There's Nothing Like a Velvety Soft Touch

Formulating a viable soft touch coating has consistently been an elusive target in energy-curing applications.  Soft feel is a very subjective property that is affected by a formulation's glass transition temperature and the specific fillers used to generate this coveted texture.  Typically, waxes improve the surface feel while silica-based matting agents combined with higher Tg acrylates increase smoothness and scratch resistance.  A balanced combination of the two surfaces can produce the desired haptic quality with good scratch resistance performance.

However, high inherent crosslinking and limited shrinkage (versus solvent-based coatings) make it challenging to formulate low gloss and soft feel energy-cured coatings. In addition, the high filler loading necessary to achieve soft touch can result in lack of good coating flow and poor scratch resistance.
