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.
Blast cleaning: for ideal performance, Enviroline 225 must be applied over surfaces blast cleaned to Sa 3 (ISO 8501-1:2007) or SSPC-SP5. If not used in high-temperature and/or harsh environments, Enviroline 225 can be used over surfaces blasted to Sa 2½ (ISO 8501-1:2007) or SSPC-SP10. Consult International Paint Protective Coatings for details.
Recommended surface roughness 75–125 µm (3–5 mils).
Enviroline 225 must be applied before the steel surface oxidises. If oxidation has occurred, the oxidized area should be fully re-blasted to the specified standard.
Blast cleanliness can be maintained by dehumidification, or an approved temporary primer can be applied.
For concrete surfaces, consult the International Paint Protective Coatings division for professional advice.
| Mixing | This product is supplied in two containers as one unit. The entire unit should be stored, mixed and applied in accordance with the Enviroline Application Guide. |
|---|---|
| Mixing ratio | 2 parts : 1 part (by volume) |
| Pot life | 40 °C (104 °F), 10 min |
| Plural-component airless spray | Recommended | For further information, refer to the Enviroline Application Guide. |

| Air Spray | N/A |
(with pressure pot)
| Brush | Applicable | For small-area repair or touch-up of welds and edges. |
| Thinner | Generally not required | For specific advice, refer to the Enviroline Application Guide. |
| Cleaner | Enviroline 71C |
| 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 a brief guide to the use of Enviroline 225. Specific project requirements depend on the final use and service conditions of the tank or container. Always consult International Paint Protective Coatings to confirm whether Enviroline 225 is suitable for contact with the product to be stored.
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, baking can be carried out to accelerate curing or enhance chemical resistance under extremely corrosive environmental conditions. To achieve maximum chemical resistance, the baking time is at least 2 hours at 121 °C (250 °F), or 6–8 hours at 66 °C. When immersed in sulphuric acid of 93% or higher concentration, Enviroline 225 must be post-cured.
The maximum continuous dry heat resistance temperature of Enviroline 225 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 225 should always be applied over correctly prepared substrates. When a primer is required as part of the coating system, consult International Paint Protective Coatings for professional advice.
Enviroline 225 is a single-coat system. If necessary, it must only be self-overcoated 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.
