摘要： Polyurethane composites having improved dimensional stability and methods of manufacturing are described herein. The composites can include (a) a polyurethane formed by the reaction of (i) one or more isocyanates selected from the group consisting of diisocyanates, polyisocyanates, and mixtures thereof, and (ii) one or more polyols in the presence of a fatty acid, a fatty acid salt, or a combination thereof; and (b) an inorganic filler. The one or more polyols and the fatty acid mixture are not pre-reacted prior to reacting with the one or more isocyanates. The filler can be present in an amount of from greater than 50% to 90% by weight, based on the total weight of the polyurethane composite. The fatty acid, the fatty acid salt, or the combination can be present in an amount of from 0.05% to 10% by weight, based on the total weight of the composite.

摘要： Dust suppression agents and methods of use, e.g., to reduce operator exposure to particulate matter released during machining of a material, are described. The method may include providing a retained dust suppression agent proximate to a surface of the material and machining the material at the surface with a tool having a mechanized motion. The mechanized motion of the tool may release at least a portion of the retained dust suppression agent to reduce operator exposure to respirable particulate matter from the material as compared to machining the material at the surface absent the retained dust suppression agent.
