Solid polyhydroxy polyether phosphate ester compositions

摘要

Synthesis of water-dispersible solid epoxy phosphate ester resins suitable for the formulation of zero VOC water-borne heat-curable coating systems which are unique to the coatings market. The solid epoxy phosphate ester resins which can be manufactured without any solvent being present can subsequently be used in solid form or molten form; or the resins can be molten and dispersed in water without the aid of an organic solvent or any other volatile coalescing agent. The solid epoxy phosphate ester resins can be used in ultralow VOC water-borne heat-curable coating systems or in powder coating applications.
