It&rsquo;s the classic bottleneck. The goal is simple: you want to run that web faster to bump up your margins, but you can&rsquo;t just crank the heat. If you do, you ruin the slurry. That&rsquo;s where Near-Infrared (NIR) lamps come in.</p> <h2 id="why-nir-actually-works">Why NIR actually works</h2> <p>Most heat sources just bake the top layer. It creates a &ldquo;skin&rdquo; on the surface that traps solvents underneath, which leads to cracks and a lot of wasted material. It&rsquo;s frustrating. NIR is different. It reaches deeper into the coating. Instead of just searing the top, it lets the solvents move to the surface and evaporate evenly. Because it hits that 0.7 to 1.4 $\mu$m wavelength, you hit your target temperature way faster.</p>
