Permeable Waterproofing Agent

Product Name: Permeable Waterproofing Agent

Item No: SilibaseWR-0818

Introduction:

SilibaseWR-0818 Permeable Waterproofing Agent is aqueous solvent free, creamy, silane-based water repellent. It is a high-quality specialty product for impregnating both normal and reinforced concrete. 

SilibaseWR-0818 Permeable Waterproofing Agent is a small molecule to allow for deep penetration into the construction materials (especially concrete and reinforced concrete) surface. This material reacts with moisture in the air and in the substrate in the presence of an alkaline or

acidic environment to produce hydroxyl groups. These hydroxy groups will bond with the substrate and itself to produce a hydrophobic treatment that inhibits water absorption into the substrate. An alkaline environment, such as new concrete, will catalyze the reaction and speed the formation of the hydrophobic surface.

Chemical Name: iso-Octyltriethoxysilane Cream

Typical Physical Properties:

Color and Appearance: White paste

Density (25/25℃): 0.90

Active content: 80.0%  

Application:

SilibaseWR-0818 Permeable Waterproofing Agent is recommended particularly for impregnating and priming concrete and reinforced concrete used in building bridges, roads and buildings. 

In principle, SilibaseWR-0818 Permeable Waterproofing Agent may be used on any alkaline substrate that has been treated previously with concentrated or undiluted impregnating agents, such as alkoxy silanes. 

Methods of application include airless sprayer, roller and brush. When a brush or roller is used, repeated applications should be made until the surface remains moist for a few minutes. If an airless sprayer is used, application should continue until the substrate is thoroughly saturated.  

A test application is necessary on each surface to be treated to ensure compatibility and the desired water repellent result. Up to 400g/m² may be applied in one operation to vertical surfaces and roofs, without loss off material. The exact amount depends on the absorbency of the substrate. At higher application rates, the impregnating agent might liquefy at the top of the concrete and it might start to run off. A second coat of SilibaseWR-0818 Permeable Waterproofing Agent may be applied at any time but is usually unnecessary. 

Surfaces should be free of standing water, surface dirt, dust, oils, and other contaminants. To ensure that the cement sets properly, it is best to wait at least two weeks, and preferably four, before impregnating it. 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 or abraded rubber, etc., prior to treatment. 

SilibaseWR-0818 Permeable Waterproofing Agent should not get into direct contact with bitumen.  

Packing and Storage:

SilibaseWR-0818 Permeable Waterproofing Agent is supplied in 180Kg steel drum.  

In the unopened original container SilibaseWR-0818 Permeable Waterproofing Agent has a shelf life of one year in a dry and cool place.
