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.
Araldite® 2085 A/B structural adhesive is available in cartridges which can be fitted with a disposable mixing nozzle and can be applied as ready to use adhesive with the aid of the tool recommended by Huntsman Advanced Materials.
Application of adhesive
The mixed resin / hardener may be applied manually or using some automated application equipment 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. It should also be emphasized that the design of the assembly is also critical for a durable bond. The joint components should be assembled and clamped in the desired position as soon as the adhesive has been applied. For more detailed explanations regarding surface preparation and pretreatment, adhesive joint design, and the dual cartridge dispensing system.
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 acetone are used for cleaning, operators should take and wear the required personal protective equipment to prevent any contact with skin and eyes.

- Processing Guidelines
Processing Recommendations
The temperature where gelation is being carried out should not be higher than necessary. A high gelation temperature induces shrinkage and generates internal stress within the part.

- 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 noted otherwise, 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.
- The joint area was 0.5 x 1 in (12.5 x 25 mm) in each case.
