Highly reactive aliphatic polyester resin with excellent low-temperature cure performance.
Low viscosity enables easy processing and good fiber wet-out in composite manufacturing.
Outstanding hydrolytic stability and resistance to yellowing under UV exposure.
Compatible with standard free-radical initiators and accelerators used in unsaturated polyester systems.
Designed for solvent-free formulations, supporting VOC-compliant coating and gel coat applications.
Fiberglass-reinforced plastic (FRP) tanks and vessels for chemical storage.
Marine gel coats requiring high gloss retention and weather resistance.
Wind turbine blade matrices demanding consistent mechanical performance and process reliability.
Transportation components including bus and rail interior panels with stringent fire-safety requirements.
