Aqueous polyurethane emulsions were made by prepolymer dispersing process. Then fumed silica was added to emulsions to get silica modiifed aqueous polyurethane coating agent. Performance of SiO2/PU coating agent containing various dosage of fumed silica was researched. The result showed that performance indicators of emulsions were improved after appropriate dosage of fumed silica was added.
