Too much solvent results in lower sag resistance and slower cure. Note * The temperature of the mixture of base and curing agent is recommended to be at least 15☌, otherwise extra solvent may be required to obtain correct viscosity. Nozzle tip 0.58-0.79 mm (0.023-0.031") Spray angle 40-80°įilter Check to ensure that filters are clean. Pressure at nozzle 15 MPa (150 kp/cm², 2100 psi). A (base) to be mixed thoroughly with 1 part Jotamastic 87, WG Comp. A (base) to be mixed thoroughly with 1 part Jotamastic 87, Std Comp. Application data Mixing ratio (volume) Std Comp. Roller May be used for small areas but not recommended for first primer coat, however when using roller application care must be taken to apply sufficient material in order to achieve the specified dry film thickness. Application methods Spray Use airless spray Brush Recommended for stripe coating and small areas, care must be taken to achieve the specified dry film thickness. Before painting the surface shall not be glossy with moisture, but can have a patchy appearance. The surrounding air must have a relative humidity not exceeding 85 Hydrojetting of steel surface makes a wet surface. Good ventilation is required in confined areas to ensure proper drying. The temperature of the substrate should be minimum +10☌ (Std) (-5☌ in WG) and at least 3☌ above the dew point of the air, temperature and relative humidity measured in the vicinity of the substrate. Please contact your local Jotun office for more information. The coating may be used on other substrates. For maintenance UHPWJ to WJ2 (NACE No.5/SSPC-SP 12) or Power tool cleaning to min. Contact your local Jotun office for more information. Coated surfacesĬlean, dry and undamaged compatible primer. Shopprimed steelĬlean, dry and undamaged approved shopprimer. In case of waterjetting the flash rust degree shall not exceed M (moderate) in SSPC and NACE standards for waterjetted surfaces. Improved surface treatment (blast cleaning to Sa 2½) will improve the performance. Bare steelĬleanliness: Power tool cleaning to min. The surface should be assessed and treated in accordance with ISO 8504. Surface preparationĪll surfaces should be clean and free from contamination.

MSC 82/W), see the "Application procedure for water ballast tanks - Jotamastic 87".ĪPAS approved to specification 0156/2, 2973, 2973F, 29. If exposed to sunlight chalking may occur.įor application in water ballast tanks at newbuilding stage in accordance with PSPC (IMO Res. Gives excellent corrosion protection both in salt and fresh water. Can be used alone or in combination with various systems of primers and topcoats. Steel where blast cleaning may not be possible and on hydrojetted surfaces still being moist where gloss and colour retention is of minor importance. This product is a part of a complete system which is certified not to spread flames. Available with different hardeners for varying substrate temperatures, Standard (Std) and Wintergrade (WG). Jotamastic 87 is a two-pack surface tolerant, abrasion resistant, high solids, polyamine cured epoxy mastic coating which may be applied in high film thickness.
