Functional Materials
Polyester resins have good mechanical properties such as flexibility, impact resistance and abrasion resistance. They also have excellent build and appearance, and are used in a various applications such as construction, wood working, steel sheets, PCM (Pre-Coating Metal) coatings and adhesives.
Condensation resins are manufactured from the reaction of polyol and polybasic acid and they possess polyester bonds on the main chain.
For coatings, condensation resins are classified into alkyd resins containing natural oils and fatty acids and oil-free alkyd resins with only a polyester structure.
Condensation resins are used for various types of coatings including ambient temperature drying, forced drying, baking, and two-component urethane curing. DIC offers polyester/alkyd resins that have achieved high functionality through modification with other resins such as acrylics, urethanes, epoxies, phenols and silicones.
What is Polyester / Alkyd Resins?
DIC's Advantages
Major Applications
DIC's Polyester / Alkyd Resins
-
Alkyd Resins for Ambient Temperature Drying Coatings
Alkyd resins are formed by the condensation reaction of oil or fatty acid, acid and polyol. They are used in various applications and materials. In particular, medium and long-oil alkyd resins and modified alkyd resins can form strong films when dried with a dryer.
-
Alkyd Resins for Thermosetting
Short oil alkyd resins are typically used as binders for coatings and printing inks. For lacquers in particular, they are used in combination with nitro cellulose (NC) or cellulose acetate butylate (CAB), which have excellent drying properties.
-
Powder Polyester Resins for Coatings
FINEDIC products are polyester resins for powder coatings that do not contain organic solvents or water. FINEDIC are highly regarded as environmentally-friendly because they do not release VOCs when forming forming coating films and they can be recovered and reused.
-
Waterborne Polyester / Alkyd Resins for Coatings
WATERSOL products are self-emulsifying type waterborne resins with ionic hydrophilic groups chemically introduced into the resin structures. They exhibit excellent film-forming properties and outstanding pigment dispersibilities.
-
Polyester Polyols
DIC has a long record with the fundamental technologies that support the expansion of urethane resin applications for coatings, adhesives, and elastomers. DIC's polyester polyols for raw materials of polyurethane have high quality.
