摘要：
A biocompatible, low viscosity, radiation-hardenable composition for production of antimicrobial medical products, especially adaptive ear pieces by positive-negative-positive (PNP) or generative processes, contains specified amounts of urethane methacrylate(s), (di)methacrylates, antimicrobials, photoinitiator(s), anaerobic inhibitor(s), fillers, colorants and other additives. A biocompatible, low viscosity, radiation-hardenable composition for production of antimicrobial medical products, especially adaptive ear pieces by positive-negative-positive (PNP) or generative processes, contains by weight (A) monomeric/oligomeric urethane methacrylate(s) of functionality below 4, viscosity below 30 Pa.s and molecular weight below 3500 (0-75%) (B) a monomeric/oligomeric dimethacrylate based on bisphenol A or F and/or a monomeric (cyclo)aliphatic di(meth)acrylate of viscosity below 6 Pa.s (0-45%) (C) crosslinked monomeric or oligomeric component(s) with >=3 (meth)acrylate functions (0-25%) (D) monofunctional (meth)acrylate(s) (0-15%) (E) a combination of antimicrobial glass fillers or silver particles (0.01-5%) (F) photoinitiator(s) absorbing in the wavelengths of the laser radiation or other radiation source (0.5-6%) (G) anaerobic inhibitor(s) (0-0.5%) (H) fillers (0-10%) (I) colorants (0-5%) and (J) conventional additives such as UV stabilizers or processing aids (0-5%).
