Abstract: DCOIT-99(4,5-Dichloro-2-octyl-isothiazolone, CAS: 64359-81-5) is a new type of industrial anti-mildew agent, which can simultaneously prevent mildew, antibacterial and anti-algae, and is one of the effective antibacterial agents in the industrial field. DCOIT-99 can be added to: rubber and plastic products, water-based coatings, Marine paint, ink, paper, etc., than other inorganic or organic fungicides can only antibacterial or only anti-mold effect is more excellent. DCOIT-99 can replace organic, TBTO, TCMTB and other compounds, low toxicity, no VOC.

2.Product characteristics

2.1 DCOIT-99 is stable in Marine paint.

2.2 DCOIT-99 can effectively kill bacteria, fungi, seaweed and other Marine organisms in a broad spectrum.

2.3 DCOIT-99 provides durable protection that matches or exceeds the effectiveness of TBTO.

2.4 DCOIT-99 does not contain heavy metals. When released into the environment, DCOIT-99 quickly seeps into sediments and breaks down, so it does not accumulate in Marine organisms.

2.5 DCOIT-99 is stable under strong UV and acid rain conditions.

3.Application field

DCOIT-99 as a dry film anti-mildew agent and anti-algae agent is mainly used in Marine paint, paint, gypsum board, plastic, bamboo, wood and other fields. DCOIT-99 can also be used in adhesives, inks and other systems. DCOIT-99 is soluble with oil-based products and can be added in the first stage before dispersion. DCOIT-99 showed good stability in ionic surfactants and emulsions. In order to achieve long-term use effects, it is recommended to add 5%-20%DCOIT-99 to Marine paint. DCOIT-99 is soluble with oil-based products and can be added in the first stage before dispersion.

4.Precautions for use

When using DCOIT-99, wear protective clothing, rubber gloves, eye masks and masks to avoid contact with skin, eyes and mucous membranes. In case of contact with DCOIT-99, wash immediately with plenty of water, do not delay, please seek medical attention in time.
