LOCTITE EA 9461 LOCTITE® EA 9461 is a 2-part, grey structural-bonding epoxy resin. It cures at room temperature to provide a toughened bond, so it’s ideal for joining dissimilar substrate materials including metals, motoring thermoplastics, and thermoset laminates such as SMC. Its thixotropic properties make it great for gap-filling, and you can expect high peel and shear strength.
