HAPA

High Adhesion Polymer Alloy (HAPA) plastic coating powders have been specifically designed to provide a long lasting, chemically & mechanically tough coating for both exterior and interior applications. HAPA coatings are a superior choice when compared to the conventionally used PVC and Polyester Coatings. The Coating has excellent adhesion to the base metal and is almost impossible to peel off. We have following grades on the basis of applications - 

  • HAPA for Welded Wire Mesh
  • HAPA for Fire Extinguisher
  • HAPA for Valve
  • HAPA for Spring
  • HAPA for Cable Ties
  • HAPA for Battery Boxes
  • HAPA for Water Proofing

Coating

 Hot substrate dipped in the  fluidized tank full of powder where  the powder is fluidizing when the  pressurized air blown from bottom  to top. The substrate will  completely dip in the powder.

 Electrostatically charged powder blown on  the hot substrate from your regular spray  coating gun.

 HAPA powder blown inside the flame to the  substrate. The powder melts in transit and  forms a solid coating as the substrate cools  down.

 Fix the nozzle of the gun on the top  of the rotating fire extinguisher and  spray the powder inside the  extinguisher.

 Fill the powder inside the bottle or  cylinder and then the cylinder will  spin and tumble so that the cylinder  can be coated uniformly. The left  out powder removed out of the  cylinder.
