What is the Difference Between Polyurethane Urethane and Varathane?

The terms polyurethane, urethane, and varathane sound similar but have different meanings and applications. Here are the key differences between these terms:

Polyurethane: Polyurethane is a polymer material that is available in both water- and oil-based options. It is used in various applications, including as a wood finish, adhesive, and foam. When used as a wood finish, polyurethane provides a durable, hard, and transparent coating that allows the wood to show its natural beauty while offering protection.
Urethane: Urethane is the chemical linkage that forms when an isocyanate reacts with a hydroxyl or amine compound. It is not a wood stain but is a component found in many polyurethane products.
Varathane: Varathane is a brand name for a type of wood stain that is water-based and provides a clear, hard, scratch-resistant finish on hardwood surfaces. It is not a polymer like polyurethane but rather a product designed to enhance the appearance and durability of wood surfaces.

In summary, polyurethane is a polymer material, urethane is a chemical linkage found in polyurethane products, and varathane is a branded wood stain. While both polyurethane and varathane can be used to finish wood surfaces, they serve different purposes and have different characteristics.

Comparative Table: Polyurethane Urethane vs Varathane

The main differences between polyurethane, urethane, and Varathane are their composition, properties, and applications. Here is a table summarizing their differences:

Feature	Polyurethane	Urethane	Varathane
Definition	Polyurethane is a polymer made from isocyanates and polyols, with repeating urethane linkages throughout the material.	Urethane is a chemical group found in polyurethane.	Varathane is a brand of wood stain and polyurethane finish.
Composition	Polyurethane is made up of organic units of isocyanates and polyols.	Urethane is a part of the polyurethane composition.	Varathane offers a range of wood stains and finishes, including water-based and oil-based products.
Properties	Polyurethane is rigid and firm.	Urethane is soft and malleable.	Varathane provides a clear, hardwood finish that is stain and scratch-resistant.
Applications	Polyurethane is used in various applications due to its durability and adaptability, such as furniture, bedding, flooring, and heavy-duty coatings.	Urethane is a part of polyurethane and contributes to its properties.	Varathane is used for interior wood projects, such as floors, doors, furniture, cabinets, trim, paneling, and railings.

Polyurethane and Varathane are both used to provide a good finish on wood surfaces, but polyurethane tends to offer a glossier finish, while Varathane focuses on bringing out the natural beauty of the wood.
