Getting Your Aircraft Coatings to Actually Cure

When you’re dealing with anti-icing or anti-corrosion coatings on a plane, you can’t just “wing it.” These coatings need a very specific heat profile to bond properly. If one spot on the wing is a few degrees cooler than the rest, you’re looking at uneven curing. And in the real world? That means the coating peels off the moment it hits extreme flight conditions. Not great. To fix this, we use short-wave infrared (IR) heaters. Why IR beats the oven Most people think of big convection ovens. But those just heat the air, and the air eventually heats the part. It’s slow. Plus, aircraft shapes are weird—all those curves and angles make it a nightmare to get a steady temp. Short-wave IR is different. It ignores the air and hits the coating directly. It’s like a heat lamp for a plate of food, but way more powerful. By cranking up the energy density, the chemical reaction happens everywhere at once. If it’s too hot or not hot enough, you just move the lamps or tweak the power. Simple. The gear we use We usually go with quartz halogen elements. Why? Because quartz doesn’t warp when things get scorching. The halogen gas is the secret sauce—it pushes the tungsten back onto the filament, which means the bulbs last a lot longer. The real trick is wiring them into a zoned control system. Since aircraft parts are curved, you naturally get “cold spots.” With zones, you can just blast more heat into those specific areas to keep everything level. The “Gotchas” It’s not all magic, though. There are a few things that can trip you up. First, these arrays pull a ton of power. If you aren’t careful with your electrical panels, the initial surge will pop your breakers the second you flip the switch. Then there’s the “boil” factor. If you hit the surface too hard and too fast, the solvents in the coating start to boil. This leaves tiny pinholes in your anti-corrosion layer, which basically ruins the whole job. That’s why we keep a close eye on the substrate with pyrometers. When you get the calibration right, the guesswork disappears. You get a rock-solid cure, the thickness stays consistent, and you can get the part into flight testing way faster.
