Product Description
LOCTITE® ABLESTIK GA 47-2LV is a green, low-viscosity, heat-cured epoxy instrument adhesive. It is documented as compatible with conventional gyro flotation fluids and has a coefficient of thermal expansion that approximates aluminum within a normal temperature range. The material provides a typical viscosity of 50,000 mPa·s, a 30-minute work life at 25°C, and guideline cure options of 2 hours at 95°C or 4 hours at 75°C. Cured aluminum-to-aluminum lap shear strength is reported as 13.8 N/mm². :contentReference[oaicite:0]{index=0}
