Hexavalent Chromium Free Conversion Coating
TCP-HF Conversion Coating™ matches or exceeds properties of conventional Cr(6) conversion coatings, including bare (unpainted) corrosion protection.
TCP-HF Conversion Coating™ offers the following advantages:
• Replacement for conventional hexavalent chromate conversion
• Environmentally safe (compliant with RoHS, ELV and WEEE directives
• Meets or exceeds MIL-C 5541 for bare (unpainted) corrosion resistance
• Low contact resistance: meets electrical conductivity requirements on aluminum substrates, per MIL-C 5541 class 3
• Meets paint adhesion requirements per MIL-C 5541 Sur faces treated with the TCP-HP Conversion Coating™ process are generally a faint blue to tan and iridescent.
