SILFOAM^® SD 169

By virtue of its chemical structure, SILFOAM^® SD 169 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 169 shows relatively good compatibility with the polymer film and high efficiency during storage, especially at higher temperatures. Typical applications of SILFOAM^® SD 169 are all kinds of dispersions, especially for the construction industry, masonry paints and adhesives.

Processing

SILFOAM^® SD 169 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 169 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 169 is gently stirred into a small amount of the foaming medium. If the mixture is stable, SILFOAM^® SD 169 can be subjected to further application tests.
