Advances in water-resistant modification of aqueous acrylic resins: modification methods, mechanism of action

Waterborne acrylic resin is widely available in architectural coatings, road adhesives, etc. Its non-toxicity, non-irritating odour, and low cost are characteristics that have received increasing attention in recent years. Concerning the water-resistance of the resin, this review introduces the effect of inorganic materials like silane coupling agents, fluorine silicone, and copolymers on the hydrophobic properties of aqueous acrylic resins, analyses and discusses the mechanism of action of various methods and their factors affecting hydrophobic properties, such as the formation of cross-linked structures and micro-convex structures on the surface, also points out the problems and challenges in the water-resistance modification of aqueous acrylic resins.
