Abstract: Gypsum paper is treated with a mixture of a silanol containing organopolysiloxane polymer where the polymer has a viscosity varying from 1,000 to 1,000,000 centipoise at 25.degree. C. and in which there is mixed a liquid suspension of colloidal silica.

Abstract: A silicone emulsion for treating silicate particulate matter such as perlite and vermiculite, to make it water-resistant comprising a silicone fluid composed of difunctional siloxy units, trifunctional siloxy units and monofunctional siloxy units and as the emulsifier in water there is the reaction product of an aliphatic carboxylic acid with ammonia. The silicone emulsion is applied by spraying it on to the heated silicate particulate matter which is preferably heated to at least 150.degree. C., such that the silicone fluid rapidly cures on the particulate matter.

Abstract: There is provided a new improved two-part method of preparing an emulsified organosilicon-based, aqueous antifoam composition which comprises mixing thickened water (Part II) with a dispersion of an organosilicon antifoam agent and emulsifiers in water (Part I). The readily dilutable compositions provide economic advantages in manufacture, such as increased equipment utilization efficiency.

Abstract: There are provided antifoam compositions comprising a dimethylpolysiloxane and a precipitated silica reacted with hexamethyldisilazane and a process for the preparation and use thereof.

Abstract: A new and improved method of making aqueous, emulsified antifoam compositions is provided in which a silicone oil, a silazane-treated silica filler and emulsifiers are used. The technique permits the silicone oil and silica filler to be added to the composition, independently and directly, and thus avoids the need for first making an antifoam compound of these ingredients.
