G1 (1:1 ratio) was developed for use on wooden airframes and offers long working time at high temperatures (recommended for use at 20°C/70°F or over; working time is 60 minutes and cure time is 24 hours). It is the system of choice for projects where large areas are to be glued and when maximum fatigue resistance is required (for skis, golf clubs, etc.).
G2 (2:1 ratio) is formulated to work well on oily and acidic woods (do not use below 10°C/50°F; cure time is 48 hours at 10°C/50°F or 24 hours at 20°C/70°F). Ideal where flexibility is required. The joint will yawn rather than fracture.
Made in USA.
The G1 Epoxies are no longer available.
