Use
For application to a wide variety of substrates including hand prepared rusty steel, abrasive blast cleaned and
hydroblasted steel, and a wide range of intact, aged coatings.
Provides excellent anti-corrosive protection in industrial, coastal structures, pulp and paper plants, bridges and
offshore environments in both atmospheric exposure and immersion service.

Certified to
ANSI/NSF Standard
61. NSF Certification
is for tanks greater
than 100 gallons
(378.5 liters).

Surface preparation
The performance of this product will depend upon the degree of surface preparation. The surface to be coated
should be clean, dry and free from contamination. Prior to paint application all surfaces should be assessed
and treated in accordance with ISO 8504:2000.

Accumulated dirt and soluble salts must be removed. Dry bristle brushing will normally be adequate for
accumulated dirt. Soluble salts should be removed by fresh water washing.

Abrasive Blast Cleaning
For immersion service, Interseal 670HS must be applied to surfaces blast cleaned to SSPC-SP10 or Sa2.5
(ISO 8501-1:1988). However, for atmospheric exposure best performance will be achieved when Interseal
670HS is applied to surfaces prepared to a minimum of SSPC-SP6 or Sa2.5 (ISO 8501-1:1988).
Surface defects revealed by the blast cleaning process, should be ground, filled, or treated in the appropriate
manner. A surface profile of 2-3 mils (50-75 microns) is recommended.

Hand or Power Tool Preparation
Hand or power tool clean to a minimum SSPC-SP2 or St2 (ISO 8501-1:1988).
Note, all scale must be removed and areas which cannot be prepared adequately by chipping or needle gun
should be spot blasted to a minimum standard of SSPC-SP6 or Sa2 (ISO 8501-1:1988). Typically this would
apply to C or D grade rusting in this standard.

Ultra High Pressure Hydroblasting/Abrasive Wet Blasting
May be applied to surfaces prepared to SSPC-SP6 or Sa2.5 (ISO 8501-1:1988) which have flash rusted to no
worse than Grade HB2.5M (refer to International Hydroblasting Standards) or Grade SB2.5M (refer to
International Slurry blasting Standards). It is also possible to apply to damp surfaces in some circumstances.
Further information is available from International Protective Coatings.

Aged Coatings
Interseal 670HS is suitable for overcoating a limited range of intact, tightly adherent aged coatings. Loose or
flaking coatings should be removed back to a firm edge. Glossy finishes may require light abrasion to provide a
physical ‘key’.

Systems recommendation
Interseal 670HS will normally be applied to correctly prepared steel substrates. However, it can be used over
suitably primed surfaces. Suitable primers are:
• Intercure 200
• Interzinc 315
• Interplus 356
• Interplus 256
• Intergard 269

Where a cosmetically acceptable topcoat is required the following products are recommended:
• Intercryl 530
• Interfine 878
• Intergard 740
• Interthane 990
• Interfine 629HS
• Interfine 979
• Interthane 870

Required tools
Airless spray
Recommended
- Tip range 18-23 thou (0.45-0.58 mm)
- Total output fluid pressure at spray tip not
Maximum film build in one coat is best attained by airless spray. When applying by methods other than airless
spray, the required film build is unlikely to be achieved.

Application by air spray may require a multiple cross spray pattern to attain maximum film build. Low or high temperatures may require specific application techniques to achieve maximum film build.

Brush
Typically 4-5 mils (100-125 microns) can be achieved

Roller
Typically 3-4 mils (75-100 microns) can be achieved

How to use
Mixing

Material is supplied in two containers as a unit. Always mix a complete unit in the
proportions supplied. Once the unit has been mixed it must be used within the working
pot life specified.
(1) Agitate Base (Part A) with a power agitator.
(2) Combine entire contents of Curing Agent (Part B) with Base (Part A) and mix thoroughly with power agitator.

Thinner : GTA220 ou GTA415 
May be necessary at low temperatures. Do not thin more than allowed by local environmental legislation.

Drying time

Drying time - Low temperature
A winter grade curing agent is also available to enable more rapid cure at temperatures less than 50°F (10°C),
however this curing agent will give an initial shade variation and more rapid discoloration on weathering.
Interseal 670HS is capable of curing at temperatures below 32°F (0°C). However, this product should not be
applied at temperatures below 32°F (0°C) where there is a possibility of ice formation on the substrate.


Warning
In order to achieve optimum performance on hand prepared steel, the aluminum pigmented version should be
applied as a primer coat by brush to ensure thorough wetting out of the substrate by Interseal 670HS.

For water immersion service, surface preparation to a minimum of SSPC-SP10 or Sa2.5 (ISO 8501-1:1988) followed
by application of multi-coats of Interseal 670HS to a total minimum dry film thickness of 10 mils (250 microns)
is required.

If salt water is used in the wet blast process the resulting surface must be thoroughly washed with fresh water
before application of Interseal 670HS. With freshly blasted surfaces a slight degree of flash rusting is allowable,
and is preferable to the surface being too wet. Puddles, ponding and accumulations of water must be removed.

Interseal 670HS is suitable for overcoating intact, aged alkyd, epoxy and polyurethane systems. However, this
product is not recommended where thermoplastic coatings such as chlorinated rubbers and vinyls have
previously been used. Please consult International Protective Coatings for alternative recommendations.

Surface temperature must always be a minimum of 5°F (3°C) above dew point.

Level of sheen and surface finish is dependent on application method. Avoid using a mixture of application
methods whenever possible.

In common with all epoxies Interseal 670HS will chalk and discolor on exterior exposure. However, these
phenomena are not detrimental to anti-corrosive performance.

Premature exposure to ponding water will cause a color change, especially in dark colors.

Interseal 670HS can be used as a non-skid deck system by modification with addition of GMA132 (crushed
flint) aggregate. Application should then be to a suitably primed surface. Typical thicknesses will be between
20-40 mils (500-1,000 microns). Preferred application is by a suitable large tip hopper gun (e.g. Sagola 429 or
Air texture gun fitted with a 5-10 mm nozzle). Trowel or roller can be used for small areas. Alternatively, a
broadcast method of application can be used. Consult International Protective Coatings for further details.

Interseal 670HS is certified to ANSI/NSF Standard 61 (selected colors only). Consult International Protective
Coatings for further details. Certification is for tanks greater than 100 gallons (378.5 liters), for pipes which are 6
inches (15 cm) in diameter or greater and for valves which are 2 inches (5 cm) in diameter or greater.
