Halogen Free Flame Retardant Manufacturer

Fireproof Coating

In homes, office and public buildings, if there is the building material without protection, once breaking out of fire, the building material such as steel structures, metal sheets, wood, plaster and concrete will gradually lose intensity and become easy to collapse. However, if these building material are coated with special coating, then the heat would be blocked, which will lengthen the survival time.  

Presafer high polymerization ammonium polyphosphate (EPFR-APP series) can provide protection for these building materials. Compound with acrylic resin/epoxy resin/polyurethane resin, EPFR-APP series can be used to make the ultra-thin intumescent fire-proofing coating, and in this respect, presafer has rich experiences, which can help customer to figure out the special solution in a cost-saving and efficient way, and meet the fire protection requirements and achieve other regulation.
