LOW-VISCOUS, RADIATION CURABLE FORMULATION, PARTICULARLY FOR THE STEREOLITHOGRAPHICAL PRODUCTION OF EARPIECES |
摘要 |
The invention relates to a biocompatible, low-viscous, radiation curable formulation, particularly for use in stereolithography, for use in medical technology, in particular, for producing earpieces, containing: a) 55-95 % by weight of a monomeric or oligomeric dimethacrylate based on bisphenol A or bisphenol F; b) 0-20 % by weight of a urethane methacrylate having a functionality of n < 4 and a viscosity < 15 Pa s; c) 2-15 % by weight of a monomeric aliphatic or cycloaliphatic dimethacrylate having a viscosity < 5 Pa s; d) 0-15 % by weight of a monofunctional methacrylate having a viscosity < 3 Pa s; e) 0.5-6 % by weight of a photoinitiator or a combination of a number of photoinitiators whose absorption is located within the wavelength range of the laser beam used; f) 0.0001- 2 % by weight of the inhibitor 2,2,6,6-tetramethylpiperidin-1-yloxy (free radical), also in conjunction with known inhibitors; g) 0-40 % by weight of fillers; h) 0-5 % by weight of coloring pigments; i) 0-5 % by weight of remaining additives such as UV stabilizers or spreading additives, whereby the proportions of constituents a) to h) total 100 % by weight. |
