Advanced Materials Araldite 2014-1 Structural Adhesives TECHNICAL DATA SHEET Araldite 2014-1 Two component epoxy paste adhesive Key properties Grey paste High temperature and chemical resistance Low shrinkage Very resistant to water and a variety of chemicals Gap filling, non sagging up to 5mm thickness Araldite 2014-1 is a two component, room temperature curing, thixotropic paste adhesive of high strength with good Description environmental and excellent chemical resistance. Used for bonding of metals, electronic components, GRP structures and many other items where a higher than normal temperature or more aggressive environment is to be encountered in service. The low out gassing makes this product suitable for specialist electronic telecommunication and aerospace applications.

Data values are not guaranteed or warranted unless if specifically mentioned. 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, alcohol or other proprietary degreasing agents in order to remove all traces of oil, grease and dirt. 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.

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 equipment. A layer of adhesive 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.

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.
