What To Do When Parts are Being Picky: Little or No Adhesion
For some reason, little or none of the coating seems to be adhering to the part. What should I do to fix this.
In most cases, coating will fail to adhere due to excess soils.
First, check that all soils have been identified. Next, test all of the stages. Determine if the proper choices of chemical and process have been chosen in order to remove all soils. Lastly, orient the parts for the maximum amount of coverage and clean, and adjust the spray pressure for maximum part coverage. Throughout the process, be sure to maintain high rinse tank purity.
