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. Where necessary, remove weld spatter and grind welds and sharp edges smooth.
Oil and grease must be removed in accordance with the SSPC-SP1 solvent cleaning standard.
Steel substrate: for optimum performance, Enviroline 376F-30 must be applied to a surface prepared by abrasive blasting to Sa3 (ISO 8501-1:2007) or SSPC-SP5. If not for use in high-temperature and/or severe environments, Enviroline 376F-30 may be applied to a surface with an abrasive blasting result of Sa2½ (ISO 8501-1:2007) or SSPC-SP10. For details, consult the International Protective Coatings department.
Recommended surface roughness 75–125 µm (3–5 mils).
Enviroline 376F-30 must be applied before oxidation of the steel surface occurs. If oxidation has occurred, all oxidized areas shall be re-blasted to the standards specified above.
Surface defects exposed by blasting must be ground, filled or treated by a suitable method.
Blast cleanliness can be maintained by dehumidification, or an approved temporary primer can be applied.
The concrete substrate must be well cured before flooring, lining or coating application. Refer to the concrete surface preparation guide for further information.

| Cleaning | Clean all equipment with Enviroline 71C or International GTA203 immediately after use. Periodically flushing spray equipment during the working day is good practice. The frequency of cleaning depends on the quantity sprayed, temperature and elapsed time, including delays. |
All surplus material and empty containers must be disposed of in accordance with local laws and regulations.
Read the Enviroline Application Guide carefully before use.
This datasheet provides a brief guide to the use of Enviroline 376F-30. The requirements of a specific project depend on the end use and service conditions of the tank or vessel. Always consult the International Protective Coatings department to confirm the suitability of Enviroline 376F-30 with the stored product.
Always follow the detailed coating specification recommended by the International Paint Protective Coatings division.
Touch-up is a fundamental requirement of good working practice; it should be part of any lining system.
For heavily pitted or porous steel, apply about 50% of the required film thickness by spray, then immediately roll with a short-nap roller or squeegee to work the coating into the bottom of pits.
For plural-component airless spray, the product may be heated before application for best results: Component A (resin) to a maximum of 60 °C (140 °F), Component B (curing agent) to a maximum of 40 °C (105 °F). For airless spray, heating each component to 35–37 °C (95–100 °F) before mixing gives optimum performance.
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point.
For the ideal temperature conditions, see the table below. Throughout curing, in addition to meeting these conditions, adequate ventilation must be maintained.
Substrate; environment
| Ideal 21–49 °C (70–120 °F) | 21-38 °C(70-100°F) |
|---|---|
| Minimum 13 °C (55 °F) | 13 °C (55 °F). After the coating system is fully cured, check the minimum thickness of the system using a non-destructive magnetic gauge. The entire system must be free of pinholes and bare spots. The cured film must be free of sags, runs, drips, inclusions or other defects. All defects and deficiencies must be repaired. Repaired areas must be retested and fully cured before the lining is put into service. |
Although baking is not required in most applications, it may be used to accelerate curing or improve chemical resistance in extremely corrosive environments. For maximum chemical resistance, bake at 121 °C (250 °F) for at least 2 hours, or at 66 °C for 6–8 hours.
The maximum continuous dry heat resistance temperature of Enviroline 376F-30 is 177 °C (350 °F).
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.
Enviroline 376F-30 should always be applied to a properly prepared substrate. When a primer is required as part of the coating system, consult the International Protective Coatings department for professional advice.
Enviroline 376F-30 is a single-coat system. Where necessary, it must only be self-recoated or self-repaired.
