Fiberglass Rebar

For over 70 years Scott Bader has been developing and manufacturing vinyl ester, urethane acrylate and isophthalic resins for pultrusion and rebar applications. We’re proud to say that our vinyl ester technology is world renowned for producing durable, corrosion resistant fiberglass rebar in a cost and energy efficient way, offering advanced curing flexibility and high line speeds.

Fiberglass Or Steel Rebar?

Fibreglass rebar offers significant advantages over steel, here’s why:

Corrosion resistance

Fibreglass is inherently resistant to rust and chemical degradation, extending the lifespan of concrete structures in demanding environments.

Lightweight

Which means final structures are lighter-weight and handling costs are reduced.

Non-conductive

No electromagnetic interference so ideal for specialist uses such as electrical substations.

High tensile strength

At least comparable to steel, often superior ensuring structural integrity.

Scott Bader's High Performance Vinyl Ester Technology

Crystic VE671 is a premium vinyl ester resin engineered for high-performance rebar applications. Renowned for its exceptional curing properties and superior durability, Crystic VE671 stands as the resin of choice for industry professionals seeking high-performance, reliability and efficiency.

  • Advanced Curing Capabilities: Crystic VE671 is designed to cure effectively with industry-standard hot moulding catalysts. These catalysts are optimal for the pultrusion process, providing flexibility and efficiency in the manufacturing process.

  • Catalyst Flexibility: The curing temperatures and catalyst ratios of Crystic VE671 are flexible. Lower catalyst ratios necessitate higher curing temperatures, whilst higher catalyst ratios enable lower curing temperatures, offering flexible processing vs Epoxy.

  • Optimised Manufacturing Efficiency: Crystic VE671 can achieve typical line speeds of 3.5 meters per minute (mpm) with oven temperatures ranging from 150°C to 200°C. This efficiency ensures a streamlined production process, maximising output and reducing downtime.

  • Energy Efficiency: Crystic VE671 is more energy efficient compared with epoxys, providing significant value in terms of life cycle costs and a lower environmental footprint.

  • Corrosion Resistance: Extensive research has shown our high quality Crystic VE671 vinyl ester technology offers superior corrosion resistance when compared with other resin technologies, particularly in alkaline concrete environments. This characteristic is critical for end users focusing on long-term durability and life cycle performance.

  • Proven Performance: Crystic VE671 has undergone rigorous testing to ensure long-term durability. Industry leaders have set high standards, and Crystic VE671 has successfully met and exceeded these stringent criteria.
