SR 1280

Epoxy resin

SR 1280

Product description:

Low-viscosity industrial epoxy resin for contact lamination, vacuum infusion, and hot production of composite structures.

The system is formulated without CMR components with careful selection of raw materials offering the lowest toxicity possible and improving health and safety of the user.

SD 477x hardeners:

DNV-GL certified system for shipbuilding TAK00001GV.
Infusion possible from 28 °C.
The very slow hardener SD 4771 and the very fast hardener SD 4775 are miscible in any proportion to adjust reactivity.

Hardener SZ 8525:

Hot cure production system allowing cycles of 10 minutes at 100 °C without the need for post-curing to achieve maximum performance
