Raprex 400 coatings are modified linear low-density polyethylene (LLDPE) or high-density polyethylene (HDPE) powders that can be applied to steel, aluminum, copper and other metals via standard powder-coating technologies. While polyethylene normally exhibits poor bonding strength to metal, Raprex 400 coatings use a proprietary process that imparts improved adhesion and coating characteristics to the base polyethylene, through oxidation, without the addition of chemical additives or a metallocene catalyst. Requiring no chemical pretreatment of the substrate, the coatings provide excellent corrosion protection, toughness and abrasion resistance in a variety of end uses.
