Oil-based, whose proper name is “oil-modified urethane,” is produced by reacting common finishing oils, like linseed oil, with a chemical that causes the oil to form larger molecules. A good rule of thumb is that larger molecules mean more durable finishes. The Characteristics of Oil- and Water-based Polyurethane.
Does oil modified polyurethane yellow?
Does oil modified polyurethane yellow? Oil modified polyurethanes are a mix of oil and water based poly. They tend to go on less yellow than an oil based poly but slightly more yellow than the high grade water based polyurethane such as Bona Traffic HD and Loba. They have a slightly amber tone.
Is water based polyurethane the same as Polycrylic?

Which is better oil based or water based spar urethane?
1. Oil based polyurethane looks better. It has a more depth – both in color and shine and it looks the way we expect hardwood to look. Water based polyurethane has both a duller color and a duller finish.
