Chemical resistance of polyurethane – PUR.
Does polyurethane react with alcohol?
Polyurethane medical devices can be exposed to alcohols in day-to-day use. This exposure can be short, such as through simple wipe down, or can be prolonged, such as with complete immersion.
Will rubbing alcohol remove wood finish?

Does kerosene dissolve polyurethane?
PU are also resistant to diesel, kerosene and the FAM test fluid Fuel A (ASTM D 471), showing no loss of strength, and show limited resistance to Fuels B and C. … Water: Polyurethanes can remain in water at 20°.
What’s the difference between urethane and polyurethane?
There is no difference between the terms urethane and polyurethane. … The term polyurethane simply means that it contains multiple urethane groups. Polyurethane elastomers (urethane elastomers) are one type of a large family of elastic polymers called rubber.
How does vinegar remove varnish from wood?
