Application field

It is a widely used chemical that forms an integral part in paints, cosmetics, inks, dyes, water-based polymer, metal cutting fluids, adhesives, and paraffin liquid industries. It is also used in the process of water treatment in the industries of petrochemicals, central air conditioning, electricity and industrial cooling water. It can efficiently strerilize and remove algae.

Performance characteristics

  • Using a small amount of isothiazolinones-biocide, many fungi, yeasts and bacterial can be killed.
  • The suitable pH value for use ranges between 2 to 9; free of divalent salt and cross-link no emulsion.
  • This easy to use chemical is miscible with water and can be added in any production step.
  • This chemical with low toxicity must be used in an appropriate concentration, so as to ensure no harm completely.
  • It causes no residue after discharge, and no pollution to the environment.
  • This non combustible chemical can be conveniently transported and used.
  • It is compatible with surfactants, emulsifiers and protein-contained agents.
  • It has an excellent effect on pseudomonas.
  • It doesn't contain any formaldehyde and VOC.

Usage and Cautions

  • When using it for treating water, dilute it into a 1.5% aqueous solution and then add this solution at a quantity of 80 to 100 ppm for one or two times every week, based on the multiplication of bacteria, algae and other micro organisms.
  • Users must avoid direct eyes’ contact with this solution. If case of contact, rinse eyes with water immediately. Long-term contact of this chemical with skin is harmful.
  • Contact of this chemical with reducible metals, like iron and aluminum is not allowed during storage, as it can result in decomposition.
  • This chemical has poor stability, therefore, it is not recommended for use in the alkaline medium of pH> 9.0. Quality of a product can decline if one combines it with highly nucleophilic chemicals, like S2- and R-NH2.
