Product Description

Product Description

Silway 715 is an aqueous solution of potassium methyl siliconate and is used in diluted form for the hydrophobic impregnation of mineral construction materials to make them water-repellent.

Silway 715 develops its water-repellent properties by reaction with atmospheric carbon dioxide (CO2). The active substance formed from the silicone masonry water repellent is polymethylsilicic acid. As with all siliconates, however, Silway 715 can cause a white deposit on the surface of colored construction materials, or if used outside the application guidelines.

Product Parameters

 

Appearance	clear to hazy, colorless to  slightly yellowish
Solid Content	52-54%
Active content	32-36%
K2O equivelent	17-20%
pH	13

Products Feature

Excellent water resistant, reduce water absorption into the substrate, thus reducing spalling due to freeze-thaw and efflorescence, thereby increasing the life of the substrate.
Colorless protection, preserve the natural appearance of the substrate.
Penetrating and breathable.

Typical applications

• Low-fired clay products immediately after they have been made: roof tiles, facing bricks, floor tiles, flower pots
• Aerated concrete
• Gypsum and gypsum-based fiber boards
• Iight fillers, such as perlite, vermiculites and aerated concrete granules
• Insulating materials

Usage

For surface treatment, dilute Silway 715 21-25 times with water.First clean up the dust and oil of the substrate surface, then spray the diluted water repellent on the substrate surface. Cured the substrate for at least 1 day.
Impregnate tiles processing, dilute Silway 715 60 times with water, then impregnate tiles into the diluted water repellent for 60s. Cured the substrate for at least 1 day.

Preliminary tests are always required for the determination of the correct dilution ratio.

Storage

Silway 715 must be stored in the tightly closed original container.

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.

Silway 715  should be stored in stainless steel drums, plastic or glass containers. Tinplate, aluminium or galvanized or lacquered containers are not suitable. If crystals are formed due to too low storage temperatures, these will redissolve when the product is allowed to warm up. The product must then be stirred thoroughly.
