About celotec
celotec GmbH & Co. KG, based in Sendenhorst, is a manufacturer of high-quality painted surfaces on film products. The company is a spin-off of VEKA AG and part of the Laumann Group. Its core is a roll-to-roll coating line with an integrated electron beam (E-Beam) unit, with which plastic films up to 1650 mm web width are coated and irradiated. The electron-beam-cured (ESH) paint surfaces give the decorative films high weather, scratch and abrasion resistance for exterior construction applications. With the product lines spectral (Exterior) and celobon (Interior), window and door profiles, entrance door infill panels, garage doors and façade elements are finished. The in-house laboratory celolab offers surface analysis, environmental simulation and testing services as well as customer-specific paint development. External film irradiation (crosslinking, polymerisation, sterilisation) and film cutting are also offered as services.
