AL 1590 TCP TRIVALENT CHROMATE CONVERSION COATING ON ALUMINIUM AND ALUMINIUM ALLOYS

Physical Properties:
AL 1590 TCP: Liquid

Description

AL 1590 TCP is a liquid trivalent chrome passivation for aluminium and aluminium alloys. It produces iridescent to visible layer.

AL 1590 TCP can be used either in spray or immersion applications.

AL 1590 TCP has excellent bare corrosion protection comparable to hexavalent passivation. SST result on wrought Aluminium 800 ~ 1000 hours and for casting Aluminium 200 ~ 300 hours.

AL 1590 TCP is also suitable for spray paint or powder coating applications.
