Get quotationAbout this product
VBR-4508 is an epoxy-base vinyl ester resin grade. Public VBR information lists VBR 4508 within its vinyl ester range, and published composite research describes it as a medium-reactivity Bisphenol-A-based vinyl ester used in composite laminates.
Applications
FRP tanks; pipes; chemical process equipment; marine components; industrial laminates; corrosion-resistant composites
Key features
Bisphenol-A-based vinyl ester family; high-performance composite matrix; improved chemical resistance versus standard polyester systems; suitable for FRP
Recommended use
Use with the matched accelerator, promoter, and MEKP system and process according to the current VBR TDS.
Not recommended for
Do not treat as equivalent to every polyester or novolac vinyl ester grade; confirm chemical and temperature resistance for the service.
Handling and safety
Use appropriate PPE and good ventilation. Follow the current manufacturer TDS/SDS for handling, storage, mixing, and disposal. Keep containers closed and away from incompatible materials and ignition sources where applicable.
