Sprayable polyurea KALEA

Sprayable Polyurea-based wear protection for pipes and plant components

KALEA is a durable, high-performance polyurea-based plastic that is characterised by high wear resistance. KALEA is spray-applied and cures extremely quickly. A separate corrosion protection layer is unnecessary. 

As such, the material is particularly well suited for seamlessly lining plant components with large surface areas, such as coal, ore and sand bunkers as well as lining silos and tanks, chutes and troughs. 

The material has a high rebound resilience. The weather- and temperature-resistant surface protection also has a sound-absorbing effect. The key benefit offered by KALEA is in increasing operational reliability and extending the service life of plant components.
