ACTOMAX® DC63 is a liquid mildewcide for the protection of paint films and coatings. It is an efficient preservative against the growth of surface molds, algae and bacteria.
ACTOMAX® DC63 has a very low water solubility, a high resistance to leaching even on weathered surfaces and provides a long-term protection. Miscible at any proportion with organic solvents such as alcohols, aromatics. Miscible with water with the formation of a milky emulsion.
ACTOMAX® DC63 is a protective agent for coatings. To avoid microbial contamination of the water-based products in the container during storage we would advise to use an in-can preservative as well.

Stable under normal conditions of storage down
to 0°C. If frozen, allow to thaw and stir well
before use.

Product Benefits

  1. DCOIT is a broad spectrum antifouling agent for preventing the growth and settlement of soft fouling (bacteria, fungi, algae) and hard fouling (barnacles) organisms on submerged surfaces. DCOIT exhibits rapid inhibition of growth at very low levels and cidal effects at higher levels or for longer contact periods. DCOIT was shown to be a highly effective antimicrobial agent when tested in standard biocide efficacy tests. Minimum Inhibitory Concentration (MIC) studies were conducted to demonstrate the lowest level of biocide which inhibits the growth of soft fouling (or slimeforming) microorganisms (bacteria, algae, fungi).

  2. The mode of action of DCOIT has been studied and it has been shown that DCOIT reacts with the proteins of organisms that come in contact with the coating surface (for example, algae, seaweed, barnacles). This results in interruption of the metabolic processes that utilize these proteins. Fouling organisms initiate specific physiological activities involved in attaching to solid surfaces that are disrupted by DCOIT. As a result the organisms do not successfully colonize the treated surfaces and biofouling is minimized.
