Silway 7289 Resin admixture is an alkyl
functionalized, low viscosity silicone resin.
Upon proper mixing of the product into
cement-based formulation, it will disperse
into the water-based slurry.
Addition of Silway 7289 Resin provides
hydrophobicity and decreases dramatically
the water ingress of cementitious materials
in which it isincluded. Alkoxysilyl chemical
group in the resin can chemically react with
cement hydrate during cement cure.
Alcohol is released upon reaction of the
resin.
This product can be used in many
application areas where the protection of
the substrate from liquid water ingress is
required.
Clear, low viscosity fluid which can be
used as an admixture in cementitious
materials
Reacts chemically within the
cementitious matrix and provides
integral water repellent treatment
Treated cement-based materials are r
esistant against water absorption
throughout the material
Reduction in capillary absorption of
water
Reduction of ingress and transfer of
water-soluble salts through the matrix
and related aesthetic problems such as
efflorescence
Releases little Volatile Organic Content
(VOC) upon reaction
Admixture for cement-based
construction materials with improved
water resistance (Fiber reinforced
cement boards or prefabricated building
components such as autoclaved
lightweight cement)
Silway 7289 Resin should be used as
supplied. Do not dilute in solvents prior
to use.
Depending on final requirements, Silway
7289 Resin can be used at levels ranging
from 0.1 to 0.5%. Prior testing and
evaluation are required to ensure
optimum addition level for maximum
water repellency and a minimum
potential impact on the other board
properties.
Determination of optimum addition levels
should be evaluated in the laboratory
before any production scale evaluation.
