With the name Sitren AirVoid® our supplier EVONIK supplies us with a wide range of defoamers for dry mortars. These additives selectively combat all air bubbles created during processing and help to improve temperature resistance, substrate adhesion, aesthetics and mechanical properties of the mortar. In addition they do not affect the curing.
Among the defoamers there are products based on polyethers, organo modified siloxanes or acetylenic diols (Gemini surfactants). All defoamers are supplied in powder form (coated on inorganic material).
Areas of application are repair mortars, tile adhesives, levelling compounds or renders.
