LOW GLOSS, HIGH SOLIDS POLYUREA COATINGS

摘要

A method of forming a low gloss, high solids polyurea coating containing very low volatile organic compounds (VOC) in the coating composition. The low volatile content not only makes the coating environmentally friendly but allows it to be applied at variable thickness levels and over a wide variety of environmental conditions. The coating composition is comprised of an isocyanate reactive agent containing a secondary diamine, a polyisocyanate, a gloss reducing agent and a viscosity modifier. The gloss reducing agent is generally pre-mixed into an isocyanate reactive agent containing a secondary diamine and/or polyisocyanate containing the viscosity modifier before mixing the two components together to form a low gloss polyurea coating.
