Solvay develops sustainable ECTFE coating system
By Mario Cywinski
Solvay waterborne Halar ECTFE coating system offers metal corrosion prevention applications for the chemical processing industry. The system has a high adhesion primer and topcoat and is applied using standard liquid spray equipment.
Waterborne Halar ECTFE liquid coating technology expands the range of end-use applications to those that are difficult to powder coat. It also provides an alternative protective metal coating option to corrosion resistant alloys (CRAs).
“Sustainability was the compelling motive and driving force leading to the significant research and technological development of Solvay’s new waterborne Halar ECTFE liquid coating system,” said Brian Baleno, global business development manager Industrial, Energy & Environment at Solvay’s Specialty Polymers global business unit. “The environmentally-friendly, ultra-low Volatile Organic Compounds (VOC) and Hazardous Air Pollutant (HAP)-free formulation helps meet stringent regulatory customer needs. Waterborne finishes provide greatly improved work environment conditions on the production line and for sprayers and can also help lower costs in relation to equipment clean-up which relies on water and inexpensive cleaning agents.”
The liquid coatings, can be used without primer, in a range of thicknesses to meet requirements for various service conditions. They can be applied to a range of substrates such as metals, glass, masonry, polymers and wood. It has high chemical resistance, is hydrophobic with l resistance to strong acids and bases (pH 1-14) and is not affected solvents up to 150°C.
