Chemical/Physical Properties
Synolite™ 8488-G-2 is a low-viscosity polyester resin. It is particularly recommended for vacuum-assisted resin injection molding.
Sales Regions
Not manufactured or sold in mainland China.
Main Applications
Synolite™ 8488-G-2 is particularly well-suited for marine applications.
Key Characteristics
Synolite™ 8488-G-2 is a DCPD-pre-accelerated unsaturated polyester resin based on styrene monomers. The resin is pre-accelerated.
Synolite™ 8488-G-2 enables the production of laminates with relatively short delamination times at excellent polymerization levels.
Synolite™ 8488-G-2 exhibits very low peak exothermic heat release.
Approval
Synolite™ 8488-G-2 is approved by Det Norske Veritas (DNV) for marine applications.
