Applications

Major applications in protective coatings are:

- Control mould growth on aqueous or solvent based exterior paints.

- Control mould growth on aqueous or solvent based stains.

- Prevent fungal growth on masonry paints.

- Prevent fouling of marine coatings by algae, barnacles, tubeworms, mussels, hydroids, tunicates and bryozoans.

NOPCOCIDE N-96-S has several desirable properties for use in these applications:

- Low order of toxicity.

- Hydrolytic stability.

DOW CHEMICAL U.S.A.: DBNPA 2,2-Dibromo-3-Nitrilopropionamide:

Broad Spectrum, Low Persistency Biocide

The DBNPA family of antimicrobials is formulated with a unique, brominated chemical developed by The Dow Chemical Company to provide: (1) broad spectrum control of bacteria, yeast, fungi, slime, and algae at low treatment levels; and (2) rapid decomposition in aquatic environments.

Two biocides are currently available: DOW Antimicrobial 7287 and DOW Antimicrobial 8536. They are 20% and 5% active formulations (respectively) of 2,2-dibromo-3-nitri1opropionamide (DBNPA). These industrial antimicrobials are registered by the Environmental Protection Agency (EPA) for specific end-uses.

Both DOW Antimicrobial 7287 and DOW Antimicrobial 8536 meet the requirements of the Food and Drug Administration (FDA) for use as a slimicide in the manufacture of paper and paperboard intended to contact food.

The 7287 and 8536 products also are authorized for use under the United States Department of Agriculture meat, poultry, rabbit, and egg products inspection programs.

DOW Antimicrobial 7287 and DOW Antimicrobial 8536

For control of bacteria, fungi, and yeasts in paper mills, metalworking fluids containing water, and in enhanced oil recovery systems; for control of bacteria, fungi and algae in industrial recirculating water cooling towers and once-through fresh and sea water industrial cooling water systems; for control of slime forming bacteria and fungi in air washer systems.

The active ingredient (DBNPA) in both formulations has been tested extensively in field installations and is generally compatible with paper mill and cooling water systems, commonly used metal-working fluids, and enhanced oil recovery systems.

Highly reliable, cost-effective antimicrobial protection for water-based formulations

DOWICIL 75 Preservative offers an excellent combination of properties for preserving aqueous solutions

DOWICIL 75 Preservative is the designation for l-(3-chloro-allyl)-3,5 , 7-triaza-l-azoniaadamantane chloride combined with a stabilizer (sodium bicarbonate). It is designed to provide highly effective anti-microbial activity in aqueous formulations, including adhesives, paints, construction materials, latexes, and detergents, to name just a few.

- Effective at low concentrations

DOWICIL 75 provides highly effective antimicrobial activity at low concentrations—typically 0.01 to 0.27% by weight in formulations.

- Broad-spectrum activity

A formulation preserved with DOWICIL 75 is protected against a wide variety of bacteria and fungi.

- Excellent formulation compatibility

DOWICIL 75 has been shown to be compatible with many formulation systems.

- Cost-effective

Because it provides highly effective antimicrobial activity at low concentrations, DOWICIL 75 is one of the most cost-effective aqueous- system preservatives available.

- High water solubility

Because spoilage microorganisms must have water for metabolic processes, they will thrive only in the aqueous phase of a formulation. DOWICIL 75 Preservative is highly soluble in water.

- Wide pH latitude

Most microorganisms require an environment with a pH between 5 and 9. The anti-microbial activity of DOWICIL 75 has been demonstrated in formulations with a pH ranging from 2 to 12.5.

The E.P.A. registration number of DOWICIL 75 Preservative is 464-403.
