Polyphase® 663
  
				
				Broad-spectrum dry-film preservative particularly useful where VOCs are a concern
				
               Polyphase 663 is a broad-spectrum, water-based dry-film preservative that is effective against a wide variety of fungal and algal organisms. This product is particularly useful in water-based products in which Volatile Organic Compounds (VOCs) are a major concern and more than fungal protection is desired. It is particularly effective for application over cementitious substrates.
