The given data must be considered as guidelines only. If the coating has been exposed to direct sunlight for some time, special attention must be paid to surface cleaning and mattening/removal of the surface layer in order to obtain good adhesion. Best intercoat adhesion occurs, however, when the subsequent coat is applied before preceding coat has cured. Provided the surface is free from chalking and other contamination prior to application, there is normally no overcoating time limit. Good ventilation (Outdoor exposure or free circulation of air)ġ. The figures given in the table are typical with: Drying timeĭrying times are generally related to air circulation, temperature, film thickness and number of coats, and will be affected correspondingly. Nozzle tip 0.46 - 0.69 mm (0.018-0.027") Spray angle 40 - 80°įilter Check to ensure that filters are clean. Pressure at nozzle 15 MPa (150 kp/cm², 2100 psi) B (curing agent) for 10 min prior to use. A (base) to be mixed thoroughly with 1 part Penguard Express, Comp. Application data Mixing ratio (volume) 4:1 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. The coating should not be exposed to oil, chemicals or mechanical stress until cured. Good ventilation is required in confined areas to ensure proper drying. The temperature of the substrate should be minimum -5☌ 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. Coated surfacesĬlean, dry and undamaged compatible primer. Roughness: using abrasives suitable to achieve grade Fine to Medium G (30-85 µm, Ry5) (ISO 8503-2) Shopprimed steelĬlean, dry and undamaged approved shopprimer. Bare steelĬleanliness: Blast cleaning to Sa 2½ (ISO 8501-1:2007). The surface should be assessed and treated in accordance with ISO 8504. Surface preparationĪll surfaces should be clean, dry and free from contamination. Hong Kong rules: Category of paints - Other vessel coatings VOC 260 gms/ltr HK EPD method (Ready to use) Exempt compound - N/A Specific gravity: 1.51 kg/ltr (A+B) Both VOC and Specific gravity values provided are typical values, and will vary according to colour chosen. If exact match to colour standards and long term cosmetic performance is needed please see our range of topcoats and finishes. Note that primers used as the final coat may fade and chalk in time when exposed to sunlight and weathering effects.

Can be used alone or in various systems of primers and topcoats. Recommended useĪs an anti corrosive primer and/or intermediate coating for corrosion protection of steel and other substrates in athmospheric exposure where fast dry-to-recoat and/or dry-to-handle times are desired. Penguard Express is a fast drying, high solids two-pack epoxy coating which may be applied in high film thickness and at lower temperatures.
