The Problem-Solution Series: Part 3
What To Do When Parts are Being Picky: Little or No Adhesion
Problem:
For some reason, little or none of the coating seems to be
adhering to the part. What should I do to fix this.
Origin/ Cause:
In most cases, coating will fail to adhere due to excess
soils.
Solution:
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.
