Talc for pitch control

The sixth and seventh steps involve treatment of certain talcs. Some talc grades are silane surface-treated for the rubber industry. Others are treated with glycol stearate to improve dispersibUity and processing. Amine-coated talcs are used for fertilizers and cationic talcs for pitch control in papermaking. The surface treatment also helps vrith compatibihzation reactions of certain components of polymer blends [1, 4].
