The radiation curing technology, part of the allnex portfolio, is characterized by an energy-efficient profile along with a portfolio of low- to no-VOC products. The technology uses energy-induced radical polymerization, which results in immediate curing of the coating that can be achieved with ultraviolet light or electron beams. Alternative curing mechanisms can be obtained in combination with peroxides and/or in the presence of elevated temperatures. Read More… Because of its performance, high throughput and sustainable profile, this technology is widely used in markets such as industrial wood, packaging, inks and plastic coatings. The replacement of less environmentally friendly technologies, such as solvent-based and acid-catalyzed systems that release volatile organic compounds into the atmosphere, has contributed to the growth rate and interest in this technology. In particular, this shift has affected industrial wood coatings such as furniture and flooring, a trend driven by brand owners and actively supported by allnex. While radiation curing already offers a sustainable profile, allnex is continually  pushing the boundaries to further reduce its environmental footprint by investing in more efficient production processes, increasing the durability of its products and continuing to develop a portfolio of resins that contain safer chemicals and incorporate bio-based building blocks to ultimately reduce its overall carbon footprint. One of these efforts led to the development of EBECRYL®4690, a bio-based energy curable aliphatic urethane acrylate. This one-of-a-kind, patented product contains 30% C14 (measured according to  ASTM D6866) and is tin, solvent and BPA-free. The product combines excellent weathering resistance, high reactivity, a strong abrasion and chemical resistance with a very low yellowing. It is therefore ideal  for both clear and pigmented coatings for exterior and interior applications, as well as for coatings for furniture, kitchen cabinets, floors and panels. The carbon footprint reduction of the material can be estimated as >500 g CO2/kg. When developing the product, allnex considered other key market elements such as […]
