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.

Eliminating Dust Contamination in Aviation Coatings via Infrared Curing

Most traditional spray booths are basically giant wind tunnels. They blast massive amounts of air to keep the temperature up, but there’s a catch: all that airflow acts like a vacuum. It sucks up every bit of dust, lint, and gunk floating around and slams it right into your wet paint. In aerospace, that’s a nightmare. One tiny speck of dust isn’t just an eyesore—it can actually cause a structural flaw or make the whole finish fail. We handle this by ditching the forced-air heating and using Short-Wave Infrared (SWIR) instead. Here’s the thing about infrared: it doesn’t bother heating the air. Instead, it sends out radiation that goes straight through the coating to heat the part itself. Since you aren’t blasting hot air everywhere, you stop moving the dust. We call it “static curing.” You stop the air, and the contaminants just stay put. To make this work, we use high-density quartz tubes. These things hit curing temperature in seconds. It creates this great “skin-over” effect where the top layer of paint hardens almost instantly. This locks out any stray particles before they even have a chance to settle into the film. Now, you do have to be smart about where you put the lamps. SWIR only works if it has a clear line of sight. If your part has deep pockets or a weird shape, you’ll end up with cold spots. You’ve got to map out the lamp array carefully so the heat hits every single surface at the right angle. The result? You get rid of that annoying “orange peel” look and those tiny bumps caused by dust. Plus, it’s just faster. You aren’t sitting around waiting for a massive room to warm up. You just flip the switch and start curing. Your equipment takes up less space, and you stop throwing away ruined parts.

Preventing Structural Deformation in Satellite Reflector Curing via Short Wave IR Heating

The Trick to Curing Ultra-Light Satellite Parts Without Ruining Them

When you’re dealing with anti-corrosion coatings on satellite antennas, you run into a real headache: how do you bake the coating without warping the whole damn thing? See, these ultra-light composite structures have almost no thermal mass. If you throw them in a convection oven or try some slow-ramp heating, the heat just soaks right into the core. Before you know it, the structure starts to sag or shift under its own weight. It’s a nightmare. Why we stick with short-wave IR We use short-wave infrared lamps because they’re surgical. Instead of heating the whole room, they target the coating. The radiation hits the surface and turns into heat instantly. It’s basically a “flash cure.” You get the polymers to cross-link at the surface exactly how they need to, but the actual reflector underneath stays cool. This keeps the structure stable and prevents any deformation. Dealing with heat density You can’t just blast these things with power, though. If you do, you’ll get hotspots that burn right through thin-film coatings. We spend a lot of time dialing in the wattage-per-centimeter. It’s all about the distance between the lamp and the reflector—that’s how you control the intensity. If you cram too much power into one small spot, you’ll see bubbles. It’s a delicate balance between how hot the lamp is and how fast the part is moving on the conveyor. The messy side of integration Actually setting these heaters up takes some planning. You need a rigid frame, and since those short-wave lamps get incredibly hot, you have to vent the housing. If your cooling fans aren’t up to the task, the housing itself will warp. Once that happens, your focal distance is shot, and you’ll end up with uneven curing across the surface. Oh, and a pro tip: use high-temp silicone leads for the wiring. Otherwise, the insulation will just melt right off near the quartz tubes.

Optimizing Aircraft Skin Paint Leveling via Targeted Infrared Drying

Getting a Mirror Finish on Aircraft Skins with IR Drying

Ever deal with that frustrating “orange peel” look or those tiny solvent pops on a fresh paint job? It usually happens because of how traditional convection ovens work. They heat the air, the air heats the skin, and the surface basically “skins over” too fast. The solvents trapped underneath have nowhere to go, so they fight their way out, leaving you with a finish that looks like a basketball. We do things differently. We use shortwave infrared (IR) lamps that go straight through the coating. How it actually works Think of it as heating from the inside out. Instead of waiting for hot air to drift around, the IR energy hits the aluminum and the paint at the same time. This is the secret sauce. Because the paint stays liquid a bit longer, the resin has time to actually flow and flatten out. By the time the final cure kicks in, the paint has already leveled itself. That’s how you get that glass-like, mirror finish without the headache. The tricky part: Getting the heat right You can’t just blast it with heat and hope for the best. If you put too much wattage into one small spot, you’ll scorch the surface. It’s all about balance. We tweak the voltage and wattage so the heat is steady, even as the wing curves away from the lamp. You also have to be obsessive about the distance. Seriously—if your lamp is off by just a few centimeters, you’re looking at hot spots. The reality check Here is the best part: it’s fast. Like, really fast. We’re talking about cutting cure times by 60% to 80%. Your workflow moves way quicker. But there’s a catch. IR is line-of-sight. If your wing has deep recesses or weird geometry, the lamps simply can’t “see” those spots. To fix that, you’ll still want a bit of ambient heat or a secondary source so those shadowed areas don’t stay tacky. And one last tip: make sure your controllers are set for a gradual ramp-up. You don’t want to shock the metal with a sudden spike in temperature.
