Polyurethane Paints

Additional Details

We offer polyurethane paints including polyurethane aliphatic finish. These are available in a two pack aliphatic acrylic polyurethane high gloss top coat with excellent weathering resistance and color retention properties. Due to its toughness and chemical resistance properties, it finds extensive use in coastal and chemical environment. Our paints are widely used in fertilizer plants, oil refineries, petrochemical units, marine installations, chemical plants, transportation industries, power plants, rail coach & chemical wagon exteriors and offshore structures.

 Following are the preparation for various surfaces:

STEEL SURFACES:

Surface should be perfectly clean and dry before application of appropriate primer. Degrease and blast clean to Sa 2½ grade minimum of Swedish specification SIS - 05 - 5900 - 1967. If blast cleaning is not practical make full use of mechanical tools along with manual cleaning and wire brushing to remove loose rust/scale to St 2 or St 3 grade of Swedish Specification.

CONCRETE SURFACES:

For new concrete surface: Make sure that the surface is cured for minimum 2 months. Remove laitence, loose surface powder by light sand blasting. If blast cleaning is not feasible, roughen the surface by acid etching with 10% Hydrochloric Acid solution followed by thorough freshwater hosing to remove any residual acid. The surface should be perfectly dry and clean before application of appropriate primer.

For old concrete surface: Remove grease, oil etc by solvent wiping. Remove water-soluble contaminants by fresh water hosing. Roughen the surface by acid etching, if light sand blasting is not feasible. The surface should be perfectly dry and clean before application of appropriate primer.
