摘要

Abstract of the DisclosureTwo-component polyol/polyisocyanate compositionespecially useful as an abrasion-, heat-, and corrosion-resistant automotive undercoating. The polyol componentcomprises glycerol, a polypropylene oxide glycol, and apolypropylene oxide triol. The polyisocyanate componentcomprises MDI (diphenylmethane-4,4'-diisocyanate), plu5 apoly(oxypropylene) glycol capped with MDI.
