WEST System G/flex Liquid Epoxy Kits

West System G/Flex liquid epoxy is a toughened, versatile adhesive designed for permanent, waterproof bonds on fiberglass, ceramics, glass, masonry, metals, plastics, damp and difficult-to-bond woods. G/flex epoxy is resilient enough to bond dissimilar materials and flexible enough to absorb the stress of expansion, contraction, shock and vibration.

Available in liquid and thickened formulations, liquid G Flex 650 is a two part (resin and hardener) mixed at a 1:1 ratio. G/flex 655 is also a two part epoxy adhesive, but contains a thickening agent.

Note: 8 Ounce G Flex 650 kits are available in 2 formats: as 4 ounce resin and 4 ounce hardener kits (650-8), or with accessories that include 2 mixing sticks, 2 syringes, 4 mixing cups, 406 Colloidal Silica, 1 pair gloves and 4 alcohol pads (part number 650-K).

    I holed my royalex canoe seal launching into a rock. I knew normal epoxy resins would be too stiff to last for a long time. Canoe shop owner suggested g-flex. I used 2 layers 6oz. fiberglass and the g-flex, repair done in the low 30's for temperature, certainly not ideal. Patch is holding well, and is not stiff like other resins.I like how this stuff flexes, and it's tough as well.

          Comments about WEST System G/flex Liquid Epoxy Kits:

          I am restoring a 1957 Century Arabian and have used many epoxy products. But West G Flex is simply the easiest to use and an excellent option when repairing original frame and hull components is the objective. For a classis lie this repairs are preferred to replacements and I can only do that with West G Flex. I have tried many epoxies from discount to expensive and this is just the best to work with.

                    I wanted a product that was flexible and has a good bond with dissimilar woods. I used Gflex with Ipe and bamboo backed bow. So far it has held up to about a 100 arrow launches. Time will tell.

                        I have an old wooden ketch. I glassed the decks with 105/206 and biaxial cloth with mat. The glass extended over the top of the stem 9end grain). After a year or so, the glass separated from the end grain. I removed the old glass, drilled some holes in the end grain, filled the hole, glassed over with several layers of cloth (Gflex os too thick to soak into biaxial). Three years and is still good.

                          I have three Pungo kayaks that were damaged from dragging them. The rudders were worn down and caused leaking. With kayak right side up, open the rear hatch, use 80g sandpaper to clean the surface inside and vacuum. Flip it upside down, clean the rudder area. Apply duct tape over the hole, flip right side up again, put a couple of small wood blocks to raise the front end angle so the epoxy settles and cures into the desired area. Pour a 50/50 mix of the epoxy into the back rudder area. The tape prevents leakage. Let dry overnight. Flip kayak over, use tape to reform the rudder creating a pocket for the epoxy. Set the angle again. Pour same 50/50 mix into pocket. Let dry overnight and you should be all set!

                                I used this epoxy to repair the hull of my 1/8 scale gas hydro rc boat, it had a major crack down one sponson & the center part of the hull! I just sanded the whole length of the damage, then let the epoxy set up for a while until it was thicker, then using a putty knife I filled the damage in completely with G-flex & it worked great! I never had any problems at all! this stuff works on all types of materials, is extremely strong, flexable, waterproof & shock resistant...what more could you ask for? HIGHLY RECCOMEMDED!
