K2 Bond Sbr

We are a well acknowledged firm, engaged in meeting the growing needs of the market by offering quality assured range of K2 Bond SBR. This range of coating provides superior bonding to concrete, stonework, plaster, block board, slip bricks and ceramic tiles. We source this coating from certified vendors after conducting several market surveys. To ensure safe packaging, we use quality approved drums to pack this coating. We offer this K2 Bond SBR at reasonable prices.

Features:

• Hydrolysis resistant
• Fast drying
• Longer shelf life
  

BENEFITS

User friendly simple application familiar to sit operation

• Single component liquid which improves cohesion and work ability and easily gauged as required.
• Provides waterproof of repairs, renders and toppings which are resistant to freeze/thaw cycling.
• Good tensile and flexural properties facilitate even thin applications
• Superior bonding to concrete, masonry, stonework, plaster, block board, slip bricks, ceramic tiles etc
• Free from chloride admixtures. Improves the quality of site-batched cementitious mortars and slurries
• Hydrolysis resistant and is ideal for internal and external applications with cement

PROPERTIES

Lab test results observed by assessing the mechanical properties of a 3:1 =sandzcement mortar containing K2 Bond SBR in the proportions 10 liters per 50 kg cement against a 3:1=sand:cement mortar at 28 days - air cured.

Compressive strength : 32 N/mm2

Tensile strength : 5.0 N/mm2

Flexural strength : 10.9 N/mm2

Slant shear bond : 38 N/mm2

Chemical resistance : Cementitious materials have limited chemical resistance. K2 Bond SBR added to cement mortars reduces permeability and hence minimizes the damage by aggressive chemicals, acid, gases and water.

Application Methodology

K2 Bond SBR mortars, toppings and renders must be sufficiently trowel compacted on the primed substrate layer. Exposed steel reinforcement should evenly and completely be applied with the mortar. The minimum thickness of applied K2 Bond SBR mortar should be 6 mm and up to 40 mm. Avoid sagging with higher thickness. If form work is used, it should have properly sealed faces to ensure that no water is absorbed from the repair material.

In cold conditions below 5C, the use of warm water will accelerate strength gain. Do not apply ifthe temperature is below 5C. At temperatures above 35oC, the material should be stored in the shade and cool water used for mixing. Do not expose K2 Bond SBR application to moving water and heavy rain fall.

Priming

Soak thoroughly the substrate with clean water and remove excess before application. A primer slurry should be prepared with 1 volume K2 Bond SBR to 1 volume clean water to 3 volumes fresh cement (1:1:3). To obtain a smooth consistency, the cement should be blended slowly into the premixed liquids. The primer slurry should be stirred frequently during use to offset settlement. The primer slurry should be scrubbed well into the surface of the substrate, to avoid 'ponding'. The repair mortar, topping or render must be applied on to the wet slurry primer. If theslurry primer dries before application of the mortar, it must be removed and the area reprimed.

For repairing reinforcement

Expose fully any corroded steel and remove all loose scale and corrosion deposits. Steel should be cleaned by using grit blasting process. Where chloride related corrosion is seen, the steel should be washed with high-pressured clean water immediately after grit-blasting to remove corrosion products from pits and imperfections within its surface.

Priming of Reinforcing steel

Apply one full coat of zinc rich primer to any exposed steel reinforcement and allow to dry. If required, a second application should be made and, again, allowed to dry before continuing.

Procedure for Mixing

K2 Bond SBR mortars should be thoroughly mixed in a mixer with a 400/500 rpm speed. Properly weighed quantities of cement, sand and aggregates, if required, should be dry blended for l -l .5 minutes in the mixer. Immediately, add the mixed K2 Bond SBR and clean water into the mixer. Continue mixing for 3 minutes to make homogeneous dispersal into the sand and cement. Adding further water should be minimal. Continue mixing up to a maximum of 5 minutes until a smooth consistency is achieved with the required work ability and application properties.

Packing;

K2 Bond SBR is supplied in 100 ml, 500 mL, 1,5,20 and 200 liter drums.
