JLB50 is a new type of industrial anti-mildew agent, which can prevent mildew, anti-bacteria and anti-algae at the same time, and is one of the most effective anti-bacterial agents in the industrial field. It can be added to wall coatings, emulsions, paints, inks, paper, shoe polish, tents and so on.

It is more effective than other inorganic or organic system which can only antibacterial or anti-mold.













Water-based coatings are usually added with a part of hydrophilic organic solvents, such as ethylene glycol, propylene glycol, ethylene glycol butyl ether, Tax an ol, etc., due to the needs of solubility, film formation or anti-freezing properties. The mixture of organic solvents can greatly reduce the surface tension, and to a certain extent alleviate the poor wetting defect caused by the high surface tension of the water-based paint. Secondly, the composition of water-based coatings is more complex, especially in water-dispersible coatings. In addition to film-forming substances and water, human emulsifiers, dispersants, wetting agents, defoamers, thickeners, and neutralizers are generally added. Agents, film-forming agents, co-solvents, pigments and fillers, etc., make the system prone to problems such as imbalance of surface tension, poor flow and leveling, and poor compatibility.

Some of the substances in water-based coatings are surfactants, which can help reduce the surface tension of the system. For example, wetting agents can be used to help the wetting and dispersing of pigments and fillers, as well as improve the wettability of the coating to the substrate. Although surfactants are effective in reducing the surface tension of water-based coatings, they can also bring some side effects polypropylene wax usage to the coating film, such as reducing the water resistance and weather resistance of the coating film, and too much surfactant will stabilize the foam. In addition, excessive use of surfactants will also cause the surface tension of the coating film to be too low, and repainting on it will cause the recoatability to change and the interlayer adhesion strength to decrease. Therefore, it is necessary to carefully choose the variety and dosage of surfactants. Figure 8-7 shows the relationship between the surface tension and dosage of several surfactant aqueous solutions.
