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.

APPLICATION ADVICE
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.

HAZARDS IDENTIFICATION
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.
