insulbar with ESPOC: high-quality coating for insulating profiles
Ensinger to present award-winning product at BAU 2025
Ensinger has developed a new technical solution for the powder coating of insulbar window and door profiles. The innovative ESPOC technology (Electrostatic Potential Optimized Coating) is based on a thin, electrically conductive layer which can be applied both to standard insulating profiles and customised profile designs.
Regardless of the moisture content of the profiles treated with ESPOC, the electrostatic attraction of the powder remains at constantly high level during the coating process. As a result, optimum coating can be achieved even on dry profiles, and the “blistering effect” can be eliminated. “By preventing the formation of bubbles in the coating process, the quality of the finish on window and door profiles can be significantly improved”, explains Matthias Rothfuss, Head of insulbar Application Engineering, Product Management & Marketing. “With the ESPOC method, both aluminium-plastic assembled profiles and individual polyamide insulating bars can be optimally coated, resulting in an outstanding appearance in both cases.”
The coating is based on an innovative technology and stands out for its chemically stable, firmly adhering surface. This characteristic permits the uniform powder coating even of complex geometries such as protrusions and undercuts.
The recyclability of the plastic profile material is not negatively affected by the coating. Hence the technology combines a high-quality look and technical functionality with environmental compatibility and sustainability.
In October, Ensinger received the Cham district’s innovation award in recognition of its development of ESPOC technology, for which a patent application has been filed.
Ensinger at BAU 2025
Visitors to the leading international trade fair BAU (Munich, 13 -17 January 2025) can find Ensinger in Hall B1. At Stand 438, the insulbar business division will be presenting the ESPOC technology and additional innovations for the window and door market.
