Sealing Systems for Industrial Lighting
Maximum Safety. Outstanding Optical Performance.

Your Challenge
Components of industrial lighting systems are subject to constant stress from dust, moisture, and aggressive cleaning agents that continuously act on the housings. Dust, moisture, and aggressive cleaning agents continuously affect the housings. At the same time, optical systems require extremely clean and stable sealing lines, while assembly processes must be fast, automatable, and completely error‑free. Varying geometries and materials further complicate reliable, consistent sealing.
Our Solution
Sealing systems for industrial lighting that are precisely tailored to your housing geometries. Using liquid to highly thixotropic two‑component systems based on RAKU® PUR, RAKU® SIL, and RAKU® SEAL, we deliver maximum sealing performance, outstanding optical quality, and efficient series production – from small batches to high‑volume manufacturing.
