Formulating a non-stick coating from initial concept to production - pdf

The formulation of new coatings is often done by looking at existing formulations, then modifying them to meet the customers requirements. This presentation looks at a high performance solvent based polyamide-imide resin system that had high temperature properties, then reformulating it to both improve its flexibility and change the solvent system to water based for use as a binder system for a low friction coating. The presentation goes through the changes made to the base polymer to provide the improved properties, as well as the changes required to produce a water based system.
As part of the customer approval process, the internal testing required is examined, as well as some of the test methods. Since the customer was just going to purchase the base resin system, and blend the filler in themselves, results are shown of the customer trials with different filler systems. Finally some of the issues encountered during scale up from laboratory to production are discussed.
