Industrial Recirculating Closed Loop Water Cooling Systems: For the control of bacteria, algae and fungi, add WES 625 microbiocide to the reservoir, recirculating line or some other point in the system to insure uniform mixing. Initial Dose: When the system is noticeably fouled, apply 148 to 883 ppm WES 625 microbiocide (1.26 to 7.46 pounds or 19 to 113 fluid ounces of WES 625 per 1,000 gallons of water in the system). Repeat until control is achieved. Subsequent Dose: When microbial control is evident, add 35 to 219 ppm WES 625 microbiocide (0.3 to 1.86 pounds or 4.5 to 28 fluid ounces of WES 625 per 1,000 gallons of water in the system) weekly or as needed to maintain control. Badly fouled systems must be cleaned before treatment is begun.
Polymer Latex Preservation: WES 625 microbiocide is recommended for the control of bacteria and fungi in the manufacture and storage of synthetic and natural polymer latices including; styrene/butadiene; carboxylated styrene/butadiene; ethylene/vinyl acetate, and biopolymers intended for industrial use, such as xanthum gum, gum arabic, guar gum, protein-derived polymers, starches, and casein-derived polymer. Add 0.43-3.3 lbs. of WES 625 1.5% microbiocide (195 g – 1.5 kg) to each 1,000 lbs. (454 kg) of emulsion to provide 425 to 3,350 ppm product (6.25 to 50 ppm active isothiazolones). NOTE: To insure uniform mixing add WES 625 microbiocide to latex or solutions slowly with agitation. The actual concentrations required will depend upon such factors as the specific substance to be treated, frequency of repeated microbial contamination expected and level of protection required.
Adhesive and Tackifier Preservation: WES 625 microbiocide is recommended as an in-container preservative for the control of bacteria and fungi in water-soluble and water-dispersed adhesives such as animal glues, vegetable glues, natural rubber latices, polyvinyl acetate, styrene-butadiene, and acrylic latices. WES 625 microbiocide is recommended as a preservative for tackifiiers derived from resin and hydrocarbon resins. Add 0.43-1.65 lbs of WES 625 1.5% microbiocide (195 - 750 g) to each 1,000 lbs (454 kg) of fluid to provide 425 to 1,675 ppm product (6.25 to 25 ppm active isothiazolones).
Paint and Coatings Preservation: WES 625 microbiocide is recommended as an in-container preservative for the control of bacteria and fungi in water-based coatings such as paper and wood coatings and paints used for architectural product finishes, and special purpose coatings. Add 0.43 to 1.65 lbs. of WES 625 microbiocide (195 –750 g) to each 1000 lbs. (454 kg) of fluid to provide 425 to 1,675 ppm product (6.25 to 25 ppm active isothiazolones).
Building Material Preservation: WES 625 microbiocide is recommended as an in-container preservative for the control of bacteria and fungi in building material such as mastics, caulks, joint cement, spackling and grouting. Add 0.43 – 1.65 lbs. of WES 625 microbiocide (195 – 750 g) to each 1000 lbs. (454 kg) of fluid to provide 425 to 1,675 ppm product (6.25 to 25 ppm isothiazolones).
Dispersed Pigment Preservation: WES 625 microbiocide is recommended for the control of bacteria and fungi in the manufacture and storage of dispersed pigments such kaolin clay, montmorillite clay, titanium dioxide, calcium carbonate, calcium sulfate, barium sulfate, magnesium silicate, and kieselguhr used in paint and paper production. Add 0.43 – 1.65 lbs. of WES 625 microbiocide (195 750 g) to each 1000 lbs. (454 kg) of fluid to provide 425 to 1,675 ppm product (6.25 to 25 ppm active isothiazolones.)
Reverse Osmosis Systems: WES 625 may be used to control microbiological fouling in reverse osmosis systems used for process water and other non-potable applications. WES 625 should be fed to the membrane feedwater at a rate of 20-120 ppm (2.75-16.5 fluid ounces per 1000 gallons of water). The product should be added continuously for a time period of 1-24 hours, 1-7 days each week depending on the severity of the problem. For off-line cleaning, WES 625 should be added to provide a level of 100-400 ppm (13.75-55 fluid ounces per 1000 gallons) in the soak solution.
Commercial Photoprocessing System Preservation: WES 625 is recommended to prevent slime formation or accumulation in filters and ion exchange resin tanks or commercial photoprocessing systems. For the maintenance of a non-fouled system, use WES 625 at 32-64 fluid ounces (2.1 lbs. – 4.2 lbs.) per 1,000 gallons water in the system once weekly, or as needed, to maintain control of slime. For a noticeably fouled system, use an initial dose of 64 – 154 fluid ounces (4.2 lbs. – 10.1 lbs.) per 1,000 gallons water to be followed by subsequent maintenance dosage. A high dosage range and/or increased frequency of treatment may be required depending upon rate of dilution of preservative with makeup fluid, the nature and severity of contamination, level of control required, filtration effectiveness, system design, etc. The preservative should be dispensed into the final rinse or used water collection tank.
Conveyor Lubricants: WES 625 can be used to control microorganisms in water-based conveyor lubricants. WES 625 can either be added to the lubricant concentrate or can be added to the lubricant dilution of feed line using a chemical metering pump. In lubricant concentrates, WES 625 should be added at a level that will ensure a final use dilution of 200 - 1000 ppm of WES 625 (3-5 ppm active). When led to the lubricant dilution feed line, an initial metered dose of 50-126 fluid ounces of WES 625 per 1000 gallons of diluted conveyor lubricant is recommended until control is achieved. A subsequent metered dose of 26 – 126 fluid ounces per 1000 gallons should be made to maintain 3-15 ppm active WES 625 in the diluted conveyor lubricant.
