is now Dow’s exclusive supply channel partner. DCOIT has a very good microbiological spectrum,
Akcros says, a very low water solubility of just 2 ppm, and has good UV stability, especially compared to OBPA. This makes it quite suitable for exterior applications. Akcros offers the Intercide DBF family of products based upon DCOIT, including a range of pelletized masterbatch products. Almost all biocides can react with other ingredients
Zones of inhibition achieved with Akcros Intercide
the agar is put on the sample, rather than the other way around, would eliminate the zone of inhibition and produce more valid results that better characterize the growth of the bacteria on the sample itself. Akcros Chemicals, which has supplied OBPA, says that in the short- to medium-term it is working with its customers on alternatives while supplying them with their regular products during the expected transition from formulated OBPA products (its Intercide ABF family) to the more environmentally acceptable alternatives. According to Akcros, OIT is a good fungicide and is
generally more cost-effective pro-rata than similar isothiazolinones for interior uses. However, its relatively high water solubility makes it less suitable for exterior applications. Akcros now offers OIT-based biocide (Intercide OBF
family) as liquids and pelletized masterbatches globally. This follows a partnership with Dow Microbial Control in which Dow no longer supplies or produces biocides to the plastics sector; its Vinyzene brand has been incorporated under the Akcros Intercide banner. Akcros
in a PVC formulation, says Dean Nichols, European biocides product manager for Akcros. By far the most critical of these is the mixed metal stabilizer, also part of a range of products produced by the company. Nichols says that, by examining the antagonism between isothiazolinones and stabilizers over the last few years, Akcros has built up a bank of knowledge and experience which has led to the development of new stabilizers which provide a marked improvement in compatibility and performance.
