Processing Pretreatment
The strength and durability of a bonded joint are dependant 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 (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. Abrading should be followed by a second degreasing treatment

Resin and hardener should be blended until they form a homogeneous mix. Resin and hardener are also 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.
Application of adhesive
The resin/hardener mix is applied with a spatula, to the pretreated and dry joint surfaces.A layer of adhesive 0.05 to 0.10 mm thick will normally impart the greatest lap shear strength to the joint.The joint components should be assembled and clamped as soon as the adhesive has been applied. An even contact pressure throughout the joint area will ensure optimum cure.
Mechanical processing
Specialist firms have developed metering, mixing and spreading equipment that enables the bulk processing of adhesive.We will be pleased to advise customers on the choice of equipment for their particular needs.
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, operatives should take the appropriate precautions and, in addition, avoid skin and eye contact.

Typical cured properties
Unless otherwise stated, the figures given below were all determined by testing standard specimens made by lap-jointing 170 x 25 x 1.5 mm strips of aluminium 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.
