Alkyd resins; in primary forms

HS v2022 Code: 390750

About alkyd resins; in primary forms

HS code 390750 covers alkyd resins, which are a type of synthetic resin widely used in the production of paints, coatings, and adhesives. Alkyd resins are an important component in the manufacturing of various industrial and consumer products, playing a crucial role in the broader chemical industry. Their versatility and desirable properties, such as fast drying, high gloss, and durability, make them indispensable in a range of applications across diverse sectors.

Production process

Alkyd resins are typically produced through a polycondensation reaction between polyhydric alcohols, such as glycerol or pentaerythritol, and polybasic acids, such as phthalic anhydride or maleic anhydride. The reaction is carried out under controlled temperature and pressure conditions, often with the addition of catalysts to optimize the process. The resulting alkyd resin is then further refined and processed to meet the specific requirements of its intended use.

Production inputs

The main inputs required for the production of alkyd resins include polyhydric alcohols, polybasic acids, and various additives such as drying agents, solvents, and modifiers. Additionally, specialized equipment, such as reactors, distillation columns, and mixing tanks, are necessary for the manufacturing process. The availability and quality of these raw materials and production equipment are crucial factors in the alkyd resin industry.

Production outputs

Alkyd resins produced under HS code 390750 are primarily used as binders in the formulation of paints, coatings, and varnishes. These resins are often combined with other materials, such as pigments, solvents, and drying agents, to create a wide range of paint and coating products. The outputs of this industry are then consumed by various downstream industries, including 321100 Paints and varnishes, 321200 Printing inks, and 325500 Adhesives, among others.
