Abstract: This paper discussed the dosing process of Nanos4000-2 Nano silica concentrate in coatings, and analyzed the influence of Nanos4000-2 Nano silica concentrate on performance of epoxy coatings and polyurethane coatings through a series of tests of Nanos4000-2 Nano silica concentrate in epoxy coatings and polyurethane coatings. Studies have shown that Nanos4000-2 Nano silica concentrate could be completely dispersed in epoxy coatings and polyurethane coatings when grinding before let down process. The coatings modified by Nanos4000-2 Nano silica concentrate have shown significantly improved corrosion resistance wear resistance, hardness and little gloss reduction.
