Product Description :Staro Polyurea is recommended for use in areas such as tank linings, water and waste water facilities, floor and deck coatings. Staro Polyurea is a 100%, fluid applied, hybrid polyurea in extended set version so as to apply the system by brush. It cures within 20 minutes to provide a tough, chemical and abrasion resistant coating.Though Staro Polyurea cures slowly in the initial stages, it reaches the optimum properties of a standard polyurea coating once the cross linking is fully achieved.

Typical Areas Of Use:
 Floor and deck coatings  Used to repair or touch up damaged polyuria coatings.  Repair systems  Joint sealants

Special Features:
 Zero VOC  Excellent adhesion  Excellent abrasion resistance  High thermal stability

Thinning : Not required – ready for use

Properties :
Mixing ratio (R:H) : 3 : 1 by weight
Type : Hybrid polyuria
Solids content by weight ASTM D 2369 : 100 %
Tensile strength ASTM D 638 : approx. 9 MPa
Elongation ASTM D 638 : approx. 670%

Chemical Resistance

Chemical spillages should always be wiped up as quickly as possible and not be allowed to concentrate up by evaporation. The data on the list of the chemicals found resistant to this product. Excellent resistance is observed against acids, alkalies and varied chemicals during our lab study is available on request.

Direction of Use:
New concrete : 28 days curing at ambient temperature is a pre requisite for any coating application. Adopt suitable surface preparation methods so as to achieve the surface profile of 150-200 microns.
Old concrete : Remove laitance and contamination by abrasive blasting. Concrete must be free of voids, bug holes, honey combs and de-laminations. Steel Surfaces : Prepare the steel surface , near white metal blasting.
Polyurea coated surfaces: If the surface is less than 3 days old, wipe with Acetone or MEK. If it is aged for more than 3 days, roughen the surface with abrasive sanding and then solvent wipe with acetone or MEK.

Application Prime the surface, Allow to cure for max 5-6 hours. If the time is lapsed for more than 24 hours, abrade the primed surface to have mechanical key. Mix the resin and hardener in 3:1 by weight. Apply by brush, roller or squeegee. Allow to cure.

Packaging: Packed in 20 kg packs and It has a shelf life of 6 months in the unopened containers.

Storage and Handling:
The product should be stored in accordance with national regulations. It should be kept in a cool, well ventilated area, away from heat, direct sunlight, sparks and children. Handle with care. Mix resin and hardener as per the recommended ratio. Use the mix solution within the pot life time.

Health and Safety Precautions
Observe reasonable care and employ ordinary hygienic principles such as washing the hands with soap and water before eating or smoking. It is recommended to wear gloves, goggles and nose masks while application. In case of splashes on the skin, dampen the cloth with thinner and wipe the hands with the cloth. Wash then with soap and water. Dried film is non toxic. Rinse with plenty of water and seek medical advice In case of contact with eyes. In case of continuous exposure to vapours, the applicator should be immediately moved to get fresh air. The disposal of excess or waste material should be carried out in accordance with the local legislations.
