Soft touch and feel UV coatings

Give a high-end luxurious feel to your UV curable specialty coatings

How does it feel?

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

acrylate monomer and oligomer resin for soft touch and feel UV curing coatings

 

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

 

acrylate monomer and oligomer resins for soft touch and feel UV curable coatings

Formulate soft touch UV coatings with PRO21615

PRO21615 is an aromatic urethane acrylate especially designed for UV curable soft touch coatings

Typical liquid properties:

  • Contains 25% butyl acetate as solvent
  • Viscosity @ 25°C: 1600 mPa.s
  • Color: 80 Apha
  • Form: clear to hazy liquid

 

Typical film properties:

  • High Persoz hardness
  • Good solvent resistance
  • Good stain resistance

 

acrylate monomer and oligomer resins for soft touch and feel UV curable coatings

Main features:

  • Spray applications
  • Can be formulated "as is", without additional resins, to obtain a solvent resistant "silky" coating
  • Can be formulated with CN9002 to obtain a "velvety" coating

The two formulations are applied on ABS panels with a target thickness of 36µm. The solvent was flashed off at 60°C / 5 minutes. The coatings were cured 3 x 10 m/min using a Mercury vapor 120W lamp. The panels exhibited a soft feel, characterized as “silky” and “velvety”, good adhesion on ABS (6x6 crosshatch) and good resistance to solvent.
