Material Notes:

PERMABOND ET538 is a structural, room temperature curing epoxy adhesive that has excellent adhesion to a wide variety of surfaces such as wood, metal, ceramics and many plastic and composite materials. It exhibits good resistance to petrol, oils and water and has an extended cure time making it suitable for larger applications and batch production processes. Its thixotropic "non-slump" nature makes it suitable for gap filling or vertical application. Features & Benefits: Adhesion to a wide variety of substrates Full cure at room temperature Easy to apply High shear and peel strength Good impact strength Good chemical resistance Non-drip rheology Information provided by Permabond.
