Penguard HB is a high build, two-pack epoxy coating based on epoxy resin with high molecular weight. This product is a part of a complete system which is certified not to spread surface flames.
As an anti corrosive primer and intermediate coating for corrosion protection of various substrates including steel. May be used in tanks for potable water. A suitable washing procedure depending on national rules may be required.

All surfaces should be clean, dry and free from contamination. The surface should be assessed and treated in accordance with ISO 8504.
Cleanliness: Blast cleaning to Sa 2½ (ISO 8501-1:2007). Roughness: using abrasives suitable to achieve grade Fine to Medium G (30-85 µm, Ry5) (ISO 8503-2)
Clean, dry and undamaged approved shopprimer.
Clean, dry and undamaged compatible primer. Contact your local Jotun office for more information.
For aluminium and galvanized surface; degreasing, light abrading or sand sweeping.
The coating may be used on other substrates. Please contact your local Jotun office for more information.
Condition during application
The temperature of the substrate should be minimum 10°C and at least 3°C above the dew point of the air, temperature and relative humidity measured in the vicinity of the substrate. Good ventilation is usually required in confined areas to ensure proper drying. The coating should not be exposed to oil, chemicals or mechanical stress until cured. If necessary, Penguard Stayer, Penguard Primer, Penguard HB, Penguard Special may be used down to 2ºC, provided a special accelerator is added.
Use airless spray
Recommended for stripe coating and small areas, care must be taken to achieve the specified dry film thickness.
Mixing ratio (volume)
4 parts Comp. A (base) to be mixed thoroughly with 1 part Penguard, Comp. B (curing agent).

Check to ensure that filters are clean.
Drying times are generally related to air circulation, temperature, film thickness and number of coats, and will be affected correspondingly. The figures given in the table are typical with:
* Good ventilation (Outdoor exposure or free circulation of air)
* Typical film thickness
* One coat on top of inert substrate
Dry to recoat, minimum
Dry to recoat, maximum
Provided the surface is free from chalking and other contamination prior to application, there is normally no overcoating time limit. 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.
The given data must be considered as guidelines only. The actual drying time/times before recoating may be shorter or longer, depending on film thickness, ventilation, humidity, underlying paint system, requirement for early handling and mechanical strength etc. A complete system can be described on a system sheet, where all parameters and special conditions could be included.

Other systems may be specified, depending on area of use
SPECIAL WASHING PROCEDURE WHEN THIS PRODUCT IS USED IN TANKS FOR POTABLE WATER
After the paint is cured (see drying/curing time above), the tank is filled with warm water (above 60 - 80°C), which shall remain in the tank for 24 hours. Then the tank is thoroughly washed, using water of min. 80°C together with brushes or washed with steam
After the paint is cured (see drying/curing time above), the tank shall be ventilated with warm air, min 23°C for 7 days. Then the tank is filled three times with warm water (min. 50°C), each filling shall remain in the tank for 24 hours. Finally, the tank is washed, using water of min. 50°C together with brushes or washed with steam
Other washing procedures may be acceptable, please contact your local Jotun representative for details.
The product must be stored in accordance with national regulations. Storage conditions are to keep the containers in a dry, cool, well ventilated space and away from source of heat and ignition. Containers must be kept tightly closed.
Handle with care. Stir well before use.
