Concrete Waterproofing Agent

Product Name: Concrete Waterproofing Agent

Item No: SilibaseWR-4004

Introduction:

SilibaseWR-4004 Concrete Waterproofing Agent is a 40% active nonionic emulsion containing alkoxysilanes. Silanes are well known for their ability to provide hydrophobicity and decrease dramatically the water ingress of cementitious materials. Silane supplied in emulsion can chemically react with cement hydrate during cement cure. Alcohol is released upon reaction of the silanes. 

SilibaseWR-4004 Concrete Waterproofing Agent is a water-based silane emulsion which can be used as admixture in cementitious materials. 

Silanes react chemically within the cementitious matrix and provide integral water repellent treatment 

Treated cement-based materials are resistant against water absorption throughout the material. 

As a water-based emulsion, SilibaseWR-4004 Concrete Waterproofing Agent provides easy incorporation of silanes in cement-based slurry. 

SilibaseWR-4004 Concrete Waterproofing Agent can be used as supplied or diluted in water prior to addition in cement slurry.

Chemical Name: Silane / Siloxane Emulsions

Benefits:

When used as an additive to cementitious matrix, silane emulsion can impart the following benefit to the final material: 

Significant reduction in capillary absorption of water. Little to no reduction of water vapor permeability. 

Significant reduction of ingress and transfer of water-soluble salts through the matrix (i.e. efflorescence). 

Reduction of water uptake is resistant to UV exposure.

Typical Physical Properties:

Color and Appearance: Milky White Liquid

pH:6~7

Active Ingredient: 40%

Application:

It is advised to stir SilibaseWR-4004 Concrete Waterproofing Agent prior to its application. 

SilibaseWR-4004 Concrete Waterproofing Agent can be used as supplied or can be diluted in water before use. The water should be added to the emulsion with low shear mixing. Deionized water is recommended for dilution. After dilution, it is advised to make sure the pH is maintained in the 5-9 range. To prevent mold growth within the package, additional preservative may be required if the diluted emulsion is expected to be stored. 

SilibaseWR-4004 Concrete Waterproofing Agent can be used as an admixture to cementitious mixtures at levels between 0.2 to 0.5% by weight of SilibaseWR-4004 Concrete Waterproofing Agent as supplied based on the dry composition weight. 

If calculated to cement mass, an addition level of SilibaseWR-4004 Concrete Waterproofing Agent between 1 and 2% vs cement is advised. 

It is however strongly advised to carry out an evaluation of SilibaseWR-4004 Concrete Waterproofing Agent addition on the physical properties of the targeted cement-based materials prior to any use in full scale application. 

SilibaseWR-4004 Concrete Waterproofing Agent is used as a surface modifier to generate hydrophobictity (e.g. concrete, glass, inorganic pigments, or mineral fillers). 

Packing and Storage:

SilibaseWR-4004 Concrete Waterproofing Agent is supplied in 200Kg steel drum or 1000Kg IBC tote.  

In the unopened container SilibaseWR-4004 Concrete Waterproofing Agent has a shelf life of 6 months. 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.
