Urethane acrylates are a special kind of polymer that are made by combining isocyanates with acrylate monomers that have hydroxyl groups. They are widely used as coatings that can cure quickly under UV light for various purposes, such as industrial, automotive, packaging, and plastic coatings. Urethane acrylates have several advantages over other kinds of UV curable coatings, such as:

Fast curing: Urethane acrylates can harden quickly under UV light, even with low energy sources such as LED lamps. This reduces the time and energy needed for curing, and improves the productivity and efficiency of the coating process.
High quality: Urethane acrylates can achieve excellent mechanical, chemical, and outdoor properties after curing. They can provide high scratch resistance, high flexibility, high hardness, high gloss, and excellent adhesion to various substrates . They can also resist yellowing, fading, and degradation caused by UV exposure and weathering.
High flexibility: Urethane acrylates can be modified by changing the structure and composition of the isocyanate and acrylate components. This allows for custom-made formulations that can meet the specific requirements and preferences of different applications and customers. For example, urethane acrylates can be mixed with other resins, such as epoxy acrylates or polyester acrylates, to improve certain properties or reduce costs. They can also be added with various additives, such as pigments, fillers, stabilizers, or antimicrobial agents, to enhance the functionality or aesthetics of the coatings .

Urethane acrylates are a promising class of UV curable coatings that can offer superior quality and sustainability for a wide range of applications. They are expected to grow in demand and popularity in the future as more customers seek for high-quality and eco-friendly coating solutions.
