SILFOAM® SD 168
SILFOAM® SD 168 is a very compatible, anhydrous antifoam agent that is easily disperable. SILFOAM® SD 168 is intended for incorporation into non-structured liquid detergents for foam control and polymer dispersions (latices) in order for deaeration.
All the information provided is in accordance with the present state of our knowledge. Nonetheless, we disclaim any warranty or liability whatsoever and reserve the right, at any time, to effect technical alterations. The information provided, as well as the product's fitness for an intended application, should be checked by the buyer in preliminary trials. Contractual terms and conditions always take precedence. This disclaimer of warranty and liability also applies particularly in foreign countries with respect to third parties' rights.
By virtue of its chemical structure, SILFOAM® SD 168 is capable of regulating surfactant-based formulations, in particular liquid detergents insufficient alkali resistance or rapid loss of effect are significantly reduced. Its principal areas of application are in non-structured liquid detergents and cleaners.
When introduced into dispersions SILFOAM® SD 168 shows relatively good compatibility with the polymer film and high efficiency during storage, especially at higher temperatures. Typical applications of SILFOAM® SD 168 are all kinds of dispersions, especially for the construction industry, masonry paints and adhesives.
SILFOAM® SD 168 is usually added undiluted to the foaming formulation in amounts of 0.2 - 1.0% at the end of the product formulation stage. SILFOAM® SD 168 usually disperses without the need for high shearing forces and is stirred in gently.
We recommend conducting compatibility tests before the antifoam agent is incorporated into a liquid formulation or dispersion. Approx. 0.5 % SILFOAM® SD 168 is gently stirred into a small amount of the foaming medium. If the mixture does not separate,SILFOAM® SD 168 can be subjected to further application tests.
The 'Best use before end' date of each batch is shown on the product label.
Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
