UV-Curable Soft-Touch Coatings

Sartomer's new acrylate oligomers optimize UV-curable soft-touch ink and coatings formulations by allowing instant curing and enhanced durability. These soft-touch oligomers give UV-cured coatings the high-end luxurious feel and appearance of a rubbery, velvety or silky surface. They allow formulators to tailor their coatings to fit their specific needs, combining desirable feel effects and improved coating resistance against abrasion, stains and chemicals.

 

Traditionally, rigid substrates have been coated with a 2K system that imparts excellent feel but lacks desirable physical characteristics like pencil hardness and resistance. Sartomer’s acrylate oligomers deliver improved durability over the standard 2K system without decreasing soft-touch feel quality.

 

The quick UV curing process of soft-touch coatings formulated with Sartomer's oligomers produces fewer VOCs and uses less energy than conventional techniques, making it more environmentally friendly than traditional two-part urethane systems. This instant curing capability also requires significantly less production time.

100% solids based UV Soft-Touch gives improved properties over standard 2k polyurethane coatings

These advanced products for UV-curable soft-touch coatings enable formulators to achieve performance propertiessuch as:

 

  • Durability
  • Range of Haptic sensations
  • Infinite pot-life
  • No Free isocyanate
