Modification of Polishing Putty: A Study on Inorganic Filler

The microstructure of talcum powder added with the KH550、KH560 and silane composite coupling agent were studied by atomic force microscope, the modified effect of KH560 coupling agent was the best, which verified through the microstructure analysis and the wetting contact Angle proved law method. The relationship between the dosage of KH560 coupling agent and contact angle was analyzed by the wetting contact Angle proved law method. The optimum dosage of KH560 coupling agent was determined by the experimental results of the viscosity of polishing putty.
