25mm 300g Black Aramid Flat Braid (Seam Tape)

Predominantly used for the exterior seam on composite kayaks and canoes, the 25mm braid is woven from a 1210 dtex black aramid yarn, directly equivalent to Kevlar (the Dupont brand name for aramid fibre). The fibre is woven in such a way that the braid is 'flat', i.e. it is not a tube/sleeve but instead resembles a densely woven tape. The fibre orientation of the tape is +/- 45 degrees which means that the braid is ideally suited to handling torsional loads, affords excellent conformity (drape) without buckling the fibres and resists crack propagation.

Aramid flat braid is used as a very high strength wear resistant tape for joining or protecting joins in composite panels, most commonly around the seam of performance kayaks and canoes.

The black 25mm braid is ideal for repairing or replacing old/damaged seam tape found on the high wear areas such as the nose and tail of a kayak or canoe. Alternatively, our 17mm Black Aramid Flat Braid is ideal for more discrete reinforcement and adding a protective edge to composite paddles.

The braid should be wet-out with resin such as our EL2 Laminating Epoxy or ER1 Rapid Repair Epoxy and if required, over-coated with another coat of resin to create tough, durable protection to more vulnerable/high wear areas.

Aramid flat braid is compatible with all conventional resin systems including polyester, vinylester and epoxy resin. Most commonly, the braid is applied to the outside seam of canoes and kayaks to completely overlap the join between the upper and lower hull mouldings. The braid is then simply wet-out with epoxy resin and then once cured, over-painted once more with another coat of epoxy resin to create an extremely tough, durable and protective join.
