Hyperbranched polymers as UV curable reactive diluents has good application
Hyperbranched polymer’s branched chain contains a lot of functional groups, with higher molecular weight, low volatility, slight toxicity and irritation to the human body. And hyperbranched polymer has low viscosity properties, therefore, low viscosity hyperbranched photosensitive prepolymer as reactive diluent has become a new development direction. Hyperbranched polyurethane acrylate not only has a great activity but also won’t occur oxygen inhibition , the coating structure between crosslinking points has different soft segments and high crosslinking density to make the coating both hard and tough, and has good solvent resistance.
