Sprayable polyurea

Sprayable Polyurea-based wear protection for pipes and plant components. KALEA is an elastomer system – which can be applied by injection molding – for protection against abrasive wear. KALEA is especially suitable for slide promotion.


KALEA is a durable, high-performance polyurea-based plastic that is characterized 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.
