In a significant move to enhance environmental sustainability and operational efficiency, Tomburn has completed the installation of a cutting-edge plant setup – completed during the second half of 2024.
This investment was driven by the regulatory changes under UK REACH (UK registration, evaluation, authorisation and restriction of chemicals), starting in September 2024 which banned the use of chromate-based pre-treatment systems.
After extensive research, Tomburn selected Chemetal’s X4707 system for aluminium and an Oxysilan system for other metals, both of which boast impressive industry track records.
Chemetal’s X4707 pre-treatment system is specifically designed for aluminium, offering exceptional corrosion resistance and enhanced adhesion for powder coatings. This ensures long-lasting finishes that withstand harsh environmental conditions. Meanwhile, the Oxysilan system, used for other metals, leverages silane-based technology to deliver superior performance and durability. Together, these systems provide a robust, environmentally friendly alternative to traditional chromate-based processes.
The shift to chrome-free pre-treatment represents a critical step forward for Tomburn, aligning its operations with modern sustainability goals while ensuring compliance with stringent environmental laws.
Initially, the new plant setup operated alongside the existing system, allowing Tomburn to validate its performance and achieve operational stability before fully transitioning. This cautious approach underscores the company’s commitment to maintaining high-quality standards throughout the whole powder coating process.
The adoption of chrome-free pre-treatment offers several key advantages:
1. Reduced environmental impact: Chrome-free systems eliminate the use of hexavalent chromium, a toxic pollutant, and significantly reduce hazardous waste. This contributes to cleaner water sources and ecosystems, aligning with global sustainability efforts.
2. Improved worker safety: By replacing hazardous chemicals with safer alternatives, chrome-free pre-treatments mitigate health risks such as respiratory issues and skin irritation. This creates a safer working environment while reducing the need for extensive protective equipment and complex ventilation systems.
3. Enhanced performance: Modern chrome-free systems, like Chemetal’s X4707 and Oxysilan, offer corrosion resistance and adhesion properties that rival or exceed traditional chromate-based processes. These qualities ensure durable and visually appealing finishes for architectural applications.
4. Operational efficiency: Chrome-free systems operate at lower temperatures and generate less sludge and waste, reducing energy consumption and maintenance costs. Simplified workflows also enhance production efficiency, minimising downtime.
5. Optimised processes: By separating aluminium from other metals during treatment, Tomburn ensures the aluminium process tank remains uncontaminated and in peak condition, further enhancing the quality of the finished product.
Architects, contractors, and developers are increasingly prioritising suppliers who demonstrate a commitment to sustainability and innovation. With its investment in chrome-free pre-treatment, Tomburn is well-positioned to meet the growing demand for environmentally friendly powder coated products. This forward-thinking approach not only ensures compliance with evolving regulations but also reinforces Tomburn’s reputation as a leader in the powder coating industry.
By embracing cutting-edge technologies, Tomburn continues to set new standards for excellence in architectural finishing solutions.
