Description

T20-60 is a two-part low viscosity epoxy infusion resin developed for mass CFRP production. The resin offers simple and flexible processing due to low viscosity and room temperature impregnation. T20-60 was developed specially for vacuum infusion molding, to produce laminates with low porosity and optimal mechanical performance. It shows the following features and properties:


  • Two-part resin system for vacuum infusion and RTM
  • Wide processing window > 2 hours at 25°C
  • Curing at room temperature
  • Low exotherm
  • High crack resistance
  • Optimal price/quality ratio
  • Diese Materialdaten wurden von Matmatch zur Verfügung gestellt

    Processing methods

    Mix the components A and B and weight proportion 100:32. Degas the resin with intensive mixing for 15-20 minutes at 20-25°С. Maintaining resin pot temperature of 20-25°С and tool temperature of 20-25°С, begin resin infusion. Cure at room temperature for 24h. Make sure the resin is gelled. Remove auxiliary materials. Increase temperature at rate 0,5-2°С/min to 80°С. Postcure at 80°С for 3-6h.
