Pokraskin The primary role of paints and coatings is to enhance appearance and protect the surface from environmental damage during their
service life. Paints and coatings are used for a myriad of applications, and hence their service environment and the degree of protection expected vary to a large extent. Since binders and resins are the actual film formers, their proper selection in formulation is very important. Depending upon the requirements of the final dry film properties, very careful selection of resins is required. In general, resins and binders used for coatings should have the following desirable properties.
• A high MW or capability of cross-linking (curing) after application of coatings
• Solubility in solvents or dispersible in water for efficient formulation, processing and application
• Capability of forming a continuous, adherent and uniform film after application of coatings
• Physical, thermo-mechanical and optical properties as required by coating applications
• Broad range of compatibility with different resins, cross-linkers, additives, solvents and water
• Good shelf-life under normal storage conditions
• Requirement for low or no VOCs for their processing or use in coatings
• Ability to offer paint and coatings products that are compliant to regulatory requirements
• Preferably made from sustainable resources
• Be cost competitive.
