- Features & Benefits
Products properly equipped with antimicrobial agpure® W50 are non-toxic to humans and animals. In contrast to other biocides agpure® W50 is non sensitizing and non allergic to humans in skin contact. Due to the slow and controlled release of biocidal silver-ions from agpure® W50 the antimicrobial effect is persistent. Products containing agpure® W50 can be protected against microbial soiling for a lifetime without being toxic to humans or the environment. agpure® W50 exhibits strong activity against all gram-positive and gram-negative bacteria. Its activity is unaffected by antibiotic-resistance of strains, yeast and fungi. So agpure® W50 is a valuable mean fighting multiresistent germs in hospitals, surgeries, agriculture and in food processing. agpure® W50 itself does not induce or propagate bacterial resistance. agpure® W50 silver nanoparticles exhibit a yellow color due to the plasmon effect. Please consider possible influences on product color. For applications that are very sensitive for even slight color changes there are special agpure® product forms available. Ask our experts. agpure® W50 is free of any inorganic fillers. It can be used for very small structures like microfibers or for very thin coatings.
