How does it feel?

Soft touch coatings are unique finishes that deliver the feel and appearance of a rubbery, velvety or silky fabric substrate:

As much as aesthetic, the feel plays a decisive role in "buy or don't buy" decisions for consumer goods. Soft touch coatings are now extensively used in high-end applications like:

 

  • Automotive
  • Consumer electronics
  • Cosmetic packaging
  • Small domestic appliances
  • Printing special effects
