    摘要: 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.
