silway 7289
Silway 7289 is an alkyl functionalized silicone resin.

Upon proper mixing of the product into cement-based formulation, it will disperse into the water-based slurry.
 
Silway 7289 Silane polymer, a waterproofing agent designed for constructions
 
As a water repellent for construction materials, this product is a highly effective waterproof agent and can be widely used in many fields where it is necessary to protect the substrate from liquid water ingress. It is an ideal waterproof solution for various construction materials, effectively enhancing the protection against moisture penetration.
 
Key Features
  • Clear, low viscosity fluid which can be used as an admixture in cementitious materials
  • Reacts chemically within the cementitious matrix and provides integral water repellent treatment
  • Treated cement-based materials are resistant against water absorption throughout the material
  • Reduction in capillary absorption of water
  • Reduction of ingress and transfer of water-soluble salts through the matrix and related aesthetic problems such as efflorescence
  • Releases little Volatile Organic Content (VOC) upon reaction

Usage

Silway 7289 Resin should be used as supplied. It should be diluted with a organic solvent use. 
 
Depending on final requirements, Silway 7289 Resin can be used at levels ranging from 0.1 to 0.5%. Prior testing  and evaluation are required   to ensure optimum addition level for maximum water repellency and a minimum potential impact on the other board properties. 
 
Determination of optimum addition levels should be evaluated in the laboratory before any production scale evaluation.
