Specbond 32 – Cold Bonding Adhesive

Specbond 32, when combined with SPEC33 Curing Agent, forms a two-component adhesive developed specifically for rubber bonding applications. It provides strong initial adhesion, exceptional heat resistance, and an ample open time for versatile use.

  • Bonding rubber to rubber and rubber to metal in mining applications.

Surfaces to be bonded should be clean and free from oil, dust, loose and other foreign materials.

Metal:
– sandblast surface to remove any rust then clean with TAC ADHESIVES – 101 CONTACT CLEANER
– Prime metal surface using Chemlok 205 Metal Primer allowing primer coat to completely dry before applying adhesive coat

Rubber:
– Buff then clean the rubber surface with a quick drying petroleum based solvent.
– Natural Rubber surfaces may need Chlorination for maximum adhesion

Best results are obtained under the following conditions:

– Workshop, material and glue temperature: 20°C
– Relative humidity: 60 – 70%

  • Thoroughly mix approximately 4 – 7% by weight of SPEC33 Curing Agent into required quantity of Specbond 32 adhesive.
  • Apply 2 coats of adhesive to bonding surfaces with a brush, allowing ~ 1 hour between coats.
  • After the second coat allow adhesive to evaporate until it is no longer tacky to touch.
  • Join surfaces before end of open time.
  • Apply as much pressure as possible to obtain optimum bond strength.
  • Use within 2-3 hours.

  • Recoat time @20°C: 1 hour
  • Full Cure: 7 days, but may take longer due to substrates causing solvent entrapment.

Use TAC 101 CONTACT CLEANER

  • Store under cover, out of direct sunlight and in a well ventilated area.
  • Keep away from all sources of ignition.
  • Shelf life is 12 months when stored as per above recommendations.
