LOCTITE® EA 9450 is a fast-curing adhesive with an epoxy resin and mercaptan hardener designed for mixing in structural bonding applications, providing high-strength hold and non-sagging properties. This ultra-clear adhesive is recommended for the bonding and repair of components, providing excellent gap fill and vertical performance.
LOCTITE® EA 9450 is a specially formulated structural bonding adhesive featuring a medium viscosity, 2-part formulation with a 1:1 mix ratio by volume, allowing easy mixing and application. It cures quickly at room temperature upon mixing the resin and hardener, providing an excellent adhesive paste that adheres to metals, plastic, ceramics, and glass with an ultra-clear bond line. Its exceptional non-sag properties ensure optimal vertical performance, efficiently filling gaps and bonding components without run-off. LOCTITE® EA 9450 provides excellent fixture after 13 minutes and reaches full cure after 3 to 6 hours.
