Hudco Formula 4020LB

Beaded Wearing Compound

HUDCO 4020 LB is a specially formulated wearing compound that contains high wear resistance beads in a strong, durable epoxy matrix that is reinforced with ballistic grade aramid fiber for added wear resistance.  The beads are made of a high wear resistance material.  Because the beads in 4020 are small in size, a greater exposure of the wear resistant bead material occurs. This results in improved wear resistance and material flow.

Typical Applications

HUDCO 4020 LB is excellent in a wide range of applications including chutes, screw conveyors, pneumatic conveying equipment, slurry pumps and other areas where high wear occurs.
