Permabond® ET5147 – Engineering Adhesive (2-Part Epoxy)

Key Features (why engineers choose this)

2:1 mix epoxy system → controlled curing process
High strength bonding (up to ~2900 psi shear strength)
Excellent resistance to impact & vibration
Thixotropic (non-sag gel) → stays in place even on vertical surfaces
Room temperature curing (no oven required)
Food-grade compliant (FDA CFR 175.105 / 175.300)

Benefits

Adhesion to a wide variety of substrates
Full cure at room temperature
FDA Compliant formulation
High shear and peel strength
Good impact strength

PERMABOND® ET5147 is a 2:1 mixable epoxy adhesive. It has excellent resistance to impact and vibration and is ideal for structural bonding of metal, wood, composites and certain plastics. Its rapid cure speed coupled with its structural strength makes this adhesive suitable for a wide variety of applications. ET5147 is high strength and has excellent environmental durability.
