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
  • This material data has been provided by Matmatch.

    "Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
    All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
    Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.

    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.
