All surfaces to be coated must be clean, dry and free of contamination. Before painting, 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.
For optimum performance on steel substrates, Enviroline 125U must be applied to surfaces abrasive blast cleaned to Sa3 (ISO 8501-1:2007) or SSPC-SP5. Where not used in high-temperature and/or severe environments, Enviroline 125U may be applied to surfaces abrasive blast cleaned to Sa2½ (ISO 8501-1:2007) or SSPC-SP10. Consult International Protective Coatings for details.
Recommended surface roughness 75–125 µm (3–5 mils).
Enviroline 125U must be applied before oxidation of the steel surface occurs. If oxidation has occurred, all oxidized areas shall be re-blasted to the specified standards 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.
For professional advice on concrete substrates, consult International Protective Coatings.

| Cleaner | Enviroline 71C / International GTA203 |
|---|---|
| Interruption of work | Do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with Enviroline 71C. Once mixed, paint should not be resealed. If work is interrupted for a long time, use a freshly mixed batch when resuming. |
| Cleaning | Clean all equipment immediately after use with Enviroline 71C. Flushing spray equipment periodically during daily work is good practice. Cleaning frequency depends on the volume sprayed, temperature and time, including all delays. |
Surplus paint and empty containers must be disposed of in accordance with the relevant laws/regional regulations.
Read the Enviroline Application Guide carefully before use.
This data sheet provides brief guidance for the use of Enviroline 125U. The requirements of a specific project depend on the end use and operating conditions of the tank or vessel. Always consult International Protective Coatings to confirm the suitability of Enviroline 125U 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 airless spray, heat the components to 35–37 °C (95–100 °F) before mixing for optimum performance. | For multi-component airless spray application, the product may be heated before application for optimum results: Component A (resin) up to 60 °C (140 °F), Component B (curing agent) up to 40 °C (105 °F). |

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.
Enviroline 125U resists a maximum continuous dry temperature of 149°C (300°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 125U shall always be applied to properly prepared substrates. Where a primer is required as part of the coating system, consult International Protective Coatings for professional advice.
Enviroline 125U is a single-coat system. Where necessary, it shall only be self-recoated or self-repaired.

This product is intended for professional applicators in industrial use only.
All work, including the application and use of this product, must comply with the relevant national standards, laws and regulations on safety, health and environmental protection.
During application and the subsequent drying period (for common drying times, see the product data sheet), provide adequate ventilation to keep solvent concentrations within safe limits and prevent fire and explosion. Forced ventilation is required in confined spaces. During application and drying, personal ventilation and respiratory protection (e.g. air-fed hood or suitable filter mask) must also be provided.
Take the necessary measures to prevent skin and eye contact with the coating (e.g. protective clothing, gloves, goggles, mask, barrier cream).
Before use, read and follow the Material Safety Data Sheet and the Health and Safety section of the application procedure for this product (for two-component coatings, those of the base and curing agent).
If welding or cutting is performed on metal substrate previously coated with this product, dust and fumes will be released; use suitable personal protective equipment and local exhaust ventilation.
The specific safety measures depend on the application method and working environment. If these warnings or instructions are not fully understood or cannot be strictly observed, do not use the product and consult International Paint.
Warning: this product contains liquid epoxy and modified polyamines and may cause skin sensitisation if handled improperly.
