Getting PTFE Curing Right with Short-Wave IR

If you’ve ever dealt with PTFE coatings, you know the struggle. You need a very specific, very high temperature to get that polymerization just right. But here’s the problem: standard heating usually just hits the surface. You end up with “uncured pockets” or a coating that just peels off because it never actually bonded. That’s why we lean on short-wave infrared (SWIR) lamps. By focusing on that 0.75 to 2.5 $\mu$m wavelength, we can actually get the heat where it needs to be.

Getting a Deep Cure in PTFE Without Burning Everything

Curing PTFE (your standard Teflon) is a bit of a balancing act. You need enough heat to get those polymer chains to bond properly, but if you overdo it, you’ll scorch the substrate before the coating even sets. It’s a frustrating spot to be in. To fix this, we use a mix of custom-spectrum IR lamps and high-reflectivity aluminum plates. The goal is simple: push the heat deep into the coating, not just sizzle the top.
