceous earth paint, putty paint and other processing, add 0.3 ~ 0.5% (O.W.F), can be made into anti-mold anti-bacterial products.

2, water-based polyurethane, water-based paint, water-based ink, water-based adhesives, styrene, rubber, silicone compounds, add 0.3 ~ 1% (O.W.F), can be made into anti-mold anti-bacterial products.

3, the anti-mildew agent KP-M20 and raw materials mixed according to the above amount, mix well, other processes remain unchanged.














The macromolecularization studies of α-hydroxyacetophenone series photoinitiators (including benzoin, HCP K, HM PP, etc.) have shown that if the hydroxyl group is esterified, the photoinitiation activity will be greatly reduced. The photoinitiator is connected to the macromolecular chain, and the photolysis activity is basically not affected. In addition, the overall photoinitiation activity is also related to the macromolecular chain structure, the length and flexibility of the link arm, and the distribution density of the active center on the molecular chain. There is a close relationship.

Macromolecular HM PP mainly comes in two forms, HM PP-1 and HM PP-2. The relative molecular mass of HM PP-l is about 2000. It was launched by Lamberti Company in Italy. The trade name is KIP 150. It can It is said that it is a more successful commercialized macromolecular photoinitiator. Because of its good miscibility and low volatility, it is recommended for use in emulsion light-curing water-based systems with good dispersion stability.
KIP photoinitiators can meet most commercial requirements, and the price is relatively low among all kinds of macromolecular photoinitiators, and has been applied in some occasions. Although it overcomes the problems of migration, volatilization, odor, etc., because its main chain is a poly(amethylstyrene) structure, high density polyethylene wax it is relatively rigid, which may increase the hardness and brittleness of the cured film.

Another macromolecular HM PP photoinitiator is obtained by homopolymerization of 2-hydroxyl 1-[4-(2-hydroxyethoxy) phenyl] -2-methyl-1-acetone acrylated ( HM PP-2). This monomer was once produced by Ciba Company. As a photoinitiator, the relative molecular weight of HM PP-2 is 3000~10000. The photoinitiation activity is lower than that of small molecule HMM P, but it is comparable to the corresponding monomer acrylated HM PP. Compared with, the photoinitiation activity is slightly higher.
