Features Of CVI TSC-1M-HI Toughener

  1. High-impact modification for epoxy and vinyl ester resins without compromising thermal stability.

  2. Reactive liquid polymer with excellent compatibility and low viscosity for easy incorporation into resin systems.

  3. Enables significant improvement in fracture toughness (KIC) and delamination resistance in cured composites.

  4. Halogen-free formulation supporting UL 94 V-0 rated flame-retardant composite designs.

  5. Stable shelf life of ≥12 months at room temperature under sealed, dry storage conditions.

Typical Applications Of CVI TSC-1M-HI Toughener

  1. Aerospace primary and secondary structural composites requiring damage-tolerant laminates.

  2. Wind turbine blade root and spar cap materials demanding high fatigue and impact performance.

  3. High-performance printed circuit board (PCB) prepregs for advanced IC substrates and 5G RF modules.

  4. Railway interior panels and automotive under-hood components meeting stringent fire-safety standards.

  5. Marine hull and deck laminates exposed to cyclic mechanical loading and moisture ingress.
