Araldite 2012 Adhesive is a high viscosity liquid that is made up of two components and cures at room temperature. 2012/A is opaque in color, 2012/B is pale yellow, and when mixed together the combination should be pale yellow. This material’s specific gravity (mixed) is ca 1.18, and its viscosity at 77°F is typically 25,000- 35,000 cP. Araldite 2012 Adhesive’s pot life for 100 gm at 77°F is 5-8 minutes, and the shelf life for each component when kept separate is 3 years. For more technical information regarding this product, please see the Araldite 2012 Technical Data Sheet.
Before utilizing any Araldite 2012 Epoxy Paste Adhesive, it is important to properly pretreat the surfaces that are to be bonded, as the durability and strength of the bond depend on it. A quality degreasing agent should be used at the very least in order to remove any traces of dirt, oil, or grease. Acetone or other proprietary degreasing agents can be used to do this, but never gasoline, paint thinners, or low-grade alcohol. The sturdiest and most long-lasting joints attained when using Araldite Epoxy Paste Adhesive are those which have surfaces that are either chemically etched or mechanically abraded before bonding. After mechanically abrading a surface to prepare it for a strong bond, an additional degreasing treatment should follow before using the adhesive.

Once the surfaces that are to be bonded are pretreated, cleaned, and dried, Araldite 2012 mix can be applied either robotically or manually. Maximum lap shear strength can be attained by applying a layer of adhesive between 0.002 – 0.004 inches thick. For the best bond, the joint components should be brought together and held in a secure position the moment Araldite 2012 has been applied. After the adhesive has been placed onto the components, and the surfaces have been secured together, any tools used in the process should be washed with soap and hot water before the adhesive residue has a chance to cure. Removing cured residue left behind on tools is a slow and challenging process.
Araldite 2012 Epoxy Paste Adhesive is a great option for a wide range of general purpose bonding applications. From personal to professional use, this two-part paste cures quickly and performs efficiently. The use of appropriate personal protective equipment is recommended in order to avoid any possible health risks presented by this product.
