Silver technology biocides

Silver technology biocides are chemical or microbiological substances, that are intended to neutralize harmful organisms in the non-agricultural sector. Among others, these harmful organisms may include fungi, bacteria, yeasts and algae. Biocides provide protection for health and protection of products. Therefore, biocides play a significant role in the maintenance of health and hygiene standards.


Our biocides (biocides based on silver technology) are used in the production of rubber, paints, printing inks, industrial paints, adhesives, sealants and metal processing. They are used for water treatment and for preservation of water-based chemical-technical products.
