| Résumé : |
Polyurethane as a coating medium was introduced in 1950s and has since then gained ground in terms of application. This is because of the high performance one gets from such coatings such as improved chemical and solvent resistance, mar resistance, weather resistance etc. The paper deals with the fundamentals of polyurethane -- its starting raw materials, the polyurethane reaction including kinetics of reaction and the different types of polyurethane coatings commonly used. A small section has also been dedicated to the water borne two pack polyurethane. |
