Permabond ET00538K050S0101

ET538 Toughened Thixotropic Two-Part Epoxy, Cream/Black, 50ml Cartridge

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.

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
