SILRES® BS 1703 SQ

SILRES® BS 1703 SQ is intended primarily for in-plant water-repellent treatment of fiber-reinforced cement-products, like e.g. fiber-cement board. It significantly reduces the capillary water absorption of the construction materials after setting and reaching equilibrium moisture.

SILRES® BS 1703 SQ exhibits a higher flash point and increased storage stability compared to SILRES® BS 1703.

SILRES® BS 1703 SQ is a clear to slightly opalescence pure siloxane with colorless to slightly yellowish appearance. A slight yellowish discoloration may seem more pronounced in IBC, but does not influence the excellent performance of the product. 



Properties

SILRES® BS 1703 SQ is a liquid but waterless oligomeric siloxane of a relatively low viscosity. It is not water-thinable, but intended to be used in water-based construction material processes involving high-shear mixer units, especially for manufacturing fiber-reinforced cement-products, like e.g. fiber-cement board. As an admix additive for the integral water-repellent treatment, it is usually added undiluted into the mixer.

The information provided, as well as the product's fitness for an intended application, should be checked by the buyer in preliminary trials. Contractual terms and conditions always take precedence. This disclaimer of warranty and liability also applies particularly in foreign countries with respect to third parties' rights.

SILRES® BS 1703 SQ is added undiluted into the mixer, usually at dosage levels ranging from 0.1 to 0.3 % by weight based on the overall solids level. For the unimpaired product performance, proper mixing into the cement-based slurry is required. The product should be added to the slurry after all solids, especially cement.

 

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.
