The strength and durability of a bonded joint are dependent on proper pretreatment of the surfaces to be bonded. At the very least, joint surfaces should be cleaned with a good degreasing agent such as acetone or trichloroethylene, in order to remove all traces of oil, grease and dirt. Never use alcohol, gasoline or paint thinners. The strongest and most durable joints are obtained by either mechanically abrading or chemically etching (“pickling”) the degreased surfaces. Abrading should be followed by a second degreasing treatment.- Application Information

Technical Details & Test Data
- Typical Cured Information
Unless a different specification is given, the figures below were all determined by testing standard specimens made up by lap-jointing 4-in x 1-in x 0.06-in (10-cm x 2.5-cm x 1.5-mm) strips of aluminum.The joint area was 0.5 inch x 1 inch (12.5 mm x 2.5 cm) in each case. Samples were cured 7 d at 77°F (25°C) and values measured at 25°C.

Storage & Handling
- Storage Conditions
Araldite® 1258 A/B Adhesive should be stored in a dry place, in the original sealed containers,at temperatures between 2°C and 40°C (36°F and 104°F). Under these storage conditions, the products have a shelf life of 3 years (from date of manufacture).The products should not be exposed to direct sunlight.If stored below 60°F, the adhesive should be brought to 60°F - 77°F and conditioned at this temperature for some time prior to use.
