Loctite AA H3151 Light Yellow Acrylic Adhesive in 55 Gallon Drums - Part A & B

Loctite AA H3151 Light Yellow Acrylic Adhesive in 55 Gallon Drums Overview

Loctite AA H3151 is a medium-viscosity, two-component methacrylate adhesive system engineered for strong, durable metal-to-metal bonds. Packaged as separate Part A (Resin) and Part B (Hardener) in bulk 55-gallon drums, it features a 1:1 mix ratio and an extended open time of 45–60 minutes, allowing for precise part positioning during assembly. This non-sagging adhesive fills gaps up to 0.5", requires little to no surface preparation, and bonds automotive-grade cold-rolled steel, aluminum, and other metals without primer. Glass beads provide consistent bondline thickness, while excellent environmental resistance ensures long-term durability in industrial applications.
