In-Can Preservation for Paints, Adhesives and Related Products

Chemical Name: 2-methyl-4-isothiazolin-3-one


MIT-50 is an active ingredient solution for the preservation of paints, binder dispersions, adhesives and other technical products.

MIT-50 contains an active substance permitted for use in food contact coatings and adhesives provided that the customary dosage rates are not exceeded.

MIT-50 is a straight aqueous solution of the active ingredient Methylisothiazolone, and does not contribute to VOC and AOX.

Typical Properties

These properties are typical but do not constitute specifications


Colorless to yellowish liquid

Active Ingredient

50% Methylisothiazolone (MIT)





Color (Gardner):

Max. 3

pH (as is)


Specific Gravity (g/ml)

1.10 min at 25°C

Solubility in water

Completely soluble in water


Infinite solubility in water, miscible in a wide range of water soluble solvents.


MIT-50 shows a very good compatibility even after undiluted addition. A series of experiments have shown that viscosity and color of the finished products preserved with MIT-50 remain unchanged.


Temperature: up to 60°C (short periods to 80°C), pH range: 4 to 11

Application and Dosage

MIT-50 combines environmental acceptability with effective preservation. It can be used in a wide range of products such as paints, adhesives, latex emulsions, tackifiers, mineral slurries, pigment dispersions and other technical, water-based products.


The optimum dosage rate of MIT-50 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.

The typical use concentration ranges between 0.01 – 0.03%.
