What are the differences between water-based and oil-based polyurethane for furniture finishes?
Water-based polyurethane is a more environmentally friendly option that dries faster, has less odor, and is easier to clean up. Oil-based polyurethane provides a more durable finish, with a richer color and higher level of protection against scratches and heat.
What are the differences between polyurethane oil and water-based polyurethane finishes for wood surfaces?
Polyurethane oil finishes are oil-based and provide a warm, amber tone to wood surfaces. They are durable and offer good protection against water and heat. Water-based polyurethane finishes, on the other hand, are water-based and dry clear, maintaining the natural color of the wood. They have a faster drying time, lower odor, and are easier to clean up.
What is the difference between a polyurethane PU coating and a thermoplastic polyurethane TPU coating?
A thermoset is a material that cures or sets into a given shape, generally through the application of heat. A cured, thermoset material will not remelt or otherwise regain the processibility it had before being cured. Curing changes the material forever. A thermoplastic material softens (becomes pliable and plastic) when heated, but it does not cure or set. It can be reheated to be reformed.
