The matte gloss white topcoat with high hardness,stain resistance and excellent anti-yellowing resistance was developed by hydroxyl-type resin as the film-forming material,adding calcium carbonate,titanium dioxide,anti-settling agent,leveling agent,defoaming agent,dispersant and wetting agent.The effects of resin and titanium dioxide raw material selection,curing agent and UV absorber on the properties of polyurethane wood coatings were investigated.The results showed that the product not only had excellent physical and mechanical properties,but also had high cost performance,which could meet the needs of the general home improvement market.
