What it is and why choose it
INTERTHANE 3230HG PART A INDIVISIBLE KIT is the base component (Part A) of Interthane 3230HG, a two-component, high gloss, acrylic polyurethane primer/finish. When mixed with its curing agent (Part B), it provides a low VOC, high solids, fast curing coating pigmented with zinc phosphate for enhanced anti-corrosive performance and a durable, decorative finish.
It is specifically designed as part of the International 3200 product series for OEM environments where rapid drying, high production throughput and reliable corrosion protection are required. Typical substrates include correctly prepared steel, galvanised steel and stainless steel.
Main features

- High volume solids (62% ± 2%) for good film build and coverage.
- Fast curing with quick handling times, even at relatively low stoving temperatures (around or below 40°C).
- Good adhesion to correctly prepared steel, galvanised steel and stainless steel.
- Lead chromate free formulation.
- Good colour and gloss retention for a long-lasting decorative appearance.
- Versatile film thickness, suitable for single or two-coat systems.
- Suitable for automated paint application and forced curing processes.
- Designed for light industrial steelwork in internal dry or low-corrosivity environments (ISO 12944 C1, C2 and C3).

Applications and use cases
Typical industrial uses
- Construction and mining heavy machinery
- Agricultural equipment
- Railcars and other rail transportation vehicles
- General transportation vehicles
- Material handling and lifting equipment
- Pumps, valves and gear units
- Other small motors and machinery
- Light industrial steelwork in internal dry environments
- Exposed steelwork in low corrosivity environments (ISO 12944 C1, C2 and C3)
Suitable substrates
- Correctly prepared carbon steel (including abrasive blast cleaned or phosphate washed steel)
- Stainless steel, galvanised steel and aluminium (after suitable cleaning and surface profiling)
- Appropriately primed surfaces within the specified overcoating interval
Surface preparation overview
- Steel: Abrasive blast to a minimum of Sa2½ (ISO 8501-1:2007) or SSPC-SP6. Repair any surface defects revealed by blasting.
- Stainless, galvanised steel and aluminium: Remove dirt and oil by solvent or suitable detergent cleaning followed by thorough water rinsing, then sand or sweep blast to a standard similar to ISO 8501-1:2007 Sa1 or SSPC SP7 to create a surface profile.
- Primed surfaces: Ensure the primer is dry and clean; repair breakdown or damage and patch prime before applying Interthane 3230HG.
System compatibility
- Can be applied directly to abrasive blast cleaned steel.
- For improved anti-corrosive performance, the following primer is recommended: Intergard 3210.
- May be overcoated with:
- Interthane 3230G
- Interthane 3230HG
- Interthane 3230M
- Interthane 3230SG
FAQ
1. What type of coating system is Interthane 3230HG?
It is a two-component, acrylic polyurethane primer/finish designed to function as a single- or two-coat system for industrial steelwork and machinery.
2. On which substrates can it be applied?
It can be applied to correctly prepared steel, galvanised steel, stainless steel, aluminium and suitably primed surfaces, following the specified surface preparation procedures.
3. What film thickness is recommended?
The recommended dry film thickness is 60–100 microns (2.4–4 mils), corresponding to 97–161 microns (3.9–6.4 mils) wet.
4. Is Interthane 3230HG suitable for fast production lines?
Yes. It is specifically suited to rapid drying and fast handling, helping to maximise production throughput, particularly in automated application and forced curing processes.
5. What environments is it suitable for?
It is most suitable for light industrial steelwork in internal dry environments and exposed steelwork in low corrosivity environments corresponding to ISO 12944 C1, C2 and C3.
6. How should the product be mixed?
Mix one complete unit in the supplied proportions: 6 parts Base (Part A) to 1 part Curing Agent (Part B) by volume, using a power agitator for thorough mixing.
7. What is the pot life after mixing?
Pot life is approximately 7 hours at 15°C, 4 hours at 25°C and 2 hours at 40°C.
8. Which application methods are recommended?
Recommended methods are airless spray, air assisted airless spray, conventional air spray (pressure pot) and plural component airless spray. Brush and roller are suitable for small areas.
9. What thinner and cleaner should be used?
International GTA713 is recommended both as thinner (within local environmental limits) and as cleaner for equipment.
10. Does early exposure to water affect performance?
Premature exposure to ponding water may cause a permanent colour change; this is cosmetic only and does not affect the anti-corrosive protection.
