Körapop™ MS Adhesives and Sealants

Körapop™ adhesives and sealants by H.B. Fuller represent a range of high-performance MS adhesives, designed for industrial technical bonding. Available in single-component (1K) and two-component (2K) versions, they combine elasticity, UV and weather resistance, and compatibility with materials such as metals, glass, wood, and plastics—all without the need for primer.

Körapop™ excels in applications for HVAC, automotive, caravans, and industrial machinery. For example, the 225-2K version, composed of a silane-reactive base, ensures extreme flexibility and moisture resistance, even when combined with a booster for adaptable pot-life times.

Alternatively, single-component solutions like Körapop 250, 240, 330, and Transparent offer high adhesion, high elasticity, various colors, and rapid skin formation, ideal for bonding, sealing, and aesthetic applications where transparency or a clean finish is crucial.

Application Versatility

Körapop™ is designed to adapt to different industrial processes, thanks to tailor-made formulations for specific performance.

Common Applications:

Sealing/bonding in HVAC, recreational vehicles, and caravans (225-2K)
Metal-plastic-auto assembly, light construction (250, 240)
Transparent integration for glass, light panels (Transparent)
Quick and clean notch for hot bonding or assembly activities

The range covers both aesthetic needs (transparency, color) and functional needs (elasticity, environmental resistance).
