VAE emulsion is a cornerstone of water-based paints and coatings. In exterior paints, VAE emulsions provide weather resistance, withstanding 1,000+ hours of UV exposure without fading or chalking. They form flexible films (Tg -5 to 10°C) that expand with building movements, preventing cracks. In interior paints, VAE emulsions offer scrub resistance (≥5,000 cycles) and easy cleaning, ideal for high-traffic areas. For wood coatings, VAE emulsions enhance adhesion to timber, with peel strength ≥3 N/mm, while their water resistance protects against moisture damage. VAE-based primers bond to difficult substrates like glossy surfaces, improving topcoat adhesion. Additionally, VAE emulsions in industrial coatings provide corrosion resistance for metal substrates, combining durability with environmental friendliness.
