Product Description
Fosroc Nitobond SBR Latex Bonding Agent is modifi ed styrene butadiene emulsion specially designed for use as a bonding aid and gauging liquid for cementitious systems. It is resistant to hydrolysis and can therefore be used for external applications too.

Main Uses:

• Modifying and improving bonding of floor toppings, renderings and mortars.
• Repair of worn, damaged and spalled concrete.
• Repair of large cracks.
• Polymer modified floor screeds.
• Waterproof plasters for masonry and slurries.
• For modifying and improving bonding of fl oor toppings, renderings and mortars; repair of worn, damaged and spalled concrete, repair of large cracks; polymer modifi ed fl oor screeds; waterproof plasters for masonary and slurries. 

Advantages

• Simple to use - Single component, gauged as required.
• High - Provides excellent bond to concrete, adhesion plaster, masonry, stone work, etc.
• Improves -Gives weather resistant mortar with improved durability impermeability to chlorides and other harmful agents.
• Reduces - Provides waterproof screeds, plasters and Permeability slurries.
• Increases - Improved tensile and flexural properties strength allow thin applications.
• Versatile - Compatible with all common hydraulic cements.

Technical Support

• Fosroc provides a technical advisory service supported by a team of specialists in the field.

Chemical Resistance:

• Cementitious materials have limited chemical resitance. The addition of Nitobond SBR (Latex) to cement mortars reduces permeability and therefore helps reduce the rate of attack by aggressive chemicals.

Surface Preparation

• The object of the surface preparation is to achieve a clean sound surface with a good mechanical key. All substrates should be cleaned and free of dust, plaster, oil, paint, grease, corrosion deposits, and any other deleterious substances.
• Laitence should be removed by mechanical means. Smooth substrates must be mechanically roughened e.g. by scabbling, needle gun or grit blasting to provide an adequate key.
• Corroded reinforcing steel should be exposed around its full circumference and cleaned to remove all loose scale and corrosion deposits. It is always preferably to clean the steel to a bright condition. Use of emery cloth, grit or sand blasting is recommended.

Priming

• Reinforcing steel must be primed with Nitozinc Primer immediately after cleaning. The concrete substrate should be thoroughly dampened with water and any excess removed before being primed by thoroughly scrubbing in a slurry coat of 1 volume  Nitbond SBR (Latex) to 1 volume water to 3 volumes fresh cement.
• In order to obtain a smooth consistency the cement should be  blended slowly into the liquids. Stir frequently during use to off set settlement.
• Avoid ‘puddling’ of the slurry coat. The topping must be applied on to the wet slurry. If the slurry dries out it must be removed and the clean substrate reprimed

Additional Guidance:

• Prepare surfaces thoroughly. Toe-in at edges wherever possible to avoid feather edging. All surfaces including edges must be primed. All applications should be wet on wet, the primer must not be allowed to dry.
• The level of added water in the mix designs may need adjusting to achieve the required consistency. In general water content should be kept to the minimum necessary.
• For consistent performance the use of clean, dry sand is recommended. Where wet sand is used, reduce the added water level as appropriate.
• Health & Safety instructions Nitobond SBR (Latex) should not come in contact with skin and eyes or be swallowed.

Product DescriptionAsian Paints Smartcare Acrylic Bonding Chemical Asian Paints SmartCare Acrylic Bonding Agent is a single component white emulsion which is based on modified acrylic co-polymers. It is formulated to be used as a bonding agent for cementitious mortars, micro-concretes and cement plasters.

Sunanda Hack Aid Plast is a high-performance, ready-to-use bonding agent designed to enhance the adhesion of plasters like gypsum, POP, or anhydrous plasters to various concrete surfaces. It replaces the traditional surface hacking process with a more efficient chemical bonding technique.

Sunanda Polyalk EP is a polymeric formulation designed to enhance and modify the microstructure of cement-based materials. It creates a polymeric spatial network within the voids of the cement, significantly improving its properties. This product is commonly used for applications such as repairing reinforced concrete (RCC) structures, industrial floors, water tanks, heritage restoration, grouting, and plastering. It's also suitable for retrofitting stairs and repairing pipe joints.

Asian Paints SmartCare Multi-purpose Polymer is a high performance acrylic emulsion based binder that enables fixing of natural stones and heavy tile cladding on vertical surfaces in interiors as well as exteriors by substantially improving the adhesion of SmartCare Tile Adhesives.

Nitobond EP10 is a two-component, epoxy-based bonding agent designed for use in construction and repair applications. It is widely used to enhance the adhesion between new concrete and old concrete surfaces or between concrete and other substrates.
