Alkyd Resin - Long Oil

Brief Overview Alkyd resin, is a complex oil-modified polyester that is widely used in a variety of fields involving paints and coatings industry, woodworking, construction, steel sheets, and adhesives. It has strong mechanical properties and has a good resistance against impact, flex, wear and tear. Depending on the length and its method of polymerization, alkyd resins have various properties: different degrees of film-forming, adhesions, and resistance against external factors.   Manufacturing Process Alkyd resins can be produced in two stages. In the first stage, vegetable and pentaerythritol are heated with catalyst under the temperature of 270°C for 2 hours. In the second stage, after cooling down to 150°C, phthalic anhydride is added and heated with mixture to 240°C to get polyester alkyd resins. The product is obtained after the removal of water via evaporation.
