Product A low VOC, high solids, high build, two component epoxy coating. Available with
Description conventional pigmentation, or alternatively can be pigmented with micaceous iron
oxide to provide enhanced overcoating properties.

Intended Uses For use as a high build epoxy coating to improve barrier protection for a range of
anti-corrosive coating systems in a wide range of environments including offshore
structures, petrochemical plants, pulp and paper mills and bridges.
Suitable for use in both maintenance and new construction situations as part of an
anti-corrosive coating system.
The micaceous iron oxide variant improves long term overcoating properties, better
facilitating application in the fabrication shop, prior to shipping, with final overcoating
on site.

Practical Color Light gray MIO and a selected range of colors

Surface All surfaces to be coated should be clean, dry and free from contamination. Prior to
Preparation paint application all surfaces should be assessed and treated in accordance with
ISO 8504:1992.
Primed Surfaces
Intergard 475 HS should always be applied over a recommended anti-corrosive coating
scheme. The primer surface should be dry and free from all contamination, and
Intergard 475 HS must be applied within the overcoating intervals specified (consult the
relevant product data sheet).
Areas of breakdown, damage etc., should be prepared to the specified standard (e.g.
SSPC-SP6 or Sa2½ (ISO 8501-1:1988), Abrasive Blasting, or SSPC-SP11, Power Tool
Cleaning) and patch primed prior to the application of Intergard 475 HS.
Zinc Primed Surfaces
Ensure that the surface of the primer is clean, dry and free from contamination and zinc
salts before application of Intergard 475 HS. Ensure zinc primers are fully cured before
overcoating.

Application 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.
Mix Ratio 3 parts : 1 part by volume
Working Pot 50°F (10°C) 59°F (15°C) 77°F (25°C) 104°F (40°C)
Life 60 minutes 60 minutes 60 minutes N/A
Airless Spray Recommended - Tip range 21-25 thou (0.53-0.63 mm)
- Total output fluid pressure at spray tip not
less than 2,700 p.s.i. (190 kg/cm2)
Air Spray Recommended Gun DeVilbiss MBC or JGA
(Pressure Pot) Air Cap 704 or 765
Fluid Tip E
Brush Suitable Typically 3 mils (75 microns) can be
achieved
Roller Suitable Typically 3 mils (75 microns) can be
achieved
Thinner International GTA007 Do not thin more than allowed by local
environmental legislation.
Cleaner International GTA415
(or GTA822)
Work Stoppages Do not allow material to remain in hoses, gun or spray equipment.
Thoroughly flush all equipment with International GTA415. Once
units of paint have been mixed they should not be resealed and it is
advised that after prolonged stoppages work recommences with
freshly mixed units.
Clean Up Clean all equipment immediately after use with International GTA415.
It is good working practice to periodically flush out spray equipment
during the course of the working day. Frequency of cleaning will
depend upon amount sprayed, temperature and elapsed time,
including any delays.
All surplus materials and empty containers should be disposed of in
accordance with appropriate regional regulations/legislation.

Product Intergard 475 HS is primarily designed for use as a high build barrier coat to impart
Characteristics barrier protection to a coating system. It is recommended that it should be overcoated
with a durable finish from the Interfine or Interthane range when appearance is
important.
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 conventional 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.
When applying Intergard 475 HS by brush or roller, it may be necessary to apply
multiple coats to achieve the total specified system dry film thickness.
Surface temperature must always be a minimum of 5°F (3°C) above dew point.
If applying Intergard 475 HS in confined spaces ensure adequate ventilation.
Exposure to unacceptably low temperatures and/or high humidities during, or
immediately after, application may result in incomplete cure and surface contamination
that could jeopardize subsequent intercoat adhesion.
Elevated Temperature Curings
An alternative curing agent is available for applications at temperatures greater than
77°F (25°C).
Overcoating Interval with
recommended topcoats
Temperature Touch Dry Hard Dry Minimum Maximum

77°F (25°C) 90 minutes 6 hours 6 hours Extended*

104°F (40°C) 60 minutes 2 hours 2 hours Extended*
* See International Protective Coatings Definitions and Abbreviations
Interchanging standard and elevated temperature curing agents during application to a
specific structure will give rise to an observable color change due to the difference in the
yellowing/discoloration process common to all epoxies on exposure to UV light.
In common with all epoxies Intergard 475 HS will chalk and discolor on exterior
exposure. However, these phenomena are not detrimental to anti-corrosive
performance.
Intergard 475 HS is not designed for continuous water immersion.
The micaceous iron oxide variant of this product is frequently used as a “travel coat”
prior to final overcoating on site. To ensure best extended overcoating properties,
ensure over-application does not occur and that the surface is fully cleaned of any
contamination which may be present in the surface texture due to the coarse nature of
the micaceous iron oxide pigmentation.
When applying Intergard 475 HS at temperatures less than 59°F (15°C) or wet film
thicknesses of 6 mils (150 microns) or less, addition of around 5% International GTA007
thinners will improve film appearance, sprayability and aid film thickness control.

Compatibility Intercure 200 Interzinc 12 (mist coat or tie coat recommended)*
Intergard 251 Interzinc 22 (mist coat or tie coat recommended)*
Intergard 269 Interzinc 42
