Features Of DSM Uralac SN847 Saturated Polyester Resin

  1. Excellent chemical resistance to solvents, acids, and alkalis in cured powder coatings.

  2. High glass transition temperature (Tg) enabling superior storage stability and reduced blocking tendency.

  3. Optimized for high-gloss, smooth film formation with excellent flow and leveling characteristics.

  4. Low melt viscosity ensures efficient electrostatic application and uniform film build on complex substrates.

  5. Compatible with standard TGIC and hydroxyalkylamide (HAA) curing agents for flexible formulation design.

Typical Applications Of DSM Uralac SN847 Saturated Polyester Resin

  1. Architectural aluminum extrusions requiring durable, weather-resistant finishes.

  2. Appliance housings and panels demanding high scratch and corrosion resistance.

  3. Office furniture and shelving systems requiring aesthetic consistency and mechanical robustness.

  4. Automotive non-structural components such as trim and under-hood parts.

  5. General industrial metal fabrication where long-term color and gloss retention are critical.
