Penguard HSP

Product description

Penguard HSP is a fast drying, high solids two-pack epoxy coating.

Recommended use

As an anti corrosive primer and/or intermediate coating for protection of steel and other substrates in urban and industrial atmospheres, coastal areas with low/moderate salinity and where fast dry-to-recoat and/or dry-to-handle times are desired. Lower film thickness may require thinning.

Note that primers used as the final coat may fade and chalk in time when exposed to sunlight and weathering effects. Colour may vary from batch to batch. If exact match to colour standards and long term cosmetic performance is needed please see our range of topcoats and finishes.

Hong Kong rules:

Category of paints - Other vessel coatings; VOC 254 gms/ltr HK EPD method (Ready to use); Exempt compound - N/A; Specific gravity: 1.59 (A+B); Both VOC and Specific gravity values provided are typical values, subject to changes when different colour involved.

Surface preparation

All surfaces should be clean, dry and free from contamination. The surface should be assessed and treated in accordance with ISO 8504.

Bare steel

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)

Shopprimed steel

Clean, dry and undamaged approved shopprimer.

Coated surfaces

Clean, dry and undamaged compatible primer. Please contact your local Jotun office for more information.

Other surfaces

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 0°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.

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.

Application data

Mixing ratio (volume) 4:1

Mixing 4 parts Comp. A (base) to be mixed thoroughly with 1 part Penguard HSP, Comp.

B (curing agent) for 10 min prior to use.

Pot life (23°C) 2 hours. (Reduced at higher temp.)

Thinner/Cleaner Jotun Thinner No. 17

Guiding data airless spray

Pressure at nozzle 15 MPa (150 kp/cm², 2100 psi)

Nozzle tip 0.38 - 0.58 mm (0.015 - 0.023")

Spray angle 40 - 80°

Filter Check to ensure that filters are clean.

Drying time

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

Substrate temperature






Surface dry


5 h



0,5 h

Dry to recoat, minimum Dry to recoat, maximum 1





1 h

1. Provided the surface is free from chalking and other contamination prior to application, there is normally no overcoating time limit. Best intercoat adhesion occurs, however, when the subsequent coat is applied before preceding coat has cured. 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.
