Fosroc Nitobond SBR Polymer Bonding Aid
4200
incl. GST
Nitobond SBR is a modified styrene butadiene rubber emulsion which is supplied as a ready to use white liquid. It is designed to improve the qualities of site-batched cementitious mortars and slurries. Being resistant to hydrolysis, it is ideal for internal and external applications in conjunction with cement.
Uses:
- For improving and bonding concrete repair mortars, cementitious floor toppings and screeds, waterproof renders and cementitious slurries. Cementitious mortars are alkaline in nature and will protect embedded steel reinforcement. Mortars produced with Nitobond SBR may be used for horizontal, vertical and overhead repair work.
Advantages:
- Excellent bond to concrete, masonry, stonework, plaster and blockwork
- Improved tensile and flexural properties allow thin applications
- Single component liquid can be easily gauged as required
- Improves cohesion and workability
- Improves mortars to provide waterproof repairs, renders and toppings which are highly resistant to freeze/thaw cycling.
Technical Support:
- Parchem offers a comprehensive range of high performance, high quality concrete repair and construction products. In addition, Parchem offers a technical support package to specifiers, end-users and contractors, as well as on-site technical assistance.
Design Criteria:
- The application parameters for mortars modified by the use of Nitobond SBR will differ depending on the actual mix design used. Generally, however, Nitobond SBR mortars can be applied in sections up to 40 mm thickness
- in horizontal locations and up to 15 mm in vertical locations. The thickness achievable in overhead locations without the use of formwork is largely dependent on the profile of the substrate. Vertical and overhead sections greater than those stated above may be built up in layers but may sometimes be possible in a single application dependent on the actual size and configuration of the repair area, and the volume of any exposed reinforcing steel. Nitobond SBR mortars should not be applied at less than 6 mm thickness. Thicknesses up to 40 mm in a single application can be achieved by the use of formwork.
