BOND 1308 / HARDENER 95A6

BOND 1308 / HARDENER 95A6 is a tough, two-component system that is well suited for a broad range of filter bonding applications. The high-strength epoxy adhesive features good stability in the presence of heat as well as flexural and compressive stresses. Bond 1308 resin/hardener systems bond well to metals and plastics. In addition to performing as adhesives, the products are suitable for use in potting and encapsulating applications.

Processing Information

Pretreatment:

  • The strength and durability of a bonded joint is dependant on proper pretreatment of the surfaces to be bonded.

  • At the very least, joint surfaces should be cleaned with a good degreasing agent such as acetone 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.

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.

 

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 or MEK are used for cleaning, operators should take the appropriate precautions and, in addition, avoid skin and eye
Typical Cured Properties

Unless otherwise stated, the figures given 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. 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.

Storage & Handling

Storage Conditions
  • BOND 1308 / HARDENER 95A6 is a structural adhesive that should be stored in a dry place, in the sealed original container.
  • BOND 1308 should not be exposed to direct sunlight. It should be stored at temperatures between +2°C to +40°C.
  • Under these storage conditions, the shelf life is 3 years.
  • HARDENER 95A6 should be stored at temperatures between +2°C to +40°C.
  • Under these storage conditions, the shelf life is 1 year. If stored below 60°F, the adhesive should be brought to 60°F – 77°F and conditioned at this temperature for some time prior to use.
