Araldite 2012 is a low shrinkage, fast-curing structural adhesive that has been designed to bond an extensive selection of ceramics, metals, rigid plastics, glass, rubbers, and much more. This adhesive is a great general purpose paste that proves itself tough and resilient when bonding a wide variety of materials. From industrial to craftsman’s applications, Araldite 2012 can bond almost any material found in every-day use and is versatile enough to get most jobs done right.
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.
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.
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.
