Non-aqueous dispersions (NADs) are micron and submicron structured polymer particles used for rheology control and to prevent crack propagation in automotive coatings. The materials are a key part of DuPont Performance Coatings (DPC) technology platform, and are expected to grow in importance as a means to reduce volatile organic content in solvent-borne coatings without increasing viscosity. In this way, they offer a route to environmentally friendly products which also require lower energy consumption during the curing stage.

非水分散体(NAD)是微米和亚微米的结构化聚合物颗粒，用于控制流变性和防止汽车涂料中的裂纹扩展。这些材料是杜邦高性能涂料(DPC)技术平台的关键组成部分，作为一种在不增加粘度的情况下降低溶剂型涂料中挥发性有机含量的手段，预计将变得越来越重要。通过这种方式，它们提供了一条生产环境友好型产品的途径，这些产品在固化阶段也需要较低的能源消耗。
