摘要： A cartridge made of a material that does not to a significant extend absorb polar components from a dental composition stored therein. The force required to extrude a dental composition from the cartridge increases less over time in a cartridge of the invention than in a cartridge of the same configuration made of conventionally employed materials such as nylon-6.

摘要： Abrasive particles which are shaped abrasive particles each with an opening are described. The shaped abrasive particles are formed from alpha alumina and have a first face and a second face separated by a thickness t. The opening in each of the shaped abrasive particles can improve grinding performance by reducing the size of a resulting wear flat, can provide a reservoir for grinding aid, and can improve adhesion to a backing in a coated abrasive article.

摘要： A structured abrasive article includes a backing having a structured abrasive layer disposed on and secured thereto. The structured abrasive layer includes shaped abrasive composites that comprise abrasive particles and nonionic polyether surfactant dispersed in a crosslinked polymeric binder. The abrasive particles have a mean particle size of less than 10 micrometers. The nonionic polyether surfactant is not covalently bound to the crosslinked polymeric binder and is present in an amount of from 2.5 to 3.2 percent by weight based on a total weight of the shaped abrasive composites. The structured abrasive articles are useful for abrading a workpiece.

摘要： A method for making an abrasive article having at least two abrasive coatings having different abrasive natures. The abrasive natures can differ, for example, by abrasive particle size, abrasive particle type, abrasive particle shape, filler, surfactant, or coupling agent. In another embodiment, the abrasive article can be a structured abrasive article comprising abrasive composites. In another aspect of the invention, the article can have a coating having a single abrasive nature, where the composites comprising the coating are free of abrasive particles.
