FORTECOAT PTA Welding Powders for Plastic and Rubber Industry

In plastic and rubber industry, the PTA welding method minimizes the naturally occurring adhesive wear with twin-screw extruders and enormously increases the service life of the machines. Nickel, Cobalt- based alloy and Tungsten-carbide with nickel-matrix coatings are used for adhesion and corrosion resistance.
