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).
