ARALDITE® 2011 A/B

• Multi-purpose
• Long working life
• Low shrinkage
• Good resistance to dynamic loading
• Bonds a wide variety of materials in common use

Application of adhesive

• 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 0.002 to 0.004 in (0.05 to 0.10 mm) thick will normally impart the greatest lap shear strength to the joint.
• Huntsman stresses that proper adhesive joint design is also critical for a durable bond.
• The joint components should be assembled and secured in a fixed position as soon as the adhesive has been applied.

Pretreatment

• The strength and durability of a bonded joint are dependent on proper treatment of the surfaces to be bonded.
• At the very least, 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, 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.
• Abrading should be followed by a second degreasing treatment.

• 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 acetone are used for cleaning, operatives should take the appropriate precautions and, in addition, avoid skin and eye contact.

Typical Physical Properties

Unless otherwise stated, the data were determined with typical production batches using standard test methods. They are typical values only, and do not constitute a product specification.

Unless a different specification is given, the figures below were all determined by testing standard specimens made by lap-jointing 4.5 x 1 x 0.063 in (114 x 25 x 1.6 mm) strips of aluminum alloy. The joint area was 0.5 x 1 in (12.5 x 25 mm) in each case. Samples were cured at 104°F (40°C) for 16 hours and tested at 23°C, unless otherwise noted.

* - 40/92, DIN 50015; typical average values; test at 23°C

** - Cure 16 h at 104°F (40°C) or 20 min at 212°F (100°C); Test: 4 days in a conditioning chamber in 40/92 climate as specified by DIN 50015; Rating according to specified standard.

*** - Cure 20 min / 212°F (100°C); Mean static lap shear strength: 2364 psi (16.3 MPa); Test carried out using a load cycle frequency of 90 Hz.
