Laminating Systems

The Ampreg™ 3X Series replaces Gurit`s legacy range of wet laminating systems for the manufacture of large composite structures in the marine, wind and construction industries.

The comprehensive 3X Series portfolio comprises of a single range of low toxicity, blend-able Ampreg 3X hardeners that can be used in conjunction with the following resins:

  • Ampreg 30 Low viscosity Resin: replaces Ampreg 21
  • Ampreg 31 Drainage resistance Resin: replaces Ampreg 22
  • Ampreg 36 Premium Performance Resin: replaces Ampreg 26

Additional ancillary products including Thixotropic Pregel Resin and High Tg hardeners are also available.

Health and Safety Focus

The award winning Ampreg™ 3X Series laminating system has been reformulated to prioritise user health and safety through careful selection of base chemicals. The new low toxicity resin matrix is CMR, SVHC and AEP free* and the hardeners are classified as environmentally non-hazardous.

Light Reflective Technology As Standard

Ampreg 30 is available with LRT (Light Reflective Technology) as standard, which serves as a risk monitoring feature for the user and enables inspection of contamination by means of UV light. To learn more about Gurit® LRT technology, please refer to the respective data sheet.
