2.Product characteristics

DCOIT-20 is a highly effective anti-mildew and anti-algae agent, which has a very broad spectrum and long-term sterilization.

DCOIT-20 has a low solubility in water, so the effect is long-lasting.

DCOIT-20 is dispersed in aqueous systems and dissolves in oily paints.

DCOIT-20 is easy to use and can be added in any process.

DCOIT-20 is thermally stable and easy to use.

The outdoor weathering test results of DCOIT-20 show that the effect is good.

3.Instructions for use

The recommended dosage of DCOIT-20 is 0.12% to 0.57% of the total weight of the coating formulation. When DCOIT-20 microbicide is used at the recommended bactericidal level, a separate in-tank preservative may not be required. Dry film protection and wet stage preservation testing for DCOIT-20 fungicide in formulations is strongly recommended. The level of use required to obtain the required level of protection with DCOIT-20 microbicides depends on several factors. These conditions include the climatic conditions in which the paint is to be applied, the type of paint, the conditions of the surface to be applied, and the number of layers of paint to be applied.

4.Packing and storage

DCOIT-20 should be stored in an airtight original container, preferably at room temperature. Protection from frost and heat.If the product does freeze, it must be evenly mixed after preheating and can then be used without any loss of efficacy.

Packing: 20/180/960kg plastic drum packing.

Validity: One year under the specified storage and transportation conditions.

5.Precautions for safe use

DCOIT-20 must be operated in strict accordance with the regulations during use; Avoid contact with skin; Wear protective clothing, safety goggles, rubber gloves; Once in contact with skin, wash immediately with plenty of water and soap; Splash into eyes, immediately clean with plenty of water and buffer; Seek medical attention if necessary.
