ETONIS® 7260 A
ETONIS® 7260 A is a ready-to-use polymer dispersion for special concrete applications, especially for open-pored concrete (sound-absorbing and pervious concrete).
In the mixing stage, ETONIS® 7260 A may be blended with fresh concrete either directly or together with the mixing water. ETONIS® 7260 A allows low water/cement ratios to be used and its stabilizing effect means segregation of the concrete does not occur during processing. Adjustments to technical requirements are necessary at the construction site. Mixing facilities, transport trucks and other equipment are simply cleaned with water. When calculating the water/cement ratio, add the water content of ETONIS® 7260 A to the mixing water content of the concrete. When used as a bonding course, ETONIS® 7260 A should be applied to a well prepared (milled, blasted) substrate that is almost entirely dust free. ETONIS® 7260 A is sprayed, brushed or rolled on as a thin, uniform layer (dilution with water is possible). Once film formation is complete, the bonding course becomes transparent and the fresh concrete can be applied. Film formation is by drying, which usually takes a few hours (depending on weather conditions). As a result, preparing the bonding course is decoupled from installing the fresh concrete.
ETONIS® 7260 A is particularly suitable in open-pored concrete (water-permeable, no-fines concrete), for both the bottom and top concrete courses. ETONIS® 7260 A is also suited as a bonding course between fresh concrete and hardened concrete (e.g. in whitetopping).
If the product is used in applications other than those mentioned, the choice, processing and use of the product is the sole responsibility of the purchaser. All legal and other regulations must be complied with.
