INERTA 700 TIX
Polyurethane coating
- 2-component
- 2-component
INERTA 700 TIX is a two-component solvent-free polyurethane coating.
It is used on industrial floors where flexibility and good resistance to mechanical abrasion are required. Suitable for coating wagons that are used for transporting fertilizer, coal and ore as well as for coating concrete safety basins. INERTA 700 TIX endures impacts, hard abrasion, chemicals and constant submerging in water. It will also cure in -5°C temperature. The crack bridging ability of a 2 mm INERTA 700 TIX layer on concrete is 1.9 mm (standard EN 1062-7, method A). The coating is applied to 500 - 2000 µm thickness.
Technical data sheet
Surface preparation
Remove from the surfaces any contaminants that might be detrimental to surface preparation and application. Remove also water-soluble salts by using appropriate methods. The surfaces are prepared according to the different materials as follows:
STEEL SURFACES: Remove mill scale and rust by blast cleaning to preparation grade Sa 2½ (standard ISO 8501-1). The profile of the blast-cleaned surface must be at least coarse (reference comparator "G"). See standard ISO 8503-2 (G).
OLD PAINTED SURFACES SUITABLE FOR OVERCOATING: Any impurities that might be detrimental to the application of paint (e.g. grease and salts) are removed. The surfaces must be dry and clean. Old, painted surfaces that have exceeded the maximum overcoating time are to be roughened as well. Damaged parts are prepared in accordance with the requirements of the substrate and the maintenance coating.
CONCRETE SURFACES: The concrete must be at least 4 weeks old and well-hardened so that all moisture from casting is bound and the surface dry. The moisture of the concrete must nor exceed 97 % as relative humidity or 4% by weight (by 45 / BLY 7).
Dense laitance is to be removed from the concrete by shot-blasting, sanding or by sand blasting. Brittle and powdery top layers are treated so that the solid concrete containing aggregate is exposed. Thereafter all cement dust is removed by vacuum cleaner or brush. The concrete surface must be clean of anything that might hinder the adhesion.
The place and time of the preparation are to be chosen so that the prepared surface will not get dirty or damp before the subsequent treatment.
Additional instructive information for surface preparation can be found in standards EN ISO 12944-4 and ISO 8501-2.
Application
MIXING OF THE COMPONENTS: First the base must be mixed until homogeneous. Pour the hardener to the base container and mix thoroughly for at least 2 min. Then pour the mixture to a new container making sure that the original container is carefully scraped clean. Mix the mixture at least for an additional minute. It is recommended to use a slow-rotating drilling machine equipped with a stirrer for mixing. Inadequate stirring or incorrect mixing ratio results in imperfect curing and impaired film properties.
Take the pot life of the paint into consideration while painting.
WARNING! The amount and the temperature of the mixture will affect the pot life. The spray equipment will be damaged if the paint is let to cure inside it.
For two component application the components must be kept at a temperature of +20 - +25° C before use so that they are fluid enough for the feed pumps.
The ratio of the dosage pump must be 3:1. The heating of the Comp. A (base) shall be adjusted so that the temperature in the gun is +40 - +50°C. Comp. B (hardener) is not to be heated. The temperature of the mixture in the hose should be +30 - +40°C. The pot life of the mixture is then 5 min. If required, also the hoses must be heated.
The film thickness is controlled by a wet film gauge. Check the feed pump pressure and the consumption of the components. If work is stopped during application the mixing tube, hoses and gun are to be rinsed immediately with TEKNOSOLV 9521.
Directions given by the manufacturer of the twin-feed spray are to be followed when working.
Application conditions
The surface to be treated must be dry. During the application and drying period the temperature of the ambient air, the surface and the product shall be above +5°C and the relative air humidity below 80%. Additionally, the temperature of the surface to be treated and the product must be at least +3°C above the dew point of the ambient air. When the painted surface is touch dry, the drying temperature may be as low as -5 °C.
Storage
The storage stability is shown on the label. Store in a cool place and in tightly closed containers.
The application is done either by hot twin-feed spray with great pressure ratio, e.g. Graco Hydra-Cat, equipped with heating, (turn nozzle 0.018 - 0.026") or with a brush or roller.
