Unsaturated Polyester Resin (For Coating) Production Line

Unsaturated polyester resin is widely used in coatings, industrial protective coatings, and composite material surface coatings. Compared to structural resins, coating unsaturated polyester resins place greater emphasis on reaction control, molecular weight distribution stability, and finished product viscosity consistency, thus imposing higher requirements on production equipment and process design.

Applications Areas

• Industrial coating
• Anti-corrosion coating
• Decorative coating
• Functional coating material

Processing Characteristics of Unsaturated Polyester Resin for Coating

1. Precise temperature control is required during esterification and polycondensation reactions.
2. Strict requirements are placed on reaction time and conversion rate.
3. The finished product must maintain good leveling properties and storage stability.
4. Side reactions and gelation risks must be effectively controlled during production.
