Thor's main expertise lies in the production and formulation of standard and customised biocides based on own manufactured actives including isothiazolinones (available from two major Thor sites), formaldehyde donors and IPBC.  A range of quaternary ammonium compounds is also amongst Thor manufactured biocides marketed under the international trademark ACTICIDE®.  These biocides prevent the biodeterioration of products both in their wet/fluid, dry/cured and intermediate states.
