Abstract
A method and a system for fabricating articles made from thermoset resins using an ionic mold release agent. The invention uses a mold having a metal oxide surface with enhanced mold release characteristics. The release agent is applied internally in the resin composition or externally on the metal oxide surface. The method includes providing a mold, forming a metal oxide surface on the mold, providing an ionic release agent, providing the acid or base conjugate of the release agent at the metal oxide surface, providing a thermoset resin in the mold, and curing the resin in the mold. A method of using float glass having a SnO enriched surface, wherein the method includes the steps of providing an ionic release agent externally to the tin oxide surface, is also disclosed.
