Test section of drainage concrete. While the water builds up on normal concrete or asphalt and runs off slowly (right side of photo), it can drain away easily and quickly on the new drainage concrete (left).

Drainage concrete modified with ETONIS^® 260 is spread between and beside tracks and thus provides rescue vehicles and fire trucks with fast access to rail-road tunnels. The new concrete is quick to put down, extremely durable and stable, and thus ideal for applications in road, tunnel and under-ground construction (photo: Wacker Chemie AG, courtesy of Deutsche Bahn AG).

Freshly mixed drainage concrete in laboratory trials: the open-pored structure and pores can be clearly seen. Thanks to the new ETONIS^® 260 polymer, the non-slump fresh concrete does not flow or disintegrate at the edges – this is a vital prerequisite for level track surfaces.

Lab test of a dispersion: Depending on the formulation, VINNAPAS^® LL 3112 allows highly fire-resistant coatings with fire resistance class F120 to be achieved, which means heat protection for up to two hours.

In case of a fire, intumescent coatings foam to tens to hundreds of times its original thickness and act as a heat barrier. The new VINNAPAS^® LL 3112 binder ensures significant foam development in these coatings, coupled with improved adhesion and strength (photo: Clariant Produkte Deutschland GmbH - 2013).
