GENERAL DESCRIPTION
AXCIDE LA 1209 is a combination biocide of Isothiazolinones and Bronopol. It has a broad-spectrum activity in inhibiting bacteria, moulds and yeasts in aqueous products. It is specially formulated for wet preservation of Magnesium and Copper ion-sensitive water based system. It is formulated with sodium salt stabilizer and never contains with volatile organic chemicals (VOC).
Composition
5-chloro-2-methyl-4-isothiazolin-3-one (CIT), 2-methyl-4-isothiazolin-3-one (MIT) and mixture of Bronopol.

APPLICATIONS
AXCIDE LA 1209 is an excellent liquid biocide; it can inhibit the growth of microorganisms effectively in water based emulsion painting, polymer emulsion, adhesives or glue, filler and sealant, metal working fluids and wet state areas. The growth of microoganisms can be controlled significantly with a low concentration of chemicals. The ideal chemical dosages is 0.05-0.40% of total amount to be preserved, it also depends on susceptibility to microorganisms and storage condition.
The following table is shown some typical microorganisms and corresponding to MIC value (calculated as active CIT/MIT ppm).
