Development of High Solid Acrylic Polyurethane Topcoat for South China Sea Environment
The effects of hydroxyl acrylic resins,polyester polyol resins,resin ratio,and P/B on the basic physical properties and weather resistance of the topcoat are explored,and a high solid acrylic polyurethane topcoat with high weather resistance suitable for the South China Sea environment is prepared.The research shows that the paint film has excellent weather resistance and mechanical properties when polyester polyol resin B2 is used as a modified resin to replace 20%hydroxyl acrylic resin A1 as the base material system,and P/B is controlled at 6/4,and the topcoat can meet the needs of various construction methods.
