Autodeposition composition of epoxy resin, nco crosslinking agent and crosslinker

摘要: Autodeposition compositions for polymeric coatings of reduced gloss are prepared using resins having at least one hydroxy group and epoxy per molecule, a low temperature crosslinker high crosslinker. The forms reactive prepolymer that may be subsequently mixed or emulsified with to form an autodeposition composition. Alternatively, hybrid crosslinking agent utilized which contains both free isocyanate groups relatively the resin functional capable reacting only elevated temperature. When deposited cured, resulting coating has matte finish is resistant surface defects.
