Abstract (en)
[origin: WO9615179A2] The invention relates to radiation curable compositions for molding both rigid and flexible medical, orthodontic and other articles. The present invention broadly encompasses pourable liquid compositions which are radiation curable to form rigid or flexible articles. Uses of the compositions include medical devices, flexible or rigid prostheses, dental and orthodontic applications, model-making, and even industrial parts. In its broadest aspects, the compositions of the present invention include as the primary component acrylic-functional polyurethane resin(s), diluent monomers to dilute the composition to the desired consistency, photosensitizers, synergistic reducing agents, lubricants, thickeners, reinforcing fillers and pigments, as needed for the particular application. These components are present in suitable proportions so as to achieve the desired results in terms of physical properties (i.e., strength, hardness, etc.).
