Technical Information Underbody Protection Bitumen

Technical Information Underbody Protection Bitumen

presto Underbody Protection (Bitumen) forms a visco-plastic, durable sealing on the underside of machines, vehicles and wheel cases of all types of motor vehicles. It protects the underbody from mechanical and chemical stress like stone chipping, road salt, water, rust and the weather-influences.

Thixotropic properties mean the spray can be applied in thick layers without running.

For use on bodywork, in workshops, bus construction, at home

Available in 500ml spray cans and also in 1 litre spray gun cans as well as in 1.3 kg and 2.5 kg brush paint cans.
