LA7337BLK

LA7337BLK is a two-component, room-temperature adhesive system specifically designed for installing cured or uncured rubber materials to themselves or onto primed steel surfaces. When used with our PC4426BKMOD, it creates strong bonds to various rubber compounds and metals. Typical applications include abrasive slurry pipe linings, conveyor belts, impact-resistant bonding, tank liners, and many other applications.

General Instructions
  • For optimal bond strength performance, buff cured rubber and then solvent clean with Toluene or MEK.
  • When bonding to metal, follow the instructions on the HB Fuller PC4426BKMOD technical data sheet.
  • Before use, pre-stir the LA7337BLK adhesive and mix it thoroughly with the CAT7337 catalyst.
  • The mix ratio is 5.5 parts catalyst/100 parts LA7337BLK by weight or 6.0 fluid oz per gallon.
  • After the final coat has dried, use a cloth dampened with Toluene and wipe over both surfaces to be bonded.
  • Once an aggressive tack is achieved, mate the two surfaces and roll out with a 2# metal roller to ensure proper adhesion.
  • Depending on the temperature and humidity, the parts can typically be handled in 24 hours.
  • Full bond strength cure is achieved in seven days.
  • The pot life of the catalyzed adhesive is 4 hours.
