Protectasilane 100

Tech-Dry® Protectasilane 100 is is a repellent containing 100% octyltriethoxysilane. This sealer is used as a water repellent impregnant for concrete protection and penetrates deeply into the capillaries in the concrete to create a first class water repellency.

Protectasilane 100 is typically designed as a high value water repellent sealer for critical structural concrete elements in water exposed situations. It provides excellent concrete protection from weather exposed situations and wind driven rainwater.

USE:
Tech-Dry® Protectasilane 100 can be applied using brush, roller or spray. However, for the best concrete protection, the product is preferably applied by saturation flooding using a hand pressure spray or airless spray equipment. A second application should follow immediately after the first coat is absorbed by the surface. This is termed a “wet-in-wet” application. The object is to saturate the surface to allow better concrete protection and penetration.

FEATURES:

  • 100% active with no hydrocarbon solvent used
  • Ability to deeply penetrate into dense concrete
  • Permanently bonds to the concrete with no peel or blister
  • Forms UV, alkali stable and durable siloxane structure within concrete matrix
  • Reduces water penetration, efflorescence and the ingress of harmful salts such as chloride ions
  • Does not significantly change the surface appearance and vapour permeability
