A zero VOC, two component, zinc rich water based alkali silicate with organic modification for improved film and application properties.
I n t e n d e d U s e s As a high performance galvanic primer for corrosive environments. Rapid curing, together with early water resistance and excellent resistance to handling damage, make this product ideal for use in fabrication yards, maintaining the versatility shown by the solvent based equivalents.
Can be overcoated with a wide range of high performance paint systems.

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 8504:1992.
Oil or grease should be removed in accordance with SSPC-SP1 solvent cleaning.
Abrasive Blast Cleaning
Abrasive blast clean to Sa2½ (ISO 8501-1:1988) or SSPC-SP6. If oxidation has occurred between blasting and application of Interzinc 250, 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.
A sharp, angular surface profile of 40-75 microns (1.5-3.0 mils) is recommended.

P r o d u c t
C h a r a c t e r i s t i c s
Apply by air or airless spray. Thoroughly flush equipment with International
GTA991 thinner or alcohol, followed by water prior to use.
To obtain maximum edge protection and film build, air or airless spray application is recommended. Contact International Protective Coatings for specific recommendation regarding airless spray pumps and spray guns.
With all water based coatings careful control of application conditions is required to ensure good long term performance. International Protective Coatings have available a set of working procedures relating to the application of water borne paints which are available on request.
The following basic parameters must be adhered to:
Interzinc 250 must be protected from freezing at all times during storage.
The minimum steel temperature for application must be above 10°C (50°F), and be at least 3°C (5°F) above dew point.
The relative humidity should be lower than 70% otherwise drying and overcoating times will be severely extended.
Good airflow is essential around the object being painted [minimum air speed
0.1m/sec (4 inches/sec)].
Minor areas which are difficult to ventilate should be brush applied to prevent overapplication.
Application below the minimum film forming temperature (M.F.F.T.) of the coating and/or poor ventilation will result in poor film coalescence and will result in a powdery cracked film which will require removal and re-application.
Excessive film thickness may lead to splitting of the film when overcoated with high build systems.
For high temperature systems the thickness of Interzinc 250 should be restricted to
50 microns (2mils) d.f.t. Continuous dry temperature resistance of Interzinc 250 is
400°C (752°F) if left untopcoated, however, if this product is used as a primer for
Intertherm 50, or Intertherm 601, the dry temperature resistance will be 540°C
(1004°F).
S y s t e m s
C o m p a t i b i l i t y
Interzinc 250 is only recommended for application to correctly prepared steel substrates as described in Surface Preparation section.
Interzinc 250 can be overcoated with:-
Intercure 420 (mist coat may be needed)
Intergard 269
Intergard 395
Intergard 401
Intergard 405
Intergard 410 (mist coat may be needed)
Intergard 475 HS (mist coat may be needed)
Intertherm 50
Intertherm 601
Intertherm 875
For other suitable topcoats, consult International Protective Coatings.
