Original product description

Solventless Silicone resin based long life span Mansory Water Repellent Sifs-290 SiFS-290 is a solvent-free silane and siloxane concentration blends. It is dilutable with organic solvent. It can penetrate inside the building substrate to form an efficient and lasting water-proofing layer protection.

Diluted solutions of SiFS-290 in organic solvent serves as a high-efficient, general-purpose water repellents for impregnating and priming mineral and alkaline substrates.

Features • Good penetration with depth 3-10mm • Extremely effective with most natural stone • good alkali resistance SiFS-290 reacts with the atmospheric moisture or pore water in the substrate, thereby generating the active ingredient while releasing alcohol.

It can penetrate inside the building substrate to form an efficient and lasting water-proofing layer protection, which nevertheless retains a very high degree of water vapour permeability since neither pores nor capillaries are clogged.

P roduct data Item Value Appearance Hazy and colorless liquid Active Content,% 100 Density, g/cm 3 0.92±0.05 Notes: these data are for reference only and should not be used as preparation specifications.

Application SiFS-290 is suitable for imparting hydrophobicity to absorbent, porous, mineral construction materials, e. g.: brickwork, all kinds of concrete , aerated concrete, sand-lime brickwork, cement fiber boards, mineral plasters,mineral-based natural and artificial stone, mineral paints.

It is also suitable as primer for exterior paints. How to use • Clean and dry the substrate. • Dilute SiFS-290 with ratio around 1:12, solvent could be alcohol, hydrocarbons or petroleum. • Spray or brush, recommended dosage of 5L/m 2 , adjust dosage according to different substrate.

The trial test is recommended for optimum dosage. Package 25L plastic pails, 200L Drums or 1000L IBC totesNet weight 20KG/pail,180KG/drum and 900KG/IBC.

ABOUT SILICONE WATER REPELLENT Silicone waterproofing agent: A series of chemicals/mixtures which containing Si-O bonds and alkyl groups (like methyl, octyl group) in the molecular structure.

The machanism of silicone water repellent: The SiOH (silicon hydroxy) group react with the substrate to form a thin resin film: • The silane reacts with water (Hydrolysis reaction) to form SiOH (silicon hydroxy) group and it is can be bond to the OH (hydroxy) of the substrate. • The silanes occurs
