Abstract
Treating compositions for application to particles of a filler consist of 5-95 percent by weight of a silicon atom containing hydrophobic-type treating agent, and 5-95 percent by weight of a silicon atom containing functional-type treating agent, based on the weight of the composition. Useful functional-type treating agents include bis(alkoxysilylalkyl)polysulfides and mercaptoorganosilicon compounds. Useful hydrophobic-type treating agents include polyorganohydrogensiloxanes and silanol terminated silicone oligomers. The filler most preferred is precipitated (i.e., synthetic) calcium carbonate.
