CONCRETE RUBBER – LITE
SEA STAR CONCRETE RUBBER-LITE is a ready for use aqueous dispersion of a Styrene-Butyl Rubber with low solid contents. It contains an anionic/nonionic emulsifier system and is free from film forming aids, solvents, plasticizers and ammonia.

SEA STAR CONCRETE RUBBER-LITE is used in combination with cement, lime gypsum, etc. Addition of SEA STAR CONCRETE RUBBER-LITE improves workability, wet adhesion and plasticity of fresh mortars. The dispersion has a strongly liquefying effect and reduces the water requirement at the same mortar consistency. SEA STAR CONCRETE RUBBER-LITE improves following end properties, flexural strength (up to 30 %), adhesive strength, abrasion / water / chemical / freeze / thaw resistance and shrink /swell behavior. SEA STAR CONCRETE RUBBER-LITE has extremely good resistance to saponification, by which long term stability in the strongly alkaline region even under moist conditions is secured.
The dispersion has no corrosion promoting action on steel reinforcements and is film forming above + 3 °C. Additions of film forming agents or plasticizers are therefore not required. SEA STAR CONCRETE RUBBER-LITE is used in floor, screeds, leveling compounds, adhesive – bonded joints, sealers / primers, repair mortars for concrete restoration, cement – based anti-corrosion paints, gypsum –based stoppers / fillers, and building adhesives. Owing to the limited UV-stability of styrene – butyl copolymers surface chalking can occur. This behavior is identical with unmodified mortars. Addition of 10 – 50 % by weight of SEA STAR CONCRETE RUBBER-LITE related to the cement content is recommended for the improvement of mortars.
SEA STAR CONCRETE RUBBER-LITE is preserved against bacterial and fungal attack. In the manufacture of finished products, the material has to be retreated, as usual, with suitable biocides to give enhanced preservation.
On available data SEA STAR CONCRETE RUBBER-LITE has no hazard classification according to 88/379 EEC. The surfactants and to a lesser extent the free monomer present in polymer dispersions can cause dermatitis through repeated contact in sensitive individuals. Eye contact may cause irritation.

SEA STAR CONCRETE RUBBER-LITE has to be stored protected from frost and, as far as possible, below 40°C. Storage at temperatures between + 5 and + 30 °C is recommendable. SEA STAR CONCRETE RUBBER-LITE contains a preservative to counter microbial attack during transportation. Care must be taken to ensure that storage containers are tightly closed. When stored correctly SEA STAR CONCRETE RUBBER-LITE has a storage life of 12 months from date of delivery.
This product contains Portland cement which is slightly alkaline when wet. For people with sensitive skin, continuous use may cause irritation. Gloves or a suitable barrier cream should be used. As a general Code of safety practice all chemical products should be treated with care, kept away from children and animals, especially protect eyes and skin. In emergency seek medical advice.
