There are two characteristics of polycrylic making it more favorable over polyurethane - it's less toxic, and it dries quicker. While that’s true, the toxicity of water-based polyurethane is very also. Secondly, polyurethane doesn’t take too long to dry either and sometimes you can apply a new coat In just a few hours. When it comes to kitchen cabinets, you need to consider the color of your wood and the intent of use. Because of the constant heat and humidity, polyurethane is the best choice in the kitchen. It's far more durable than polycrylic and will preserve your cabinets longer. Even if you have light-colored cabinets, it's still best to use water-based polyurethane than polycrylic as it gives you a clear finish.
