A UV-curable, cured-in-place gasket (CIPG) technology, Vitralit^® CIPG 60200 from Hoenle consists of a blue fluorescent polyacrylate sealing material specifically engineered for high-performance electronic housings in automotive and e-mobility applications. It is a CMR-free polyacrylate formulation that can be precisely dispensed using adhesive dispensing valves and programmable robots. This ensures accurate bead geometry and excellent dimensional stability in the uncured state.

Rapid curing under UV light (LED at 365 nm or 405 nm, or gas discharge lamps) enables short cycle times and immediate handling strength.

Once cured, Vitralit CIPG 60200 ensures reliable joint tightness upon compression, effectively preventing leakage of fluids and gases. Even under elevated temperatures, the gasket maintains high elastic recovery. A compression set of only 15% after 24 hours at 150 °C (ASTM D395-B) demonstrates its strong repulsive force and long-term sealing capability. The operational temperature range extends from – 40 °C to above 150 °C.

The cured gasket exhibits outstanding chemical resistance against typical automotive media, including engine oil, automatic transmission fluid (ATF), and water/glycol mixtures (50:50). Low outgassing characteristics make Vitralit CIPG 60200 particularly suitable for sensitive electronic components. The product is UL 94 HB compatible, meeting established flammability standards for polymeric materials.

Thanks to its high temperature and mechanical resistance — under both static and dynamic loads — the CIPG represents a reliable alternative to solid gaskets and FIPG (RTV silicone) systems, particularly in demanding automotive environments.

This new versatile sealant is ideally suited for sealing housings of:

• ECU (Electronic Control Units)
• BDU (Battery Disconnect Units)
• OBC (On-Board Chargers)
• CMC (Cell Module Controllers)

It provides immediate protection for sensitive electronic assemblies against dust, moisture, and harsh chemicals after UV curing.

In addition to performance benefits in series production, Vitralit CIPG 60200 is specifically designed for maintenance, repair and overhaul (MRO) scenarios. Unlike conventional single-use gaskets, the cured material can be reused after disassembly, allowing housings to be opened and resealed without gasket replacement. This reduces service costs, minimizes waste, and improves overall system sustainability.
