SILRES® WH is a water thinnable, solventless emulsion of a functional silicone resin.


Properties

Dilute solutions of SILRES® WH serve as high-quality water repellents for impregnating wood surfaces. Undiluted SILRES® WH may also serve as high-quality hydrophobizing additive for aqueous wood coatings/wood stains.

  • water based
  • development of longlasting beading effect on wood
  • significant reduction of capillary water absorption of wood, particularly after weathering
  • no protection against degradation of lignin by UV radiation and accompanying graying (UV transparent)
  • increases the durability and longevity of wood stains/coatings for wood because of excellent hydrophobizing properties
  • helps to minimize all harmful effects caused by water uptake


For the use as hydrophobic impregnant for wood SILRES® WH has to be diluted with water. We recommend a solid content of 5-10% (dilute the product in the ratio 1:4 to 1:9), the exact figure depending on how absorbent the substrate is. The application on wood is done by brushing, spraying or flooding. SILRES® WH is used in undiluted form as hydrophobizing additive for aqueous wood stains/ wood coatings during or after their production. Wood stains/ wood coatings modified with SILRES® WH are characterized by excellent water repellency and outstanding water resistance, especially after weathering. The addition of 1 wt.% to 3 wt.% is recommended.

 

Storage

The product or dilutions thereof should be stirred well before use. The 'Best use before end' date of each batch is shown on the product label.
