MasterEmaco SBR 2 is a milky-white, Styrene-Butadiene co-polymer latex liquid, produced from styrene and butadiene by high pressure emulsion polymerization with high dispersive properties. When used with cement, concrete and plaster, it reduces the mixing time through high dispersion of the polymer and improves waterproofing, new to old concrete/plaster bonding and strength characteristics and reduces shrinkage and cracking of the mix.

Recommended Uses:

• Concrete repair: Spalled concrete, repairing floors, beams and pre-cast slabs, chajjas etc.
• Bond Coat: For bonding new concrete to old concrete, plaster, stone/brick masonry.
• Plaster repair: For repairing plaster or making water proof plaster which is better than normal plaster.
• Floor screeds and toppings: Abrasion resistant and non-dusting floors.
• Waterproofing: Basements side walls and rafts, lift pits, inspection pits, sunken/overhead water tank, sunken portions of bathrooms and toilets, balconies, chajjas, exposed roofs before finished screed.
• Other typical applications: Bedding tiles, fixing or re-fixing slip bricks.

• Multiple applications: Robust product that is economical, easy to handle and store.
• Easy to Mix: Faster mixing to enhance worker efficiency.
• Shrinkage/crack control: High flexural / tensile strength to control cracking.
• Mortar modifier- Improved flexibility, no bleeding, lower water cement ratio and high resistance to water penetration.
• Improves physical/mechanical properties – higher abrasion resistance, good adhesion to building materials similar thermal characteristics to concrete.
• Corrosion control: Prevents corrosion of embedded steel.

• High Dispersion technology: Allows for better workability at slightly reduced water

MasterSeal 910- Water swelling waterbar for joints
How does MasterSeal 910AP work?
When in contact with water the MasterSeal 910AP Waterbars will slowly increase in volume (swell) without changing the homogeneous structure of the polymer matrix. The increase in volume by the swelling action can be up to 200% (depending on type of water). The pressure of the swelling action will cause the MasterSeal 910 Waterbar to profile itself exactly into the joint filling all cavities and effectively stopping water seepage, even at high external water pressure.
The MasterSeal 910 Waterbars will not transport water through their polymer matrix and thus not act as a capillary duct. The swelling action is limited to the sides exposed to water.
Recommended uses:
MasterSeal 910 Waterbar is suitable for all construction joints subject to hydrostatic pressure, on one or both sides. MasterSeal910 provide simple but efficient waterproofing of construction joints.
What makes MasterSeal 910 a unique solution?
MasterSeal 910 is a hydro-swelling waterbar, ready for installation in construction joints to render the joints leak proof. It is based on specially designed polymer composite that acts by undergoing reversible swelling on exposure to water to form an effective seal.
What are the features and benefits of MasterSeal 910?
MasterSeal 910 is based on a newly developed polymer technology providing flexible polymer composites which have high chemical resistance capable of storing water in their molecular structure by increasing their volume.
MasterSeal 910 provides simple but efficient waterproofing of construction joints. Movements in the joint, e.g. by shrinkage or settlement in the substrate, are taken up by the elastic profile of the MasterSeal 910 Waterbar. MasterSeal 910 has been successfully employed to waterproof joints where an opening of up to 5mm was deliberately created. Water pressure of up to 5 bar was sealed.
