Araldite AY 103-1 resin

Medium viscosity epoxy adhesives

Araldite AY 103 resin is two-part, medium-viscosity adhesives that are ideal for bonding metals, ceramics, glass, rubber and plastics. The solvent-free epoxy adhesives produce chemical-resistant, electrically insulating joints with good mechanical strength. Araldite AY 103 resin can mix with Hardener HY 951 or HY 956

The resin/hardener mix may be applied manually or robotically to the pretreated and dry joint surfaces. Creative Engineering‘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 0.002 to 0.004 inch (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.
