Description - Perma latex sbr is based on styrene butadiene rubber, special adhesive and bonding chemicals along with hydrophilic agents. Perma latex sbr gives a versatile performance in many civil engineering applications. The product is a milky white liquid.
Primary usesPerma latex sbr is a high quality emulsion which enhances the performance of cement mortar and concrete, some examples from its innumerable uses are as follows:An excellent product in concrete repairs as in combination with cement (1:1) it produces a very strong primer and as an additive in the mortar to make a strong waterproof plaster.An indispensable product in floor repairs. Perma latex sbr is used in mortar as an additive to make screeds which can be feather edged and can be used successfully in restoring the nosings of floor ducts and stairs.In case of multilayered plaster perma latex sbr bonding slurry helps in building up layer after layer. The bond coat not only serves as a bonding agent but also as a waterproof barrier.Perma latex sbr modified mortars are used in joining prefabricated members and as bedding mortar in precast block work to secure water tight joints.In terrace waterproofing and patch up repairs perma latex sbr forms an important member as it helps bonding new plaster to old plaster and also helps in making non shrink crack free mortar for repairs.With fine sand cement mortar perma latex sbr is admixed to get an excellent adhesive for fixing wall panelling, stones, tiles including granite and marble tiles.Cement perma latex sbr slurries are used ascorrosion inhibitor on exposed reinforcements and on bridge girders to protect them from attack of chlorides and sulphates.Perma latex sbr is used in making waterproof slurries for repairs of old waterproofing works and waterproof mortars for new waterproofing works.Perma latex sbr is used in arresting leakages from water retaining structures whether through pipe, concrete junctions or from masonry pointings.Perma latex sbr is used in arresting leakages from overhead and underground potable water tanks.Perma latex sbr can be used at a dosage of 3 ltr per 50 kg bag of cement to make polymer modified mortar for bridge repair work and general repairs.AdvantagesPerma latex sbr is a very strong bonding agent for mortars and concrete to bond with old concret, stone, steel, brick etc.Perma latex sbr is a strong corrosion inhibitor. It prevents entry of chloride and sulphate ions into the cementitious structure.Perma latex sbr is a superior waterproofing product.Perma latex sbr is an excellent adhesive for tiles, stones, marble and granite tiles.It is very easy to use and is non toxic. Perma latex sbr poses no environmental hazards.Perma latex sbr increases the compressive, tensile and flexural strength of concrete and mortars.Perma latex sbr makes mortars non shrink, strong and dust proof.Where no remedy exists for saltpetre action on walls, perma latex sbr modified mortar solves the problem with ease.Perma latex sbr is successfully used as a primer to brick bat coba systems on terraces.Perma latex sbr is economical than many similar products yet gives multifold advantages.Directions for useSurface preparation: surfaces to receive any repair treatment should be sound, free from loose particles, grease, oil or any deleterious material. All loose portions should be cut back to sound concrete. Surface should be sufficiently wetted to saturation level but should be free from stagnant water.Aggregates: aggregates should be clean and sound. They should be designed properly with respect to the mix as well as maximum aggregate size with respect to the thickness of concrete or mortar to be laid. In case of mortars maximum grain size of the fine aggregate should be around one fourth the thickness of the member to be cast and it should be graded.
