Product description
SILRES® BS 1340 is a nonionic, solvent-free, water
dilutable emulsion of a reactive polysiloxane.
Application
SILRES® BS 1340 is used in undiluted form as a
hydrophobizing additive for aqueous masonry paints or
plasters to increase water repellency, water resistance
and water vapour permeability as well as to enhance
processability and anti-blocking properties.
Suitable for:
- silicone resin emulsion paints and
silicone resin emulsion plasters
- silicate emulsion paints and plasters
- highly-filled emulsion-based coatings
- emulsion-modified whitewash
- stoppers
Paints and plasters modified SILRES® BS 1340 are
characterized by an excellent water beading effect.
Processing
SILRES® BS 1340 can be added in undiluted form to
aqueous masonry paints or plasters during or after
their production. The addition of 1 to 3 wt.-% is
recommended.

for the intended use must be checked for quality
assurance reasons.
