This is a high-quality water-based emulsion of a special acrylic-styrene copolymer resin. Use it to enhance the adhesion of self-leveling materials and prevent the formation of air bubbles. It is quick-drying, allowing you to proceed to the next step quickly. Air bubble formation is suppressed. It has excellent alkali resistance, water resistance, and weather resistance. Dilute to the specified ratio before use (for application only).
