Resins

Unsaturated Polyester Resins are engineered for reliable performance across FRP  applications, from everyday laminates to demanding industrial and railway  components. These resins combine consistent reactivity, controlled viscosity and good  wet–out to help fabricators achieve predictable mechanical properties and high-quality  surface finish. 

• General-purpose orthophthalic resins are ideal for cost-effective laminates where good strength, processability, and surface appearance are required. They are widely used for boats, panels, tanks, and consumer FRP parts, offering fast cure, good fibre wet-out, and compatibility with hand lay-up, spray-up, and basic closed-mould processes.
• Isophthalic & Process Resins Isophthalic resins

  VBR’s Isophthalic Resin range provides higher mechanical strength, improved hydrolytic stability, and better chemical and weather resistance compared with standard orthophthalic grades. As an Isophthalic resin supplier in Tamil Nadu, VBR offers resin solutions for pultrusion, RTM/infusion, closed-mould processes, and demanding industrial applications.

  Isophthalic Resin is also suitable for applications such as chemical storage tanks, industrial process equipment, and FRP components where enhanced corrosion resistance and long-term durability are required.

• Speciality & Fire-Retardant Resins

  For critical sectors such as rail and mass transit, VBR offers fire retardant polyester resin and vinylester systems designed for demanding FRP applications. These resin solutions are suitable for railway composites and applications where flame, smoke, and toxicity performance are important.

  VBR’s fire retardant resin for railway composites supports the production of lightweight and durable FRP components for transportation and infrastructure applications. Options also include roof-lite and other FR grades for translucent sheets and safety components.

• Chemical-Resistant & Specialty Resins
  For demanding chemical applications, VBR offers Bisphenol and Vinylester resin systems where enhanced chemical, thermal, and fatigue resistance is required. These solutions can be used for Isophthalic resin for chemical tanks, industrial process equipment, FRP tanks, and other corrosion-resistant applications.
• Food-Grade Resin
  For applications requiring resin systems suitable for food-related FRP products, VBR also offers food-grade resin solutions in Chennai, subject to application requirements and applicable regulatory specifications. Contact our technical team to identify the appropriate resin for your application.
