SILRES® BS 5350

1 of 110 products in this brand
SILRES® BS 5350 is a pure liquid siloxane specifically designed to provide water repellency to autoclaved aerated concrete (AAC) and effectively reduce its capillary water absorption. It is suitable for application on AAC with densities above 150 kilograms per cubic meter. Despite being a non-water-based product and free from surfactants or solvents, SILRES® BS 5350 is commonly used as an integral or in-mass hydrophobizing additive in the aqueous AAC slurry. It disperses within the mixer through the shear forces generated between the liquid and solid components.

Application Details
  • SILRES® BS 5350 is used as a so-called integral or in-mass hydrophobizing additive, which means that it is added to the water-based AAC slurry already at the slurry mixer. A common dosage level is 0.2 % by weight based on the overall solids in the AAC slurry.
  • Nevertheless, depending on the type of recipe and the produced density, orientating trials should preferably start at a dosage level between 0.1 and 0.15 % in order to ensure sufficient green strength.

Properties
  • Even though SILRES® BS 5350 is not water-based and contains no surfactants or solvents, as a so-called integral or inmass hydrophobizing additive it is commonly used in the aqueous AAC slurry and disperses by the shear forces between liquids and solids in the mixer.
  • SILRES® BS 5350 can strongly reduce the water absorption of AAC (determined according to EN 772-11), but in contrast to other hydrophobizing additives at the same time has only neglectable influence on compressive strength and pore size distribution or thermal conductivity. No noteworthy influence on green strength has been observed in the recommended dosage range.
  • Furthermore, no negative effects on the adhesion strength of cementitious AAC thin bed adhesives have been observed.
