Blue River Coatings Hyfro-Flex Polyurethane Top Coat
Categories: Polymer; Adhesive; Thermoset; Polyurethane, TS

Material Notes: BLUE RIVER COATINGS HYDRO-FLEX POLYURETHANE TOPCOAT is a water dispersible polyurethane. When the customer receives HYDRO-FLEX, it is already formed in the container, where as the solvent base type, the polyurethane is formed on the substrate. Therefore, once the paint is applied on the substrate, the film properties of HYDRO-FLEX rival that of other two component catalyzed systems. HYDRO-FLEX offers outstanding coverage, excellent durability, and ease of application as well as being a low VOC and EPA compliant coating.

Enviromental Advantages:BLUE RIVER COATINGS HYDRO-FLEX POLYURETHANE TOPCOAT is considered non-hazardous by EPA definitions and does not contain lead or chromates. The solid and semi-solid sludge produced in spraying and clean up can be flocculated; dried and sent to a “Class B” landfill. Check with local and state regulations for proper handling.

Characteristics:

  • Excellent exterior durability
