ST 160

OUT OF AUTOCLAVE SPRINT™ TECHNOLOGY
  • Ideal for structural out of autoclave applications
  • Excellent handling, drape and mould conformance
  • Fast lay-up times

Gurit’s innovative SPRINT™ product range uses a high flow, low tack epoxy prepreg ideally suited to the manufacture of thick sections.

ST 160 SPRINT™ technology can be cured using compression moulding or vacuum bag processing and offers a flexible cure envelope of just 15 minutes at 165°C. This unique product provides technically and commercially competitive engineering materials, ideal for use either solely, or in conjunction with other Gurit products from within the range.

Typical Applications
