Product Details

West System G/Flex epoxy resin is a toughened liquid adhesive designed for permanent, waterproof bonds on fiberglass, ceramics, glass, masonry, metals, plastics, damp and difficult-to-bond woods. This boat repair epoxy is strong enough to bond different materials and flexible enough to absorb the stress of expansion, contraction, shock and vibration. Ideal for aluminum boat repair, polyethylene or ABS kayak and canoe repair, general structural bonds, and to wet out fiberglass.

Liquid G/Flex 650 is a two-part (resin and hardener) with a 1:1 mix ratio. Choose from 4 different sizes of West System epoxy adhesive: 8 oz. kit, 32 oz. kit, 2 gallon kit, 4.75 gallon resin only, and 4.75 gallon hardener only.

Easy to use

Used G-Flex to glue together large pieces of a teak helm seat with dowels. Thicker than regular West System epoxy but plenty of work time. Use acetone to clean wood before gluing. Dries clear. Dried excess sanded off without much problem. Glue lines between pieces are barely discernible and only on close inspection.

Q: null I want to make bent and laminated handles for some copper utensils; I made a 2 part form, applied G/flex epoxy between the layers of wood to be laminated, and clamped it up. I know that there is some springback to be expected, but will this adhesive allow the layers to continue to ""creep"" and so wind up with a straight handle?

A: I'm not sure G flex is the right product. For starters it is not considered food safe. Also epoxy starts to soften around 125 degrees. You might want to reach out direct to West System at 866-937-8797

Q: null I am looking at purchasing the g-flex 2 gallon kit. My question is about the pumps. I don't understand the group sizing and the mini pump sizing and how they correlate. But I'd like to have the mini pump threaded directly to the gallon containers to dispense the correct 1:1 ratio in an efficient and clean manner. Can you help me figure out what mini pump I need for the gallon sized can? Thank you.

A: Hey Nick, Thank you for reaching out. It is not recommended to use pumps with gflex due to the viscosity. You could attempt it, by getting 2 pump kits and using the resin pump from the kits in each container, but being thicker you likely will not have a good experience.

Q: null can G flex be used to repair vacuum formed thermo plastic. I am working on a Johnson outboard motor hood 2001 vintage 150 HP.

A: It should work on plastic, here is what West System instructs: Plastics Sand ABS, PVC and polycarbonate plastics with 80-grit sandpaper to provide texture for improved adhesion. Some plastics like HDPE and LDPE (high-density and low-density polyethylene) benefit from flame treating. First wipe the bonding surface with a solvent to remove contamination and dry with a clean paper towel. FLAME TREATING—Pass the flame of a propane torch across the surface quickly. Allow the flame to touch the surface, but keep it moving—about 30 to 40 cm per second. No obvious change takes place, but the flame oxidizes the surface and dramatically improves adhesion with adhesives and coatings applied over it. While flame treating will improve adhesion to most plastics, it appears to provide the greatest benefit to polyethylene. If you are unsure of the type of plastic, it doesn’t hurt to flame treat.

Q: null The aluminum rails of my truck cap were originally adhered to the fiberglass shell of the cap, they have begun to separate, would this be a good product to reattach the two? What kind of prep would be needed on each surface for a good bond?

A: Yes that will work well. Be sure to sand and clean the aluminum just before you apply the epoxy to prevent oxidation from interferng with the bond.
