Araldite epoxy resin adhesives form extremely strong durable bonds with metals, glass, rigid plastics, rubber and many other materials. Designers in every sphere of industry increasingly find that bonding with Araldite provides the answer to production problems posed by new materials, new uses of existing materials and new techniques and manufacturing methods. Araldite resins adhere firmly to most materials. Bonds of great strength are obtained after removal of grease and loose surface deposits, e.g. rust, from the surfaces to be joined, but when maximum strength is required a more thorough mechanical or a chemical pretreatment is recommended.
