APPLICATION
PRECISION
Teflon™ application requires precise thermal cycles. We utilize multi-coat systems starting with high-adhesion primers, followed by topcoats of PTFE, FEP, or PFA depending on the service environment. The final sintering occurs at strictly monitored temperatures to ensure a uniform, low-friction industrial finish.
TEFLON™ FAQ
Common questions regarding industrial Teflon™ (PTFE, PFA, FEP) coating applications, metallurgical constraints, and wear factors.
Why is PFA preferred over PTFE for highly corrosive chemical immersion linings?
PTFE is a micro-porous fluoropolymer formed by sintering compacted powder. While it has excellent thermal resistance, corrosive liquids and gases can permeate the micro-voids over time. PFA (Perfluoroalkoxy) is melt-processible and flows during cure to form a completely solid, non-porous barrier with significantly lower permeation rates.
What substrate metal limitations exist for high-temperature Teflon curing cycles?
Teflon coatings require sintering temperatures between 380°C and 400°C (715°F to 750°F). High-carbon steels may undergo changes in metallurgical properties (tempering/softening) at these temperatures. Low-melting point alloys like aluminum are limited to specialized formulations (such as FEP or one-coat systems) that cure below 315°C.
How do you verify and document the adhesion strength of the sintered Teflon coating?
We test and verify paint/coating adhesion by performing a cross-hatch tape test in accordance with ASTM D3359 Method B for coatings under 125 microns. For thicker industrial layers, we perform destructive peel tests on witness coupons processed under identical thermal parameters.
Is industrial Teflon coating completely scratch-resistant?
No. Pure PTFE and PFA are soft polymers with low shore hardness (around 50 to 60 Shore D). For sliding wear or abrasive environments, we formulate the system with reinforcing ceramic or metallic binders (like stainless steel particles) to improve wear resistance without losing the non-stick release properties.
Can Teflon be applied over food-contact equipment without regulatory risks?
Yes. We use specific FDA-compliant formulations that meet the strict requirements of 21 CFR 177.1550. These coatings are chemically inert, non-toxic, and safe for continuous direct contact with food products at temperatures up to 260°C.
