G/flex from West Systems is a tough but flexible epoxy resin system that, unlike conventional epoxy resins, can be used to bond plastics. This makes it suitable for installing the plastic rims of rubber deck hatches used in some wooden kayaks such as the stitch-and-glue Petrel, as well as many other applications.
We are currently selling these g/flex repair kits at a discount (normal price £29.23) because its ‘use by’ date is October 2016.
The epoxy adhesive is prethickened and mixes at a 1:1 ratio for convenience. It is ideal for permanent waterproof bonding of dissimilar materials including plastic, fibreglass, ceramics, metals and even damp woods. It bonds to HDPE, LDPE, ABS, PVC and polycarbonate plastic.
