REXBOND ADHESIVE

Rexline Engineering is one of the largest Adhesives and Chemical manufacturer  globally. We are able to offer clients a full range of Chemicals from primers to  adhesives.

Our RexBond Rubber Cement has been specially formulated and engineered to offer  secure bonding to any substrate. RexBond Rubber Cement is becoming a fast  growing industry name due its long tack time which makes for easy application for  rubber lining applicators.

REXBOND Rubber Cement

  • REXBOND Rubber Cement is a 2 Part Component Adhesive with REX-HARDENER re-  curing agent.
  • REXBOND RC offers a high initial grab, heat resistance and good open time.
  • REXBOND RC has been specially formulated and engineered to bond rubber to  rubber and rubber to metal in mining applications.

TECHNICAL DATA SPECIFICATIONS

COLD BONDING ADHESIVE

DESCRIPTION

RexBond Rubber Cement is a 2 – component  adhesive (together with REX-HARDNER RE-  CURING AGENT) developed for use in rubber  bonding applications. It offers HIGH INITIAL GRAB,  HEAT RESISTANCE, and GOOD OPEN TIME.

FIELDS OF APPLICATION

Bonding rubber to rubber and rubber to metal in

mining applications.

SURFACE PREPARATION

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

Metal: Sandblast surface to remove any rust then  clean with ADHESIVES 101 CONTACT CLEANER.

Prime metal surface using REXBOND 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.

APPLICATION

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  REX-HARDENER RE Curing Agent into required  quantity of Rubber Cement. Use within 2 – 3 hours.  Apply 2 coats of adhesive to bonding surfaces with  a brush, allowing ~ 1 hour between coats.

Coverage Rate: ~ 4 m²/Litre per coat. 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.

Full cure occurs after ~ 7 days but may take  longer due to substrates causing solvent  entrapment

CLEAN UP

Clean brushes and rollers in ADHESIVES 101  CONTACT CLEANER.

TECHNICAL DATA

Base   –   Polychloroprene Rubber

SAFETY DIRECTIONS

Avoid contact with skin and eyes and avoid  breathing the vapour or spray mist. Store under  cover, out of direct sunlight and in a well-  ventilated area. Keep away from all sources of  ignition – No Smoking.

FIRST AID

If poisoning occurs, contact a doctor or Poisons  Information Centre. If swallowed, DO NOT induce  vomiting. Give a glass of water. If in eyes, hold  eyes open, flood with water for at least 15  minutes and see a doctor. Refer to Safety Data  Sheet for further information.
