Overview

ACTICIDE® PDR is a premium dry-film preservative developed by Thor, specifically formulated for long-term protection of coatings, sealants, and construction materials exposed to challenging outdoor environments. It is based on a combination of isothiazolinone derivatives (DCOIT) and other stabilizers, providing robust defense against fungal and algal growth on coated surfaces. ACTICIDE® PDR offers superior leach resistance and UV stability, ensuring active ingredients remain within the film for sustained protection. Ideal for architectural coatings, textured finishes, and roofing applications, this preservative maintains aesthetic quality and structural integrity under severe moisture, temperature, and weathering conditions.
