Körapur™ Polyurethane Adhesives

Körapur™ by H.B. Fuller is a versatile range of polyurethane adhesives and sealants, available in single-component (1K) and two-component (2K) versions. Designed for technical assembly in sectors such as construction, marine, automotive, and industrial, it offers specific solutions for every need: from Körapur 645, ideal for fixing fiber mesh on tiles without sticky residue, to Körapur 672, IMO certified for marine and structural applications.

The marine range includes 925, 928, and 940 Marine, silane-modified formulations for marine use: non-sagging, high elasticity, and resistance to moisture, UV, and extreme temperatures (–40 °C/+90 °C). Finally, Körapur 125 is a multi-purpose non-sagging solution, weather-resistant and suitable for food contact.
