We are offering Silicon Water Repellant - Literature Hydriphobe 902.hydrophobe 902 is the masonry 100% water repellent made of reactive silicone, based on silane/siloxanes. this organic solvent provides colorless surface finish to mineral construction material while maintaining enough water vapor permeability.
literature hydrophobe 902 is perfect for coating painted surfaces as substrate color is not changed on application. within 24 hours of application, the literature hydrophobe 902 creates water repellence which improves after a week.
advantages - high penetration in mineral building materials that are absorbent
- highly resistant to alkalis
- cures quickly to impart water repellence
- works on damp surfaces as well
- no problem of freeze-thaw damage, cracking, scaling, chemical degradation and dirt pick up, so substrate life is improved and maintenance cost is reduced
- pores and capillaries are not sealed so breathability is maintained
- creates uv stable and biological resistant coatings
usage instructions the chemical reacts with the moisture in atmospheric to generate active resin and releases alcohol. the active ingredient formed imparts excellent water repellence to the substrate and to absorbent, porous & mineral construction materials like:
- brick works
- mineral based natural and artificial stone
- aerated concrete
- cement fiber boards
- mineral paints & plasters
how to use dilute1:20 (parts by weight) with suitable diluents like aliphatic hydrocarbons (white spirit boiling point 135-175oc) and low odour iso paraffin hydrocarbons or aromatic hydrocarbons (solvent naphtha). ethanol or 2- propanol can be used as well where solvent sensitive materials are to be impregnated. dilute with some stirring to dissolve spontaneously. appearance will not change until the pot life gets expired but use the solution within 24 hours. excellent results are obtained, when this is diluted with suitable solvent in a ratio of 1:15 to 1:25, and when the diluted solution is used on the day of dilution. although the coverage could be in the region of 125 -150 sq meters, it depends on the surface absorbance. the substrate should be air dry and absorbent. the diluted solution should be liberally applied in at least two coats, wet on wet, to the surface of material by brushing, spraying or flooding (flooding or spraying is preferable). before application, ensure to cover windows and other non-absorbent surfaces properly as the product cures quickly and therefore it is very difficult to remove it after a few days. wipe off any splashes on windowpanes immediately using soapy water, or if necessary, an organic solvent.
