CHEMEON Surface Technology’s (Minden, Nev.) CHEMEON eTCP RTU (Enhanced Trivalent Chrome Pre/Post Treatment Ready to Use) conversion coating and anodic seal has met the qualification requirements for MIL-DTL-81706 Type II, Class 1A and 3, Form III, Methods A, B and C for spray, brush and immersion methods. This means CHEMEON eTCP RTU joins the Qualified Products List (QPL) under QPL-81706 and is qualified for use as a Type II, Class 1A and 3 conversion coating under MIL-DTL-5541 in accordance with MIL-DTL-81706 and QPL-81706.
The company says its formula provides superior corrosion protection and adhesion to light metals such as 2024 aluminum, making it well-suited for the skin of aircraft, vehicles and parts. CHEMEON also promises environmental benefits and energy savings when using it as an anodic seal. Another key feature of eTCP RTU is its distinct color, which signals a successful coating process to quality assurance and quality control. CHEMEON’s eTCP suite of chemistries are REACH, RoHS, WEEE, and SVHC compliant.
“CHEMEON eTCP is designed to replace the known carcinogen hexavalent chrome and its identifiable yellow/gold hue with the violet/blue hue of CHEMEON eTCP,” says Madylon Meiling, CEO of CHEMEON. “We developed the CHEMEON eTCP technology as a safe, non-carcinogenic trivalent chromium conversion coating and anodic seal.”
This coating rose from a collaboration between CHEMEON and the Naval Air Systems Command (NAVAIR) Fleet Readiness Center Southeast (FRCSE) under a Navy Environmental Sustainability Development to Integration (NESDI) Project #514 NCRADA-FRSCE-17-001 cooperative research and development agreement to implement the patented eTCP from CHEMEON.
Dr. Sjon Westre, CHEMEON senior vice president of Technology and eTCP co-inventor, speaks highly of eTCP’s noticeable color indicator, noting the inability to determine coating application success with previous hexavalent chrome substitutes led to wasting resources on rerunning batches.
