Interthane 1070 High-Build Polyurethane is a polyurethane coating. Suitable for moderately corrosive environments, e.g. category C3 as defined by ISO 12944-2:1998. A two-component, high-build acrylic polyurethane primer/topcoat containing zinc phosphate anticorrosive pigment, providing excellent durability and long-term recoatability. Although low-molecular-weight reactive additives become part of the film when cured under normal environmental conditions, they also affect the VOC value as found by EPA Method 24 analysis. Parameters on this page: volume solids 56% ± 2% depending, dry film thickness 150-200 µm (6-8 mil), theoretical spreading rate 2.80 m²/L.

All surfaces to be coated must be clean, dry and free of contaminants. Before application, all surfaces must be assessed and prepared in accordance with ISO 8504:2000. Remove oil and grease in accordance with the SSPC-SP1 solvent cleaning standard.
Blast cleaning: blast clean to at least Sa 2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation occurs between blast cleaning and application of Interthane 1070, the surface should be re-blasted to the specified visual standard. Surface defects exposed by blast cleaning should be ground, filled or treated by other suitable methods.
Recommended surface roughness is 50 µm (2 mil).

|---|---|
| Interruption of work | Do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with International thinner. Once mixed, paint should not be resealed; if work is interrupted for too long, mix a fresh batch for application. |
| Cleaning | All equipment should be cleaned immediately after use with International thinner. Flushing spray equipment periodically during daily work is good practice. Cleaning frequency depends on the volume sprayed, temperature, spraying time, including interruptions, and other factors. |
All surplus paint and empty containers must be disposed of in accordance with the relevant local laws/regulations.
Gloss and surface evenness depend on the application method. Avoid mixing different application methods as far as possible.
Apply by airless spray to achieve the maximum film thickness per coat. Application methods other than airless spray cannot achieve the required film thickness. With air spray, several cross coats are required to achieve the maximum film thickness. At low or high temperatures, special application techniques may be required to achieve the maximum film thickness.
When applying Interthane 1070 by brush or roller, multiple coats are necessary to achieve the specified total dry film thickness of the system.
Applicators should be aware that the ability of Interthane 1070 to be applied in a single coat is affected by the substrate temperature. At higher steel temperatures, the film thickness is lower and a thinner coating is obtained.
This product must be thinned only with the recommended International thinner. Other thinners, especially alcohol-containing thinners, severely inhibit the curing process.
Do not apply when the steel temperature is below 5 °C (41 °F). When applying Interthane 1070 in confined spaces, ensure adequate ventilation.
Condensation on the surface during or after application will cause loss of gloss and a poor-quality film.
Premature exposure to standing water may cause colour change, especially for dark colours and at low temperatures.
The intercoat adhesion on aged Interthane 1070 is reduced relative to that on a fresh coating, but still meets the needs of the intended use.
This product is not recommended for immersion service. If severe chemical or solvent splashes are likely, contact International Paint for information on suitability.
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
Although the low-molecular-weight reactive additive becomes part of the film when cured under normal ambient conditions, analysis by EPA Method 24 shows that it also affects the VOC value.
Interthane 1070 is designed as a coating for direct contact with metal.
Suitable topcoats are: Interthane 990, Interthane 1070. For more system compatibility advice, contact International Paint Protective Coatings.
