Specialty Epoxies

WEST SYSTEM Specialty Epoxies are cure-compatible with each other, and also with the 105 System. If you wish to blend one with another, first mix on ratio the resin and hardener from one of our specialty epoxies, then add it to mixed on-ratio resin and hardener from another. For example, to speed the cure of 105/205 you may mix a batch of this at the correct (5:1 – one pump each with our calibrated mini pumps) then blend with mixed 1:1 ratio G/5 Five-Minute Adhesive or G/flex Epoxy.

G/flex Epoxy

G/flex Specialty Epoxies are easy-to-use, toughened, resilient, two-part specialty epoxies designed to make structural bonds that absorb the stresses of extraordinary expansion, contraction, shock, and vibration. These epoxies have excellent adhesive properties and are engineered to grip tenaciously to metals, plastics, glass, masonry, fiberglass, and wet and difficult to bond woods. Easy-to-use 1:1 mix ratio gives you 46 minutes of pot life and a long open time (or working) time of 75 minutes at 72°F. Reaches an initial cure in 3-4 hours and a workable cure in 7-10 hours. G/flex Specialty Epoxies are available in two consistencies:
