Applications Araldite®

 AV/HV 1580 GB is an easily worked cold setting two part epoxy resin putty. On curing, the putty provides a

tough durable material which is dimensionally stable and resistant to chemical attack. It also forms strong bonds

with most structural materials (metals, glass, Plastics, wood, dry concrete, rubber, etc.)

Araldite®

 AV/HV 1580 GB putty is employed as a general-purpose gap filling material. Besides modeling and gapjoint

bonding, the uses of the putty include cable-jointing, the repair of cold/hot water pipes and tanks, the infilling,

contouring or balancing of parts subject to high levels of vibration, the encapsulation of small electrical units-and

resin tooling, such as in the construction of frame works for Araldite®

 laminated jigs and fixtures.

Araldite®

 AV/HV 1580 GB putty has co-efficient of expansion similar to the values for copper and steel. This suits the

putty for use in electrical equipment operating down to cryogenic temperatures.

The filled putty can be filed sanded and machined.

Processing Pretreatment

The strength and durability of a bonded joint are dependent 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, or a proprietary

degreasing agent 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.
