SILRES® BS 1601

1 of 110 products in this brand
SILRES® BS 1601 is n-octyltriethoxysilane, which is used undiluted as a water-repellent primer and impregnating agent for normal and reinforced concrete. It offers significant benefits such as the reduction of chloride and water absorption by the concrete, minimizing concrete loss due to freeze/road salt attack, and exhibiting low volatility. Once applied to the concrete, SILRES® BS 1601 reacts with atmospheric moisture or pore water present in the concrete, resulting in the generation of the active ingredient. This active ingredient effectively reduces the water absorbency of the treated concrete while maintaining a high level of water vapor permeability. Importantly, the treatment does not block pores or capillaries within the concrete.

Application Details
  • Liberally apply two coats (wet-on-wet) of the impregnating agent uniformly to the concrete. Two coats are needed to ensure that all of the surface is covered. Do not allow puddles to form. Apply with a low-pressure pump, allowing impregnating agent to flood over the surface. For even distribution use a roller afterwards.
  • Allow fresh concrete at least two weeks preferably four to set before impregnating it, to ensure that the cement sets properly.  
  • Remove coarse particles and dust from new, unsoiled surfaces with a brush or compressed air. Use superheated steam to clean weathered surfaces that are heavily soiled with oil, abraded rubber etc, prior to treatment.
  • Only impregnate concrete that has a uniformly dry surface with no damp patches. An equilibrium in humidity with the outside air is reached, when a freshly produced surface of fracture is not turning lighter in appearance (due to drying). No darkening of concrete or condensation may occur over night underneath a PE film (500 mm x 500 mm) attached to the concrete at its edges.
  • Should it suddenly start to rain, stop treatment and cover the impregnated areas. SILRES® BS 1601 should not get into direct contact with bitumen. The resistance of thermal insulating materials against product has to be determined.
  • SILRES® BS 1601 is recommended as a water-repellent impregnating agent and primer for normal and reinforced concrete for bridges, roads and buildings.

Properties

Physical Form
Properties

Greatly reduction of chloride and water absorption by concrete - reduces loss of concrete due to freeze/road salt attack - low volatility After application to the concrete, SILRES® BS 1601 reacts with the atmospheric moisture or pore water in the concrete, thereby generating the active ingredient. The active ingredient greatly lowers the water absorbency of the treated concrete, which nevertheless retains a very high degree of water vapor permeability since neither pores nor capillaries are clogged.
