FSE 322 — Impregnating Epoxy
Two-component, solvent-free epoxy resin engineered for saturating and bonding carbon fibre fabrics to concrete, masonry, steel, and timber substrates. The thixotropic formula enables vertical and overhead application without sagging, while its long 70-minute pot life allows comfortable working. Colour-coded, VOC-compliant components ensure correct mixing, and the moisture-tolerant formulation delivers reliable performance even on damp substrates.
