There's nothing like a velvet 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.


GENOMER* 7287 – the provider of "soft" solutions for your challenges

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. It works wonders utilizing only small amounts of an aerogel silica and matting agent to produce a respectable soft touch and low gloss while maintaining excellent scratch resistance.

See what GENOMER* 7287 can do for you in terms of soft touch and reduced gloss performance. It's a hard world out there. Any opportunity to add a bit of velvety softness to it is a beautiful thing!

Flexibility + hardness = toughness = GENOMER* 4277

Are you a 3D printing formulator looking for that magical combination? This aliphatic urethane dimethacrylate may be the answer to your search. When used alone, the viscosity is unprintable by conventional VAT 3D, but mechanical properties are impressive. When formulated into a 3D printing resin with a workable viscosity, it offers excellent, versatile performance based on loading.


In a hard 3D resin formula, it can achieve properties that approach "the gold standard" for UV 3D printing resins – ABS performance. Yet, formulated into a flexible 3D resin, the toughness that

GENOMER* 4277 offers can result in a tough, flexible product with high elongation and work (area under the stress/strain curve). GENOMER* 4277 exhibits both low shrinkage and exotherm during cure, making it an outstanding oligomer for bringing toughness to your 3D printing resin.
