SILRES® BS 1803

SILRES® BS 1803 is a solvent-free emulsion based on organo-modified silanes and siloxanes.

 


Properties

SILRES® BS 1803 can be used as water repelling admixture for semi-dry concrete and other non-load-bearing cement based building materials (e.g. paving stones, concrete blocks)

 

  • greatly reduces water absorption
  • very good water beading
  • protection against de-icing salts
  • efflorescence reduction
  • water vapor permeable

Stir product before use.

The recommended admixture range is 0.1 to 1.0 % of the cement content. A significant reduction in water uptake can be achieved at a concentration of 0.2 %. For post-treatment a 1:4 solution can be recommended to reduce water uptake significantly.

When used as an admixture in semi-dry concrete SILRES® BS 1803 produces a matrix that resists water absorption without blocking pores or capillaries. The treated concrete inherently resists intrusion of damaging water and chemicals increasing the service life of the building material. SILRES® BS 1803 prevents or at least reduces efflorescence. A strong water beading effect occurs throughout the whole concrete block.

Storage

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.
