G/flex® 650 is a toughened, highly versatile epoxy adhesive designed for permanent, waterproof bonding across a wide range of materials. With a 1:1 mix ratio for simple, reliable use, this slightly flexible epoxy is engineered to withstand the stresses of expansion, contraction, shock and vibration — making it ideal for structural bonds where movement or impact resistance is required.
Viscous enough to stay in place without draining from joints, G/flex® 650 adheres exceptionally well to plastics, metals, aluminium, fibreglass, glass, ceramics, masonry, damp wood, difficult-to-bond wood species, and dissimilar materials. It is widely used for repairing aluminium boats, bonding polyethylene and ABS kayaks and canoes, timber repairs, and a range of marine, household and sporting equipment.
G/flex® 650 can also be modified with WEST SYSTEM® fillers and additives, and used to wet out fibreglass tapes and fabrics for reinforced repairs.
– Toughened Performance for Demanding Bonds.

Six10™ Thickened Epoxy Adhesive delivers the strength, reliability and proven performance of a two-part WEST SYSTEM® epoxy in an easy-to-use, point-and-shoot format. Packaged in a self-metering coaxial cartridge, Six10™ dispenses a pre-thickened, gap-filling structural adhesive that cures to a tough, waterproof bond. The included static mixer blends the resin and hardener automatically, allowing users to apply a precise bead of epoxy using any standard caulking gun.
Formulated for versatility, Six10™ bonds tenaciously to wood, fibreglass, metals, composites, masonry and concrete, making it ideal for structural gap-filling, hardware installation, repairs and general bonding applications.
– Structural Strength. Cartridge Convenience.

 |
PFC | Perforated | 3 mm perforations in diamond pattern with 100/50 mm spacing. | Secures core bonding to laminate in bagging operations with core-bonding adhesive or wet bagging. | For infusion, PF20 is recommended to ensure good wet-out. |
 |
PF20 | Perforated | 2 mm perforations in square pattern with 20 mm spacing. | Ensures proper core bonding in vacuum-assisted processes such as infusion. | Most common perforation option for prepreg or infusion. |
 |
GRC4 | Grooved | 2×2 mm grooves in width and/or length direction, c/c 20 mm, on one or two sides. | Fast, reliable resin distribution in vacuum-assisted processes. | Best for larger panels and core thickness above 20 mm. Not recommended where very high surface finish is required. |
 |
GRC6 | Grooved | 2×2 mm grooves c/c 20 mm along the sheet on two sides. | Fast, reliable resin distribution in vacuum-assisted processes. | Suited to large areas and thicker cores; avoid where ultra-high surface finish is needed. |
 |
GRC8 | Grooved | 2×2 mm grooves c/c 20 mm across the sheet on two sides. | Fast, reliable resin distribution in vacuum-assisted processes. | Ideal for large panels and core thickness above 20 mm; not for very high finish surfaces. |
 |
GPC1 | Grooved & Perforated | 2×2 mm grooves c/c 20 mm in both directions on one side with 2 mm perforations in the grooves. | Very fast, reliable resin distribution in vacuum-assisted processes. | Perforations transfer resin & wet out mould-side laminate. Reduced print-through thanks to small perforations. |
 |
GPC2 | Grooved & Perforated | 2×2 mm grooves c/c 20 mm in both directions on both sides with 2 mm perforations in the grooves. | Very fast, reliable resin distribution in vacuum-assisted processes. | Perforations transfer resin to both skins. Not recommended where very high surface finish is required. |
 |
GPC8 | Grooved & Perforated | 2×2 mm grooves c/c 20 mm along the sheet on two sides with 2 mm perforations in the grooves. | Fast, reliable resin distribution in vacuum-assisted processes. | Perforations transfer resin & wet out mould-side laminate; not for ultra-high surface finish. |

 |
Q103 | Cuts, Grooves & Perforations | GW30 scrim-backed grid scoring with 2×2 mm GPC1 grooves and 2 mm perforations in the grooves. | Very fast, reliable resin distribution & laminate wet-out in curved-area infusion. | Wider cuts used where density or thickness requires it. |
 |
Q300 | Cuts & Perforations | GS30 scrim-backed grid scoring with 2 mm PF20 perforations. | Fast, reliable resin distribution in vacuum-assisted processes for curved areas. | Reduced print-through due to small perforations on mould side. |
