Preventol® D 7 CF

• Preventol® D 7 CF is a copper-free formulation of isothiazolinones.
• Preventole D 7 CF is a microbicide containing a mixture of (1.5 % active) isothiazolinones.
• Preventol® D 7 CF has a broad specturm of activity, is water soluble and compatible with most raw materials.
• Preventol® D 7 CF will not adversely affect product physical properties or performance and should not impart odor or color to most final products.
• Preventol® D 7 CF is readily incorporated into formulation and is compatible with surfactants and emulsifiers regardless of their ionic nature.
• However, if higher temperatures (>104 °F / >40 C) or pH values >9 are likely to occur during the manufacturing process, the product should be added at the end of the process or to the finished product. In this case take care to distribute the preservative uniformly in order to ensure homogeneous mixture of the product in the water. Since the Preventole D 7 CF has a low viscosity, the product can be added directly or pre-dissolved in water.
• Preservation: Preventol® D 7 CF provides broad-spectrum microorganism control in water-based systems. Preventol® D 7 CF is non-foaming, water-based product that is readily biodegradable after appropriate dilution.
• Water Treatment Preventol® D 7 CF is effective against bacteria that cause fouling and corrosion in industrial cooling water systems. Not only is Preventol® D 7 CF effective in controlling planktonic organisms, but the product will also aid in the control of biofilms. Use of the appropriate level of biocide in the water system can help to maintain a sufficient water flow rate and heat exchange by reducing the microbial load in the system.
• Slime Prevention Preventol® D 7 CF is a broad spectrum bactericide including efficacy against slime forming bacteria. Slime forming bacteria are a major concern in industrial water systems because they can help with the formation of biofilms. The biocide can be added directly to the primary circuit, the machine chest or the headbox. If the system is extremely fouled, it is recommended that a shock treatment followed by a continuous at a lower dose rate. (See Direction for Use section for dosage levels) Badly fouled water systems should be cleaned prior to biocide treatment.
• To obtain reliable and reproducible results, homogeneous distribution in the materials to be protected must be ensured by taking suitable measures in production (stirring, agitating, etc.)
• As with any product, the use of this product must be tested (including field testing) prior to incorporating into finished product.

For industrial use as preservative to inhibit the growth of bacteria, fungi in aqueous compositions (including pesticide formulations), polymer emulsions, fountain solutions, inks and photoplate processing, paper mill process water, recirculating cooling water systems, recirculating electrodesposition systems, commercial photoprocessing systems.

It is a violation of Federal law to use this product in a manner inconsistent with its labelling. The following guidance is given as an approximation for each use pattern, but field-testing is recommended to achieve optimum effectiveness.

**For detailed dosage instructions see Preventol® D7 CF EPA Label.
***Not For Use in the State of California.
****Regardless of the means of incorporation of the biocide, the total concentration in the system should not exceed 2333 ppm Preventol® D7 CF.

• Preventol® D 7 CF should be stored in the original sealed package.
• Since Preventol® D 7 CF is an aqueous solution, appropriate measures should be taken to ensure temperature does not exceed 104 °F/ 40 °C and does not freeze during the transport and storage.
