English 
Alkyd resin is an important coating resin, mainly composed of condensation and polymerization of polyols, polyacids and fatty acids or oils (triglyceride fatty acid esters). The structural characteristics of this resin are polyester as the main chain and the side chains are unsaturated long chains, which have good adhesion, wear resistance, weather resistance and insulation.
Main classification of
dry alkyd resins: can be cured in air and is suitable for self-drying or low-temperature drying.
Non-dry alkyd resin: It needs to be mixed with amino resin and heated to cure.
Oil: According to the content of fatty acids or oils used, it is divided into four types: long, medium, short and extremely short.
Characteristics and application
Ultra-fast drying characteristics: For example, G26 water-based alkyd resin can achieve surface drying within 30 minutes, suitable for furniture manufacturing, automotive parts coating, etc.
High hardness: Provides excellent wear resistance and scratch resistance, suitable for high-frequency use of furniture surfaces and industrial equipment in harsh environments.
High gloss paint film: The average brightness can reach 98%, suitable for high-end furniture, electronic product shells and decorative metal products.
Excellent water resistance: Excellent in humid or watery environments, suitable for bathroom furniture, outdoor facilities and marine equipment.
Salt spray resistance: Excellent in salt spray erosion of more than 500 hours, suitable for extreme environments such as marine engineering, coastal buildings and automotive parts.
Modification technology
Blend modification: By blending with other polymers, the drying speed, hardness and water resistance of the coating film are improved.
Chemical modification: Introduce other molecules, such as epoxy or acid anhydride, through chemical synthesis pathways, enhancing the weather resistance and mechanical properties of the coating.
Environmental protection and efficient
water-based: As a water-based coating, it reduces the emission of volatile organic compounds (VOCs) and reduces the harm to the environment and the human body.
Efficient drying and long-lasting protection: Help users reduce resource waste, improve production efficiency, and achieve the dual goals of environmental protection and efficiency.
To sum up, alkyd resins have an important position in the coatings industry with their excellent physical properties and wide applicability. With the advancement of technology and the enhancement of environmental awareness, their application prospects will be broader.
