UV Coatings

Two researchers in a laboratory
Focusing on coatings industry needs, we organize professional innovation workshops, develop new products in joint projects and offer technical support. Additionally our internet-based coatings barometer gives you an up-to-date impression of sentiment in the coatings industry.
UV-curable coating technology provides benefits in terms of good performance, environmental compatibility and processing efficiency. Liquid forms of UV-curing systems are solvent-free, require low energy for curing, and are adaptable to most conventional coating methods. Employing either radical or cationic curing mechanisms, the crosslinking of these coatings is initiated by means of UV light.

UV-curable coating formulations are based on acrylated oligomers (mainly acrylic esters of polyesters, polyethers, polyurethanes and epoxy resins).

  • BASF offers multi-functional polyol intermediates for the manufacturing of UV-curable acrylic monomers and oligomers. In addition to O-vinyl compounds (e.g., vinyl ethers) used as reactive diluents, BASF also offers a range of N-vinyl compounds (e.g., N-Vinyl caprolactam) for UV-curable coatings.
