Application:
Surface Preparation:
For New Concrete Surface : Ensure that the concrete surface is cured for minimum 3 months. Preferably the surface has to be prepared by light blasting. In case, blasting is not practical, wire brushing/ power tool cleaning has to be adopted to remove laitance and other loose.
particles, followed by etching the surface to get a good profile by treating white dilute (10%) Hydrochloric Acid. Remove acid and contaminants by liberal wash with Fresh water. Ensure that acid solution does not retain and penetrate through the joints of the concrete surface. Allow the surface to dry thoroughly before applying primer.

For Old Concrete Surface: Remove the surface contaminants like grease, oil etc., by solvent wiping or by 10% caustic solution. Preferably the surface has to be prepared by light blasting. In case, blasting is not practical, wire brushing/ power tool cleaning has to be adopted to remove laitance and other loose particles, followed by etching the surface to get a good profile by treating white dilute (10%) Hydrochloric Acid. Remove acid and contaminants by liberal wash with fresh water. Ensure that acid solution does not retain and penetrate through the joints of the concrete surface. Allow the surface to dry thoroughly before applying primer. For Metal Surface : New hot-rolled steel: blast cleaned to min Sa 2.5 of Swedish specification.

MIXING Stir the base and hardener separately. If settling is observed in the base or hardener, loosen the settled material with the help of hand stirrer followed by power driven stirrer for quick homogenous mixing. Mix hardener gradually into the base under continuous stirring as follows: Mixing Ratio Base : Hardener 15 minutes (by volume) 2 : 1 Pot life at 30 C 45 minutes

Note:
1 Concrete surface should be thoroughly dry before application of primer and has a major influence on the performance.
2. Staroxy 102 ARSF primer with moisture and oil tolerant is recommended for priming the surface before applying of Stanrose SLR 150-2000
3. Stanrose SLR 150-2000 Epoxy coating/Flooring is recommended in the radioactive area with a varied DFT of 250 to 2000 microne thickness as per the requirements.

Advantages:
● High performance coating for protection of steel in aggressive conditions.
● Self priming, can be applied directly on steel and concrete.
● Good flexibility and elongation.
●Good corrosion and chemical resistance
●Low volatile organic component.

Storage & Packing:
Storage Store in a cool, dry place. Store in accordance with local regulations.

Health 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 vapour, 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
