Alkyd resin is the result of the esterification reaction of a polyol and a polyacid and a monovalent fatty acid. In fact, alkyd resin is a polyester with a monovalent fatty acid in their structure. Alkyd resins dividing into three types of long oil, medium oil and short oil depending on the oil length and are used in various industries including construction paints, decorative paints, corrosion-resistant primers, varnishes and inks, furnace paints, automotive paints, etc.

Amino resins are etherified by Isobutyl alcohol and n-Butanol. They are used in manufacture of stoving paints along with non-air drying alkyd resins and some of epoxy resins, Nitro-cellulose resins, thermoset acrylics, saturated polyesters and acid drying coatings. In combination with air drying short oil alkyd resins, amino resins can also be used in wood industry.

Bakelite molding powder is produced from the combination of phenolic resins (Novolak) and additives such as soot, graphite and other fillers, and are used as electrical insulation in the electrical industry (production of lamp holders, electrical control parts, etc.) as well as Gas meter parts and home appliances.

Acrylic resins are the product of condensation polymerization of acrylic, methacrylic acids and their derivatives. The use of water based resins is one of the appropriate methods to reduce the amount of organic solvents consumed and as a result toxic volatile. Water based acrylic resins are used in paint, concrete, adhesion, textile industries, etc.

Saturated polyester resin is prepared from esterification reaction of poly acid with poly alcohol and is divided into two groups of liquid saturated polyester (solvent base) and solid saturated polyester. Solvent-based polyester resins are applied in coatings used on metal sheets, can coating, coil coating and automobile paints. They are also used in anti-corrosion coatings on iron- steel structures that have epoxy-based primers.

Epoxy resins are commonly the product of reaction between epichlorohydrin and bis-Phenol A. By increase in molecular weight and viscosity, they change from a low viscose liquid to a high viscose liquid and finally become solid. Solid epoxy resins are commonly manufactured in flake type, and generally used in production of powder coatings. They exhibit good chemical and mechanical resistance.

Solvent-based polyester resins have excellent characteristics, with a wide range of applications. They have high resistance to abrasion, impact and cracking. They are mostly applied in coatings used on metal sheets, can coating, coil coating and automobile paints. They are also used in anti-corrosion coatings on iron- steel structures that have epoxy-based primers.
