StenSilan® WO is a single-component, solvent-borne, silane-based water and oil repellent impregnation agent. It chemically bonds to mineral surfaces such as concrete, plaster, aerated concrete, natural stone and ceramic, penetrating deep into the material without forming a film to give it a hydrophobic and oleophobic character. Treated surfaces do not get wet or soiled by water, oil and similar liquids, and any residue wipes away easily. Because it forms no separate layer, it carries none of the peeling, separating, embrittlement or slipperiness risks of other impregnation-type materials.
Areas of Use
StenSilan® WO prevents gas-permeable, breathable mineral surfaces such as concrete, plaster, aerated concrete, natural stone and ceramic from absorbing water and oil. It forms a hydrophobic and oleophobic structure even on micro-crack surfaces and does not allow liquids to enter the structure. It is ideal for protecting floors in workshops, repair shops and factories where staining contaminants that deteriorate concrete are present. Since it does not clog capillary canals it does not impede the structure from breathing or transmitting gases, and by preventing water in capillary cracks from freezing and deforming the surface it prolongs coating life. It is used to protect any concrete or mineral surface exposed to atmospheric conditions and the wetting effect of rain water.
Features & Advantages
- Solvent-borne, single-component, silane-based, low-viscosity transparent fluid
- Very high surface covering and penetration into the material
- Creates a deep hydrophobic and oleophobic structure without a film layer
- Lets the surface breathe and preserves its natural appearance
- Liquids on the surface wipe away easily and leave no stain
- Resistant to UV radiation and increases the durability of the coated surface
- Improves the paintability of the coated surface
- Prevents salt efflorescence on absorptive surfaces during drying
- Can be applied by spraying or with brush and roller
- Maintains protection for 5-10 years depending on penetration depth and surface abrasion
