INTERCURE 200HS - PART B - 3.79L

Use
As a primer for steelwork intended for use in a wide range of environmental conditions including offshore, chemical and
petrochemical plants, industrial buildings, pulp and paper mills, power plants and bridges.
Suitable for overcoating within 7 hours in most climatic conditions hence speeding up production and throughput in
fabrication shops.
Provides quick cure even at low temperatures often encountered in maintenance painting.

Surface preparation
All surfaces 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.
Oil or grease should be removed in accordance with SSPC-SP1 solvent cleaning.

Abrasive Blast Cleaning
Abrasive blast clean to SSPC SP6 or Sa2½ (ISO 8501-1:2007). If oxidation has occurred between blasting and
application of Intercure 200HS the surface should be reblasted to the specified visual standard.
Surface defects revealed by the blast cleaning process should be ground, filled, or treated in the appropriate manner.
Intercure 200HS is suitable for application to blast cleaned surfaces which were initially to the above standard but
have been allowed to deteriorate under good shop conditions for up to 7-10 days. The surface may deteriorate to
Sa2 standard but must be free from loose powdery deposits.
A sharp, angular profile of 2-3 mils (50-75μm) should be achieved.

Shop Primed Steel
Weld seams and damaged areas should be blast cleaned to SSPC SP6 or Sa2½ (ISO 8501-1:2007).
If the shop primer shows extensive or widely scattered breakdown overall sweep blasting maybe necessary.

Systems compatibility
Intercure 200HS will normally be applied to suitably prepared steel, e.g. blast cleaned. However, if necessary,
application over prefabrication blast primers can be performed.

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
Do not thin more than allowed by local environmental legislation

Mix ratio :

Drying time


Cleaning tools
Clean all equipment immediately after use with International GTA 220 or 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.

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.

Warning
Intercure 200HS is preferred for use with systems for chemical environments where zinc based materials can be
subject to attack in both acidic and alkaline conditions.

Over-application should be avoided as thick films will not be as good a substrate for topcoat adhesion after ageing as
those at the specified thickness.

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

This product must only be thinned using recommended International GTA220 thinners. The use of alternative
thinners, particularly those containing ketones, can severely inhibit the curing mechanism of the coating.

At low temperatures, it may be necessary to thin Intercure 200HS to enable airless apray application to be
performed. Normally 2% thinning (by volume) with International GTA220 will be satisfactory for this purpose.

Intercure 200HS 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.

This product is not available in pale and pastel shades due to a tendency to discolour rapidly. Additionally, in
common with all epoxies Intercure 200HS will chalk on exterior exposure. However, these phenomena are not
detrimental to anti-corrosive performance.

Intercure 200HS is not intended for use as a primer for steelwork which may be subjected to continuous immersion
conditions.

Intercure 200HS can also be used as a primer for substrates other than blasted steel, e.g. stainless steel, alloys, etc.
Consult International Protective Coatings for further details.

Absolute measured adhesion of topcoats to aged Intercure 200HS is less than that to fresh material, however, it is
adequate for the specified end use.

Over-application of Intercure 200HS will extend both the minimum overcoating periods and handling times, and may
be detrimental to long term overcoating properties.

Excessive over application of material on areas such as poorly prepared welds may result in long term stress
cracking and so early failure.

Note: VOC values are typical and are provided for guidance purpose only. These may be subject to variation
depending on factors such as differences in color and normal manufacturing tolerances.

Low molecular weight reactive additives, which will form part of the film during normal ambient cure conditions, will
also effect VOC values determined using EPA Method 24.
