CHEMEON eTCP® is worldwide the only MIL-DTL qualified replacement for hexavalent chromium (CrVI, Cr6+). eTCP is a completely unique product that provides a visual color indicator that your parts are surface treated and protected.
The lack of color has been a major barrier to the implementation of trivalent chromium, as a replacement for the old chemical hexavalent chromium. With the ground-breaking product eTCP®, significant problems with quality control and waste of resources are no longer present.
With the development of eTCP® and MIL-DTL qualification, a sustainable and innovative technology has been created for global aerospace, military and OEM customers.
CHEMEON Surface Technology eTCP®, is a safe corrosion protection that has been approved to MIL-DTL-5541F and MIL-DTL-81706B for use as a conversion coating on all aluminum alloys and other light metals.
CHEMEON's MIL-SPEC chemistry is REACH, RoHS, WEEE and SVHC compliant.
Yellow chromating is a chromium (VI)-containing chromating layer for aluminum components – also known under the trade names Alodine or Iridite.
The yellow chromating process is a chemical surface treatment that preserves and adds technical properties to the surface.
Yellow Chromation is a passivation method that uses Hexavalent chromium to give the aluminum certain technical properties in terms of conductivity, corrosion protection and adhesion.
This is referred to as a conversion coating, because the surface treatment changes the original properties of the aluminum.
Yellow chromated objects get, as the name suggests, a yellow/golden glow after treatment.
SurTec 650 TCP (Trivalent chromium passivation) was developed by Naviair in collaboration with the US Defense Force. SurTec 650 TCP is an alternative to the chromium (VI)-containing chromating of aluminum components. The SurTec 650 TCP process is a chemical surface treatment that adds new chemical and technical properties to the surface.
SurTec 650 TCP, colloquially TCP, is a passivation method using Trivalent Chromium. SurTec 650 TCP exists as an alternative to Hexavalent chromium treatments.
SurTec 650 TCP is also a conversion coating, as it changes the properties of the aluminium.
SurTec 650 TCP takes on a blue-green iridescent sheen, but appears very transparent.
HAI® TCP complies with the requirements of MIL-PRF-8625, Type II/ Class 1A and 3
The Enhanced Trivalent Chrome Process (eTCP®), an invention of CHEMEON®, is an extraordinary technological advance that is revolutionizing surface treatment processes. eTCP Powder, Ready To Use (RTU) and Touch-Up Pen are QPL (Qualified Product List) approved to MIL-DTL 81706B, MIL-DTL 5541F, TT-C-490 Type VI for immersion, spray, brush, wipe and touch -up pen. eTCP® is a highly effective and environmentally friendly solution used at room temperature to prepare metal surfaces for various applications, providing exceptional corrosion resistance, adhesion and improving material durability.
At its core, patented eTCP® uses environmentally safe trivalent chromium compounds and a color of violet to indicate that parts are fully coated and protected. The visual color indicator distinguishes eTCP® from all other MIL-DTL trivalent compounds and the traditional yellow-gold hue associated with hexavalent chromium. Hex Chrome has faced increased scrutiny in the United States and abroad due to its established health risks. Many industries and regulatory bodies have implemented stricter regulations and guidelines to reduce or eliminate the use of hexavalent chromium and encourage the use of safer alternatives such as eTCP®.
eTCP® not only delivers superior performance on 2024 aluminum and other light metals, but also provides a visual color indicator that is of tremendous value for part quality control (QC) and quality assurance (QA). The switch to eTCP® also addresses critical environmental and health concerns associated with older hexavalent chromium-based chemistries known as sodium dichromate, potassium dichromate, chromic acid, diluted chromium, CrVI and marketed under brand names that have included Alodine and Iridite.
One of the most compelling aspects of CHEMEON eTCP® lies in its ability to form a protective coating on metal surfaces through a chemical conversion process. This coating acts as a shield against corrosion, provides superior adhesion to traditional paints and ARC paints, significantly extending the life of metal components and structures in harsh environments such as marine or industrial environments. By preventing oxidation and degradation, eTCP® ensures the long-term integrity and reliability of materials, reduces maintenance costs and improves operational efficiency.
In addition to its outstanding performance and environmental benefits, eTCP® also offers ease of use and compatibility with legacy and existing manufacturing processes. This adaptability allows for seamless integration into different production lines, ensuring a smooth transition and cost-effective implementation.
Furthermore, eTCP's environmentally friendly nature is a major highlight. By eliminating the use of the familiar hexavalent chromium, eTCP® minimizes the risk of environmental contamination and protects the health of workers involved in the surface treatment process. This innovation is in line with sustainability goals, making eTCP® an ideal choice for industries committed to reducing their ecological footprint.
Overall, the enhanced Trivalent Chrome Process (eTCP®) represents a game-changing invention from CHEMEON® that combines cutting-edge technology, environmental responsibility and uncompromising performance. With its ability to provide exceptional corrosion resistance, improve material durability and promote sustainability, eTCP® sets a new standard in surface treatment, making it an invaluable asset to industries worldwide.
