Production Information

 Urea

・Use for burr removal of resin , automotive paint removal , surface cleaning of high precision parts
・ Moderate hardness among polygonal (Sharp angle)resin-based materials such as Urea , Melamine , Polyester.
・Reduce damage toward workpiece
Polishing material made from urea resin. This will remove only deposits on surface without damaging the surface of high precision parts.
Ideal for automotive paint removal, surface cleaning of high precision parts, cleaning resin mold / rubber mold / die cast mold.

Main Application
Burr removal, deposits cleaning, paint removal, film removal
Applicable material (of workpieces)
Resin, metal, die cast
