TCP-HF is certified to meet QPL listing to the new DTL-81706B specification for NON-hex chemical conversion coatings, including all requirements Type 2 A 1 C, Type 2 B 1 C, Type 2 A 1 A, and Type 2 B 1 A. Additionally, this coating meets all requirements for both the ELV (End of life vehicle) and WEEE (Waste Electrical and Electronic Equipment) Directives.

Metalast TCP-HF Background
TCP-HF is a trivalent based coating aimed at replacing Hexavalent Chromates. Hexavalent Chromates have been banned in the automotive world as well as carcinogen and all other industries are quickly following suit.

Department of Defense, United States Navy developed and tested
TCP-HF was developed and patented by the Department of Defense, U.S. Navy after existing coating replacements failed to qualify for Navy use due to high cost and inferior performance.

TCP-HF Performance
TCP-HF outperforms all other trivalent products tested by a magnitude of two to three times the corrosion protection, coating durability, paint and adhesive bonding, and, at a cost comparable to hexavalent chromates.

The product was developed for use on aluminum but has been tested and proven effective on a variety of metals including zinc, zinc alloy, and cadmium. TCP-HF is user friendly, applies at room temperature with no odor and a pH close to neutral.

TCP-HF Field Testing
The Navy tested the product on entire airframes of the F/A-18 as well as on the tail sections of the S-3. The aircraft were flown for an extended period with excellent long-term results.

The product has also been tested and approved for use on the Exterior framework of the United States Army Amphibious assault vehicle being manufactured by General Dynamics at GDDS Virginia.

TCP-HF Comparison
Of twenty competitive products tested by dozens of independent companies, TCP-HF outperformed all competitors by nearly twice the neutral salt spray corrosion testing.
