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.
