Typical times to minimum shear strength on sandblasted aluminum / contact pressure

Pretreatment

The strength and durability of a bonded joint are dependent on proper pretreatment of the surfaces to be bonded, however the methacrylate adhesives can be used effectively with little surface preparation. Ideally joint surfaces should be cleaned with a good degreasing agent such as acetone, iso-propanol (for plastics) or other proprietary degreasing agents in order to remove all traces of oil, grease and dirt. Low grade alcohol, gasoline (petrol) or paint thinners should never be used. The strongest and most durable joints are obtained by either mechanically abrading or chemically etching (“pickling”) the degreased surfaces.

Application of adhesive

This system is available in cartridges incorporating mixers and can be applied as ready to use adhesive with the aid of the tool recommended by Huntsman Advanced Materials. The resin/hardener mix may be applied manually or robotically to the pretreated and dry joint surfaces. Huntsman's technical support group can assist the user in the selection of a suitable application method as well as suggest a variety of reputable companies that manufacture and service adhesive dispensing equipment. A layer of adhesive 0.25 mm thick will normally impart the greatest lap shear strength to the joint. The joint components should be assembled and secured in a fixed position as soon as the adhesive has been applied.

Temperature of application: The recommended temperature application range is 50°F to 104°F.

Warning: The cure reaction can generate a high amount of heat, it is not recommended to mix large amounts of material at room temperature.

Equipment maintenance

All tools should be cleaned with hot water and soap before adhesives residues have had time to cure. The removal of cured residues is a difficult and time-consuming operation. If solvents such as MEK are used for cleaning, operatives should take the appropriate precautions and, in addition, avoid skin and eye contact.

Unless otherwise stated, the figures given below were all determined by testing standard specimens made by lap-jointing 114 x 25 x 1.6 mm strips of aluminum alloy. The joint area was 12.5 x 25 mm in each case. The figures were determined with typical production batches using standard testing methods. They are provided solely as technical information and do not constitute a product specification.

Average lap shear strengths of typical metal-to-metal joints (ISO 4587) (typical average values)

Cured for 7 days at RT and tested at 73oF. Substrates sandblasted and degreased with acetone. They are typical values only, and do not constitute a product specification.

Note: ARALDITE® 2053-15 is not suitable for galvanized steel, for this type of substrate the ARALDITE® 2047-1 or ARALDITE® 2051 can be used.

Huntsman Advanced Materials Americas LLC maintains up–to-date Safety Data Sheets (SDS) on all of its products. These sheets contain pertinent information that you may need to protect your employees and customers against any known health or safety hazards associated with our products. Users should review the latest MSDS to determine possible health hazards and appropriate precautions to implement prior to using this material.

ARALDITE® 2053-15 Structural Adhesive may be stored for 24 months between 36°F and 46°F (2.2°C and 7.8°C) provided the components are stored in the original sealed containers. The expiry date is indicated on the packaging. The product should be allowed to equilibrate at room temperature before use, but the total time at room temperature should not exceed 9 months. Long term exposure above 77°F will reduce the shelf life of the product.
