Acronal S 400 has a varied range of

uses.

Areas of application include for example:

basecoats high-flexibility tile adhesives rigid and flexible waterproofing

slurries for sealing in conjunction

with tiles and protective surface

coatings

anticorrosion protection additive for hydraulic binder systems roof coverings

P r o c e s s i n g

It is usually not necessary to add any

plasticizer, because Acronal S 400 has

low film-forming and glass transition

temperatures.

If the air voids content increases during

processing of Acronal S 400, we

suggest defoaming tests with, for exam-

ple, 0.3 1.0 % Lumiten E 3065 or

Lumiten E-L.

To ensure the crack-bridging proper-

ties of mineral waterproofing slurries,

the polymer/cement ratio should be

between 0.6 and 0.8. If a sag-resistant

consistency is required for the pro-

cessing rheology of the slurry, we

recommend the use of polyurethane-

based thickeners like, for example,

Collacral PU 75.

To speed up hydraulic formulations with

a high proportion of polymer, it may be

beneficial to add aluminous cement or

calcium formate to the dry component.
