Abstract

Low VOC mineral surface enhancer compositions are non-yellowing and contain a condensable aminoorgano-functional organopolysiloxane fluid, a condensable organopolysiloxane resin, and a condensation catalyst. The compositions provide a durable, color enhancing wet look to mineral surfaces to which they are applied.
