Construction technology of BD7021 super wear abrasion resistant slurry pump epoxy repair coatings:
1.Clean up and polish the pending-repair workpiece on the needing-repair part.
2.Configure BD426T special undercoat and brush coating on the pending-repair part,then wait for the primer curing.
3.Configure BD7021 slurry pump epoxy repairing super abrasion wear resistant coating and make it be coating on
the pending-repair part,knock on it to be compacted with rubber hammer,then trim the surface with special
rounding tools,make the surface be flat and smooth.
4.Curing for 24 hours.
