Biresin CR122 Epoxy Resin
Name: Biresin CR122 Epoxy Resin. Brand: Biresin. Category: Chemistry > Adhesives. CR122 is a medium-viscosity epoxy resin specifically developed for manufacturing high-strength composite products that operate at elevated temperatures up to 120°C. The material possesses optimal rheological properties, ensuring excellent fiber wetting and uniform impregnation, making it suitable for complex technological processes in industrial production.
Applications
- Production of composite parts using vacuum infusion or hand lay-up methods.
- Manufacturing of tooling and molds.
- Use in the aerospace, automotive, and shipbuilding industries.
Key Advantages and Properties
- Excellent penetrating ability and low tendency to drain, ensuring high-quality fiber impregnation and minimizing defects.
- Certified by Germanischer Lloyd for use in industrial composites, confirming compliance with high quality standards.
- Glass transition temperature (Tg) up to 120°C depending on the curing regime and choice of hardener.
- Wide selection of hardeners with the same mixing ratio for adjusting curing time and achieving necessary technological parameters.
- Possibility of demolding after room temperature curing when using certain hardeners, simplifying technological cycles.
- High mechanical characteristics: tensile strength, flexural strength, and increased impact resistance of finished products.
