Demystifying Outgassing: Understanding the Process and Application in Powder Coating | Joey Golliver

Introduction: Join Joey Golliver, the world-renowned powder coating expert and author of “The Powder Coach’s Playbook,” as he delves into the process of outgassing and its application in powder coating in this enlightening video. Proper outgassing is crucial for achieving flawless coatings and preventing common surface defects.

Understanding Outgassing: In this comprehensive discussion, Joey explains what outgassing is and how it occurs during the powder coating process. Key points include:

  • What is Outgassing? Outgassing is the release of trapped gases from within a substrate as it is heated during the curing process. These gases can create bubbles, pinholes, or other surface defects if not properly managed.
  • Why is Outgassing Important? Proper outgassing is essential for preventing defects that can compromise the adhesion, appearance, and durability of the powder coating. Understanding and controlling this process ensures higher quality finishes.

Common Causes of Outgassing: Joey identifies common causes of outgassing, including:

  • Porous Substrates: Materials like cast metals or certain plastics that have inherent porosity can trap air and other gases.
  • Freshly Machined Parts: Machining processes can introduce oils and contaminants into the surface that need to be removed before coating.
  • Contaminants: Oils, grease, and other surface contaminants that haven’t been adequately cleaned can cause outgassing during curing.

Effective Outgassing Techniques: Joey shares practical tips and industry-proven techniques to manage outgassing effectively:

  • Pre-Baking: Pre-baking the parts at a temperature slightly higher than the curing temperature can help release trapped gases before the powder is applied.
  • Proper Cleaning: Ensure all surfaces are thoroughly cleaned and degreased to remove contaminants that could cause outgassing.
  • Using Outgassing-Primer Coatings: Special primers designed to handle outgassing can be applied to create a barrier and prevent gases from affecting the topcoat.

When to Apply Outgassing Techniques: Joey provides guidance on when and how to apply outgassing techniques based on specific situations:

  • Porous or Cast Materials: Always pre-bake these materials to reduce the risk of outgassing.
  • Intricate Designs: Pay extra attention to parts with complex shapes or areas prone to trapping contaminants.
  • High-Performance Applications: For coatings that require the highest quality and durability, rigorous outgassing procedures are essential.
