CRC  3.36  prevents  rust  and  corrosion  by  displacing and  sealing  out  moisture  and  by  forming  a  continuous protection barrier against water and oxygen.CRC 3.36 forms a thin, invisible film that never gets dry or brittle, and penetrates into the finest pores and cracks of the surface. It does not have to be removed before the metal is machined, welded, stamped or otherwise processed.CRC  3.36  protects  aluminium  (Anodised  or  Mill)  and copper  from  plaster  burn  and  concrete  burn.  It  prevents “finger printing”, its protective film prevents the corrosion action of the acids and oils left by human handling.CRC 3.36 protects magnesium sheet, plate, extrusions and die castings during shipment and storage by forming a thin protective barrier against all atmospheric conditions.
