Features Of Evonik TEGO AddBond LTW Polyester Resin

  1. Enables low-temperature curing of unsaturated polyester (UP) resins without compromising mechanical performance.

  2. Significantly reduces styrene emissions during processing due to optimized reactivity profile.

  3. Improves interfacial adhesion between resin matrix and glass/carbon fibers in reinforced composites.

  4. Enhances gel time control and pot life stability at ambient and mildly elevated temperatures.

  5. Compatible with standard free-radical initiators and conventional UP resin formulations.

Typical Applications Of Evonik TEGO AddBond LTW Polyester Resin

  1. Fiberglass-reinforced plastic (FRP) components for transportation interiors and body panels.

  2. Low-emission marine hulls and deck parts manufactured via open-mold or spray-up processes.

  3. Architectural cladding and façade elements requiring high surface quality and reduced VOC release.

  4. Industrial tanks and corrosion-resistant linings produced using ambient-cure techniques.

  5. Wind turbine blade subcomponents where energy-efficient, low-heat curing is critical.
