Latent Acid Catalyst for Pultrusion Manufacturing

Pultrusion is a continuous process for manufacture of composite materials with constant cross-section. Reinforced fibres are pulled through a resin, possibly followed by a separate pre-forming system, and into a heated die, where the resin undergoes polymerization. Using CSR enabled resin within the process can bring significant benefits over other resin-based systems.

Some of the benefits gained from using CSR within pultrusion:

  • Increased line speed
  • Longer resin bath life/stability
  • No need for bath chilling
  • Reduced curing temperature

Recent customer feedback has reported 150% increase in process speed coupled with a 30°C reduction in curing temperature.
