The hardness and impact resistance of water-based paint need to be balanced in terms of performance. This is because they have different importance and functions in coating applications.

Water-based paint typically utilizes polymer resins, such as acrylic resin, as the base. When balancing hardness and impact resistance, paint manufacturers need to consider the characteristics of the resin system and the formulation of additives. Increasing the crosslink density of the resin and the dosage of hardeners can enhance the hardness of the coating but may reduce its impact resistance. Conversely, the use of plasticizers or toughening agents can improve impact resistance while potentially lowering hardness.

In practical applications, paint manufacturers and coating experts balance hardness and impact resistance based on specific needs and application scenarios. Certain paint systems may also enhance impact resistance by introducing particulate fillers into the coating while maintaining high hardness.

In summary, balancing the hardness and impact resistance of water-based paint is done to achieve optimal coating performance and protection in different application scenarios.

The typical hardness of conventional water-based amino baking paint film ranges from 2H to 4H. However, in certain specific application environments, water-based paint may require a hardness of up to 5H and an impact resistance of 50cm without cracking. To meet customer requirements, the DCA Additive Application Center has developed a water-based baking paint formulation (180°C) that achieves high hardness and impact resistance using existing market raw materials.
