International Interthane 3230HG

International Interthane 3230HG is a two component, high gloss, low VOC, high solids, fast curing, acrylic polyurethane primer / finish pigmented with zinc phosphate to provide added anti-corrosive performance and a durable, decorative finish.

Best Uses

International Interthane 3230HG is specifically designed as part of the International 3200 product series for use as a single or two coat primer/finish coating system to protect construction and mining heavy machinery, agricultural equipment, railcars, transportation vehicles, material handling and lifting equipment, pumps, valves, gear units and other small motors and machinery.

Interthane 3230HG is particularly suited for use as a rapid drying system for fast handling times and
maximising the production throughput. This contributes to lower energy consumption and stoving
emissions at or below 40ºC compared to conventional alkyd enamel products which typically requires
force drying above 40ºC.

The main features of Interthane 3230HG are:

• Good adhesion properties over correctly prepared steel, galvanised steel and stainless steel
• Lead chromate free
• Quick handling times and fast drying at high volume solids
• Good gloss and colour retention
• Versatile application thickness to allow single or two coat applications

Application

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. Suitable for use over phosphate washed steel.

Steel
Abrasive blast clean to a minimum of Sa2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation has occurred between blasting and application of Interthane 3230HG the surface should be re-blasted to the specified visual standard. Surface defects revealed by the blast cleaning process should be ground, filled, or treated in the appropriate manner. A surface profile of 40-60 microns (1.6-2.4 mils) is recommended. Lower surface profiles of 20-30 microns (0.8-1.2 mils) can be used to improve the overall aesthetics of the overall paint system.

Stainless Steel, Galvanised Steel and Aluminium
Remove dirt and oils by solvent cleaning or other suitable detergent/cleaner followed by a thorough water rinsing. Sand or abrasive sweep blast to a standard similar to ISO 8501-1:2007 Sa1 or SSPC SP7 to create a surface profile.

Primed Surfaces
The primer surface should be dry and free from all contamination and Interthane 3230HG 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 and patch primed prior to the application of Interthane 3230HG.

Apply via airless or air spray.

Compatibility

Interthane 3230HG can be applied directly to abrasive blast cleaned surfaces. However, when improved anti-corrosive performance is required the following primers are recommended:

• Intergard 3210

Interthane 3230HG may be overcoated with itself or the following topcoats:

• Interthane 3230G
• Interthane 3230HG
• Interthane 3230M
• Interthane 3230SG
