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.

If this is the challenge confronting you, RAHN may have help for you. Low viscosity GENOMER* 7287 combined with the correct choice of fillers can bring this problem to a very "soft" conclusion.
