Water repellents are used to provide buildings and roads with durable protection against water and moisture. Our silicone-based water repellents minimize the infiltration of water and dissolved pollutants, while maintaining the water vapor permeability at the same time.
Important requirements for water repellents:
- High degree of alkaline stability
- Permeability to gas and water vapor
- Low surface tension
- No sticky surfaces
- Deep penetration depth
Improved protection from efflorescence and increased freeze-thaw (salt) resistance
Flawless building surfaces are an important feature of high quality aesthetic architecture. Unsightly crystalline efflorescence can often appear on the surface of structures.
