Procedure

Stearic acid (75 grams) was added to 500 gram of zinc clay RA. The mixture was attrition milled for two hours and then heated at 150° C. for one more hour. The product again was attrition milled and then jet milled through a CJ-10 jet mill manufactured by Nisshin Engineering Co. Ltd. of Japan. The final product was sieved through a 200 mesh sieve to produce zinc stearate clay RB. There is some loss of material through dusting at the various milling processes. Its properties are listed below:
