Thomas Swan are an established European manufacturer of TCMTB (2-(Thiocyanomethylthio) benzothiazole) and have been developing a range of biocide products under their Casacide brand for use in North America. The final product in this range, Casacide T100, was granted approval by the US Environmental Protection Agency on July 13.
‘There are huge opportunities for Casacide in North America', said Chuck Van Fleet of Swan Chemical Inc, the UK company's American subsidiary. ‘The market has not had a wide choice of suppliers and we come to the market with a 20-year track record of quality and expertise in this sector.'
Casacide is a well proven broad-spectrum biocide which is easy to handle, without any hydrocarbon solvents, and produces stable emulsions on dilution with water - including both acidic and mildly akali solutions. Swan offers Casacide T400 with 80% TCMTB, T200 with 30% and T100 with 10% TCMTB and 10% MBT (methylene bis(thiocyanate).
In the leather industry, Casacide is widely used during the tanning process to provide long-term protection against fungal attack. Swan has developed a blend of surface active agents which ensure excellent surface contact and penetration into a wide range of organic materials.
