HeiQ AGS-20 - antimicrobial silver powder

The HeiQ AGS-20 powder is a microcomposite structure composed of silver particles supported throughout a matrix of amorphous silicon dioxide . The agglomerated SiO₂ matrix forms a particle with a typical size of a few micrometers. Each silica particle contains many embedded silver metal particles . These silver particles are found embedded throughout the silica structure. The silver particles act as a reservoir for release of silver ions (Ag+) upon contact with water. These silver ions are active agents against microbes. The presence of both surface and embedded silver particles gives the material a combination of immediate antimicrobial activity combined with long-term durability. The fine size of the microcomposite particles allow them to be readily mixed into a variety of substrates including e.g. textile finish, synthetic fibers, coatings and plastics.
