Core offering

Sonderhoff Chemicals develops and manufactures polyurethane-based foam sealing, adhesive (bonding), and potting material systems together with the proprietary mixing and dosing equipment required to apply them via Formed-In-Place Foam Gasket (FIPFG), Formed-In-Place (FIP), and MOLD'n SEAL processes. The company also operates contract manufacturing service centers that produce gasketed, bonded, or potted components on behalf of industrial OEM customers.

Product overview

Sonderhoff Chemicals, operating as a Henkel Adhesive Technologies brand since January 2020, offers an integrated technology platform for customized automated sealing, bonding and potting solutions. The portfolio consists of three core pillars: (1) Material Systems including FERMAPOR K31 polyurethane sealing foams, FERMADUR potting systems, FERMASIL silicone systems, FERMAPOR CC closed-cell foams, and specialized variants (FOOD CONTACT, FAST-CURE, LOW-EMISSION, MICROBIAL INERT, FLAME PROTECTION); (2) Engineering Systems comprising mixing and dosing machines (DM 502/503/504, DM 90, DM 80, DM 70) and dosing cells (3E, SMART-M/L); and (3) Process Technologies including FIPFG gasketing, FIP potting, FIP CC closed-cell, and MOLD'N SEAL combined processes. The offering is complemented by digital services (Performance & Maintenance Hub with IoT monitoring, AI Service Assistant) and contract manufacturing services.
