Apply Methods of Programs and Applications
The biocide DA-20 is especially suitable for controlling pulp and paper mill process water, Microbial growth in cooling towers, heat exchangers and air conditioning systems. It can also be used for short-term protection of industrial products such as polymer dispersions, pigments and mineral slurries and wax dispersions.
The normal use concentration is in the range of 0.05-0.5%, depending on the protection product and the environmental conditions to which it will be exposed.
compatible Sex
If DA-20 is added at the same time with other preservatives, there may be an interaction . In this case, therefore, a separate analytical check for the stability of the active substance is recommended.
Before use, DA-20 must not be diluted or mixed with other raw materials, which may May adversely affect the performance of the active agent. Before using DA-20, the material compatibility of the system should be checked individually, such as the corrosion resistance of storage, transportation and dosing equipment. Prolonged or permanent contact with stainless steel increases the risk of pitting corrosion. Therefore, it is preferable to use plastic material.
