Carboxylated Styrene Butadiene Resin

Obaproof SBR Latex 188 is a superior quality waterproofing copolymer latex with a blend of special auxiliary chemicals. It is a water base dispersion of synthetic polymer which will substantially improve the workability of concrete and mortars used for repairs, floor toppings and renders in building and construction industry. By carefully selecting the proportions of cement, sand water and Obaproof SBR Latex 188, it will be ideal for bonding of tiles as well as natural stone, marble, granite, slate and ceramic tiles onto concrete, plaster, concrete block, fibre cement sheet, particle board, old ceramic tiles etc.

Advantages:
• Ready to use from container- Simply add to the mixture of cement.
• Improve adhesion markedly to a wide range of substrates.
• Excellent resistance to water and water vapour when dry.
• Allows thin selection application and feather edging.
• Reduces shrinkage.
• Improves abrasion, chemical and impact resistance.
• Increases compression, flexural and tensile strength.
• Reduces water permeability, protects against carbonation.
• Reduced water cement ratio for equivalent workability.

Application:
• Elooring system: From underlayment to the tough industrial screeds.• Concrete Repair: General repair of old building, patch repair, floors,reinforced concrete, etc.
• Primer/Bond Coats & Protective Coatings: Enhance protection of structure against salts, carbonation, mild acid, etc.
• Waterproofing: General waterproofing of floors, walls, bund walls, and tanking applications.
• Mortar/Renders: Improve adhesion, crack resistance and weather resistances.
Grout: Increase bond, chemical resistance and crack resistance.
 Tile adhesives: To provide a high safety factor against failure, even in permanently wet conditions.

Preparation:
1. Surface must be clean, dry and free of dirt, grease, oil or water.
2. Best results are obtained when smooth substrates are mechanically roughened or grit blasted or needle scrabbled to provide adequate key
for installation of Obaproof SBR Latex 188 for cementitious mixes.
