Product Description


CAS NO.64359-81-5 dcoit Organic Biocides

Industrial Microbicide for Use in Coatings, Building Materials, Adhesives and Tackifiers



DCOIT-20 is a low VOC (Volatile Organic Compound) formulation of the active ingredient is 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one. It provides the same broad spectrum activity with improved ease of formulation and similarly can be used in both exterior and interior applications. The performance is similar to ROCIMA™ 200,ROZONE™ 2000/ROCIMA™ 342/ ACTICIDE ® DT,Lonzaserve™ 920.

Typical Properties

These properties are typical but do not constitute specifications


greenish-yellow, clear liquid

Active Ingredient

20% dichloroctylisothiazolinone.

Specific Gravity (g/ml) at 25°C

Approx. 0.98 g/cm³

Directions for Use

Recommended use levels of DCOIT-20 microbicide range from 0.12% to 0.57%, as supplied, on total weight of paint formulation.

When DCOIT-20 microbicide is used at recommended mildewcidal levels, a separate in-can preservative may not be needed. Testing DCOIT-20 microbicide in customer formulations both for dry film protection and wet stage preservation is highly recommended.

The usage level required to obtain the desired degree of protection with DCOIT-20 microbicide depends on several factors. These include the climatic conditions where the paint will be applied, the type of paint produced, the condition of the surface being painted, and the number of coats of paint applied. For maximum protection we recommend using 1150 ppm active ingredient (0.57% product as supplied).

Formulating Techniques with DCOIT-20 Microbicide

DCOIT-20 microbicide is a flowable dispersion that is easily incorporated into paint formulations. In principle, it can be added to the paint at any point in the paint preparation process.


DCOIT-20 microbicide should be stored in tightly sealed original containers and preferably at room temperature. Protect from frost and heat.

If the product does freeze, it has to be mixed homogeneously after warming up and can then be used without any loss in effectiveness.
