How To Choose Non Stick Coatings For Industry
Your equipment has just gone into service and yet it's not working? How come? After all, it was built to print and that included a non stick coating. If you believe all industrial non stick coatings are created equal, I have some bad news for you. But don't be overwhelmed. You need to just start with these simple truths: No two industrial non stick coatings work exactly alike in the same environment and none of the industrial non stick coatings works exactly alike in two different environments. It's not always the fault of the industrial non stick coatings, you see. Often, it's failure to understand the environment it will have to withstand. So you probably already know what can result. So, what makes good non stick industrial non stick coatings? First of all, sticking occurs when molecules of a substance have stronger attraction to a surface than to each other.
Conversely, if molecules have greater attraction for each other than the surface, non stick occurs. Make sure not to confuse sticking with lubrication. The two phenomena are very different. We say the more difficult it is to 'wet' a surface, the better the non stick. Imagine a freshly waxed car and how easily water is repelled. Generally, the more hydrophobic, or water-repelling industrial non stick coatings are, the better the release. Manufacturers of PTFE, PFA, MFA, or FEP are all excellent non stick polymer-agents. To pick a non stick coating right for you, look for hydrophobic characteristics. But never forget the environment! Heat, chemical, and mechanical factors simply can't be ignored. Today, advancements in non stick technology continue both for release and for wear. New fillers or binders, for instance, can offer exceptional forms of 'internal' reinforcement. Hardening or other 'external' reinforcements, including anodizing, plating, vapor deposition, and thermal spray, by some providers, has produced fabulous results for industrial non stick coatings.
