Data values are not guaranteed or warranted unless if specifically mentioned. Processing 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.

March 2016 Araldite 2022-1 Page 1 of 5 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 an suitable application method as well as suggest a variety of reputable companies that manufacture and service adhesive dispensing equipments. A layer of adhesive 0.25 to 0.5 mm thick will normally impart the greatest lap shear strength to the joint. For some metals like mild steel or stainless steel, a higher joint thickness may be necessary to reach satisfactory results. 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.

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.
