POLYPHASE 663

POLYPHASE 663 is an advanced broad-spectrum preservative that offers superior protection against micro-organisms for water-based materials. It provides excellent dry-film antifungal and anti-algal protection in exterior applications. POLYPHASE 663 was designed for aqueous systems, including alkyd and acrylic paints. It also provides protection against mildew and algal growth on sealants. Due to a high concentration of actives, POLYPHASE 663 is very cost-effective and offers long-term efficacy. It contains no alkylphenol-ethoxylates and does not chalk on exposure. POLYPHASE 663 has a broad spectrum of efficacy against fungi and algae. Suggested use levels should be verified by field trials. The actual level required for antimicrobial protection is formulation specific.
