Application information

Preventol® D 7 is a microbicide containing a mixture of (1.5 % active) isothiazolinones. Preventol® D 7 has a broad specturm of activity, is water soluble and compatible with most raw materials. Preventol® D 7 will not adversely affect product physical properties or performance and should not impart odor or color to most final products. Preventol® D 7 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 Preventol® D 7 has a low viscosity, the product can be added directly or pre-dissolved in water.
Preservation
Preventol® D 7 provides broad-spectrum microorganism control in water-based systems. Preventol® D 7 is non-foaming, water-based product that is readily biodegradable after appropriate dilution.
Water Treatment
Preventol® D 7 is effective against bacteria that cause fouling and corrosion in industrial cooling water systems. Not only is Preventol® D 7 effective in controlling planktonic organisms, but the product will also aid in the control. 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 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.
 

Material Compatibility
Preventol® D 7 is compatible with high quality stainless steel. Compatibility tests are recommended for other metallic materials. Plastic materials like PVC, PE, HDPE, PTFE are compatible and suitable for the handling and storage of Preventol® D 7. As with any product, use of the products mentioned in this publication in a given application must be tested (including field testing, etc.) by the user in advance to determine suitability.
