Polyphase 612 is a free flowing powder that provides broad-spectrum fungicidal protection in thermoplastic and composite material. Used to treat PVC and plastisol formulations, wood composites, rubber gaskets, PE foam, vinyl and urethane textile coatings to prevent the growth of fungal organisms in the finished article. Polyphase 612 should be added to the plasticizer for PVC and plastisol applications. For other applications, Polyphase 612 should be added to the resin or masterbatch. Prolonged exposure to temperatures > 200° C should be avoided. US EPA registration is pending.
