Any plastic item that comes into contact with moisture—a drain cover, a toilet seal, a rug, a tarp, a pool toy—is a candidate for mold. Microbial colonization not only stains and generates unpleasant odors, but over time it degrades the item. antifungal additive incorporated into the formulation, it protects the product throughout its useful life, from the inside out, and not as a surface treatment that is lost with use.
He zinc pyrithione It is a broad-spectrum, highly efficient biocide. It inhibits the growth of gram-positive and gram-negative bacteria, as well as fungi, mold, and algae. When incorporated into the compound, it migrates slowly to the surface and maintains sustained antimicrobial action, preventing the generation of unpleasant odors and the degradation associated with constant exposure to moisture.
In the plastics industry, it is used to protect PVC, vinyl acetate, polyamides, polyurethanes, polyesters, and polyolefins. It is also used in the treatment of textiles and in the preservation of paints, coatings, adhesives, and sealants.
The level of protection depends on the part and the environment in which it will be used, so the dosage should be adjusted accordingly. Two additional points should be considered: zinc pyrithione can react in the presence of certain metals, so controlling the other components of the formulation is crucial to prevent discoloration; and prolonged exposure to UV light affects this type of biocide, so for outdoor use, it should be used with appropriate protection. It is recommended to store the product in a dry place and keep it tightly sealed once the packaging is opened.
