特にイヤピースの立体リトグラフィー製造のための低粘度の放射線硬化可能な組成物
Document Type and Number:
Japanese Patent JP4251368
Kind Code:
B2
Abstract:
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.
