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.

Case Study

Baltic 67 Performance cruiser

Baltic Yachts drew on their 48 years of design and building experience to create a full composite boat, with a glass hull and full carbon deck. Using Gurit epoxy SPRINT™ and Corecell™ M foam, Baltic were able to produce a strong, lightweight structure with a significant performance edge.
