1,  Add a small amount that is effective for mold, bacteria, yeast and algae, when used in industrial mold, the use of concentration in 0.05-0.2% can maintain a good sterilization effect.
2,  It is safe for human and animal in the range of use.
3,  Adding to resin does not affect the chemical properties of the resin itself.
4,  Good chemical stability, not hydrolysis, stable in weak acids and bases.
5, It can stop the development of microorganisms for a long time, and the effect is long-lasting and resistant to rain.
6, Weather resistance, good heat resistance, no decomposition at temperatures below 300℃.
7, No corrosion of metal.
8, Wide bactericidal spectrum, low concentration of bacterial inhibition. It has strong killing effect on mold, fungus and some bacteria that cause common harm in industry.

 

 

 

 

 

 

 

 

 

 

 

When the amount of surfactant is in a lower range, the surface tension decreases rapidly as the amount of use increases; when the amount increases to a certain amount, the surface tension basically maintains a constant value, that is, the excess surfactant will reduce the surface tension of the system and reduce the surface tension of the system. no help.
The film-forming mechanism of water-dispersible coatings is different from that of solvent-based coatings. When latex paint forms a film, it does not only rely on solvent volatilization or cross-linking to solidify to form a film, because latex paint is a heterogeneous dispersion system, and its continuous phase is water and others. The water-soluble component and the film-forming polymer are dispersed in the continuous phase in the form of tiny latex particles. When the water gradually volatilizes or is absorbed by the porous surface, these latex particles gradually approach and contact, and are dispersed under the action of the capillary pressure of the water. The latex particles are pulled together and squeezed to deform, tightly coalesce with each other to form a continuous coating film. Due to the low volatilization rate of water, the film-forming process oxidized polypropylene wax  is a relatively slow process. Figure 8-8 shows the film forming process of latex paint.

In the process of latex paint from construction to film formation, because its viscosity changes little with solvent volatilization, the anti-sagging property of latex paint after construction is a very important issue. Usually thickeners are added to latex paints to increase the viscosity of the system, improve storage stability and sag resistance, but thickeners with poor rheological properties will reduce the leveling of the coating during coating, and brushing often occurs. Marks, roll marks, orange peel and other defects, so the imbalance between leveling and sagging is a common problem of latex paint.
