Urethane Oil Uses

Urethane oil is a component of some finishes and coatings.


Urethane oil is obtained when combining a polyol, such as traditional linseed oil, with isocyanate, a molecule that contains nitrogen, carbon and oxygen. Urethane oil is mostly used in wood coatings. Other applications include use as a sealant in dentistry and in the production of microporous membranes and textiles.


Wood Coating


Urethane oils are better than traditional varnishes because they are more resistant to chemicals and scratches. These oils are also slower to yellow or amber. Adding pigments to urethane oils help to reduce the damaging effects of UV radiation that occur over time. Urethane oils also reduce microorganism growth on wooden surfaces constantly exposed to the elements, such as garden furniture.


Textile Industry


Urethane oil is used in the creation of fibers and synthetic membranes with specific properties, such as solvent, water and ultraviolet (UV) radiation resistance, as well as soil repellance, according to Dr. Katia Lacasse in "Textile Chemicals: Environmental Data and Facts." Urethane oil is also used to make microporous membranes and films used in wound dressings.


Dentistry


Dental sealants can contain urethane, according to dentist Dr.Naim Karazivan in "Applicator and Method For Applying a Sealing Agent on Smooth Dental Surface." Dental sealants are substances applied to teeth to prevent and stop the decaying process. According to Dr. Karazivan, the areas between teeth are more likely to suffer bacteria action, thus the importance of dental sealants applicator in the shape of strips or tapes.
