Application and Activity

CMIT/MIT-1.5  is a wet state preservative with a very wide application field such as paints,plasters, adhesives, inks, dispersion and emulsion binders and aqueous technical products in general. It can be used alone or in combination with other active ingredients such as methylisothiazolone (MIT-10) or formaldehyde donors.

CMIT/MIT-1.5  is a proven slimicide in paper manufacturing. CMIT/MIT-1.5 contains neither formaldehyde nor cationic or phenolic substances. Therefore, it is particularly suited for use in products not compatible with these substances.


The number of technical products being preserved with CMIT/MIT-1.5 is increasing steadily and it is not always possible to predict its suitability. The optimum use should be established by a preliminary experiment. In critical cases, predilution with water is often helpful. The optimum dosage rate of CMIT/MIT-1.5 depends upon the degree of contamination and the susceptibility of the product to be preserved.

Occasionally, the degree of contamination exhibits seasonal fluctuation, so that a periodical determination of germ counts can assist in choosing the optimum dosage rate.Therefore, the ranges of concentrations listed below should be taken as general guidelines only:

Binders                         0.05 - 0.3%

Other products              0.05 - 0.15%
