Step 4: The Purging process can be done by purging or injection. **

Step 5: Maintain continuous purging until resin appears natural and clean.

Step 6: The Purging process is complete, resume with standard procedures for next job.

* With applications that require more than one PurgeMax® (refer PurgeMax® Usage Chart) , place one PurgeMax into the hopper and follow with a small amount of purging resin (layering) and repeat until entire dosage has been added then charge the barrel with purging resin.
