VAE emulsion is a cornerstone in modern construction for its versatile performance. In tile adhesives, it enhances bond strength to concrete, ceramic, and stone, with peel strength ≥5 N/mm, resisting shear forces from heavy tiles. VAE-modified grouts gain flexibility, preventing cracks in bathroom floors subject to moisture and movement. For self-leveling compounds, VAE emulsion improves flow and compactness, ensuring smooth surfaces for flooring installation. Exterior wall coatings with VAE emulsion exhibit excellent weather resistance, maintaining color and integrity after 1,000+ hours of UV exposure. In cement modification, VAE emulsion increases mortar flexibility and crack resistance, ideal for facade renderings. Additionally, VAE-based sealants and caulks form elastic barriers in joints, withstanding 500+ freeze-thaw cycles, and low-VOC VAE formulations meet green building standards like LEED and China’s GB/T 35601.
