Abstract: The present disclosure provides an orthodontic article including the reaction product of the polymerizable composition. Further, the present disclosure provides polymerizable compositions and methods of making an orthodontic article. The method includes obtaining a polymerizable composition and selectively curing the polymerizable composition to form an orthodontic article. Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying an orthodontic article; and generating, with the manufacturing device by an additive manufacturing process, the orthodontic article based on the digital object. A system is also provided, including a display that displays a 3D model of an orthodontic article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of an orthodontic article.

Abstract: A curable composition that includes a urethane multifunctional (meth)acrylate, an inorganic filler having a primary particle dimension of at least 200 nm, a photoinitiator system that can be activated by electromagnetic radiation in the range of 340-550 nm, a reactive diluent, and a reinforcing silica having a primary particle dimension of 100 nm of less. The sum of the absolute value of the difference in the refractive index of the filler and the refractive index of the composition cured without filler plus the birefringence of the filler is 0.054 or less, i.e. 0.054≥|nfiller−nmatrix|+δfiller, where nfiller is the refractive index of the filler, nmatrix is the refractive index of the composition cured without filler, and δfiller is the birefringence of the filler.

Abstract: A vehicle sensor system is described comprising an exterior surface; and a repellent composition disposed on the exterior surface, wherein the repellent composition exhibits an increase in haze according to the Dirty Water Spray Test of less than 5, 4, 3, or 2%. In typical embodiments, the repellent composition exhibits an advancing water contact angle from 90° to 125°. In some embodiments, the sensor system comprises a camera, a laser, a LIDAR sensor, a sonar sensor, or a radar sensor. The exterior surface is typically a windshield surface, a protective housing, or a lens surface. In some favored embodiments, the repellent composition exhibits a roll-off angle of no greater than 25, 20, 15, 10 or 5 degrees. Also described is a protective film, a repellent composition, a coating composition, and a method of evaluating repellency
