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.

Non-yellowing low VOC mineral surface enhancer

An inorganic matrix building material with enhanced water impermeability is prepared by curing an inorganic curable matrix and at least one particulate hydrophobic silicone resin substantially uniformly incorporated within the matrix, the at least one hydrophobic silicone resin being selected from the group consisting of a TD resin, an MQ resin, an MT resin, an MQT resin, and combinations thereof. In certain particular instances, the at least one hydrophobic silicone resin is a TD resin. The curing takes place at elevated temperature, optionally at elevated pressure.

Building materials incorporated with hydrophobic silicone resin(s)

In at least one embodiment, the present invention relates to a gypsum composition suitable for use in the manufacture of construction materials comprising a) gypsum, b) water, and c) a water repellancy composition comprising a hydroxy-based cellulose and a siliconate.
