G/flex® 650 Toughened Epoxy Kit – 250ml (2 x 125ml Bottles)

G/flex® 650 is a toughened, flexible two-part epoxy resin system developed by WEST SYSTEM and manufactured in Australia by ATL Composites. This 250ml kit includes two 125ml bottles (resin and hardener) and is ideal for knife makers, woodworkers, and metalworkers needing high-strength bonds with added flexibility.

Designed to bond dissimilar materials — including wood, metal, plastic, composites, and damp or oily surfaces — G/flex 650 absorbs shock, vibration, expansion, and contraction. Its slightly flexible cured state (modulus of elasticity 1075 MPa) makes it perfect for handle bonding in knives and tools.

**Key Features:**
- 250ml kit (2 x 125ml bottles: resin + hardener)
- 1:1 mix ratio by volume
- Pot life: 40 minutes @ 25°C
- Cures in 12 hours (thin laminate @ 25°C)
- Shore D Hardness: 75 after 24 hrs
- Minimum working temperature: 10°C
- Mix viscosity: ~11,200 mPas @ 25°C
- Bonds wood, metal, plastics, composites, and more
- Waterproof and sandable after cure
- Made in Australia

G/flex 650 can also be thickened with WEST SYSTEM fillers for gap filling, or used as-is for wetting out fibreglass reinforcements. It's a reliable choice for makers who need strong, flexible performance where other adhesives might crack under stress.
