AnoChem TCP replaces hexavalent aztm conversion coatings used for aluminum alloys without sacrificing corrosion resistance, electrical contact resistance or organic topcoat adhesion properties while meeting regulatory requirements of ROHS, WEEE and ELV legislation.

These, in conjunction with its superior cleaning process and statistical process control, have given Anoplate the edge with optimizing and being able to certify its AnoChem TCP coating for Class 3 applications.
