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.
