Interline 982 Blast Holding Primer is an epoxy paint used as a primer. As a multi-functional primer, it allows full utilization of the dehumidification equipment employed during tank lining application. A two-component epoxy holding primer. Although the low molecular weight reactive additive becomes part of the film when cured under normal ambient conditions, it also affects the VOC value as determined by EPA Method 24 analysis. Parameters on this page: DFT 15–40 µm (0.6–1.6 mil), theoretical spreading rate 12 m²/L, number of components two-component.

All surfaces to be coated must be clean, dry and free of contaminants. Before painting, all surfaces must be assessed and prepared in accordance with ISO 8504:2000.
Where required, 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.
Abrasive blast cleaning to Sa2½ (ISO 8501-1:2007) or SSPC-SP10. If oxidation occurs between blast cleaning and application of Interline 982, the surface shall be reblasted to the specified visual standard.
Surface defects exposed during abrasive blasting must be ground, filled or treated by a suitable method.
For thin-film systems, an angular surface profile of 50–75 µm (2–3 mil) is recommended.
For heavy-duty and glass-fibre reinforced systems, an angular surface profile of 75–100 µm (3–4 mil) is recommended.
This product is not recommended for hand-prepared steel.
| Mixing | Interline 982 shall be applied in accordance with International Paint's detailed "Application Procedure" for tank lining materials. |

|---|---|
| Interruption of work | Paint shall not be left in hoses, spray guns or spray equipment. Release pressure from the paint hose and thoroughly flush fluid hoses and spray gun with International GTA822. Do not re-pressurize the equipment before continuing spray operations, and ensure compliance with the specified pot life limits. |
| Cleaning | All equipment shall be cleaned with International GTA 822 immediately after use. Periodic flushing of spray equipment during the working day is good practice. Flushing frequency depends on spray volume, temperature, spraying time and delays. |
All surplus paint and empty containers must be disposed of in accordance with the appropriate local laws/regulations.
Interline 982 maintains the blast in a semi-protected environment on tank interiors for up to 28 days. If moisture is present on the surface, oxidation occurs and reblasting is required.
Heavily pitted areas should be pre-coated by brush to ensure good surface wetting.
The surface temperature must always be maintained at least 3 °C (5 °F) above the dew point.
Do not apply when the steel temperature is below 10 °C (50 °F).
This product does not cure adequately below 5 °C (41 °F). For optimum performance, curing should take place above 10 °C (50 °F).
Ensure adequate ventilation when applying Interline 982 in confined spaces.
Unacceptably low temperature and/or high humidity during or immediately after application leads to incomplete curing and surface contamination, compromising intercoat adhesion.
DFT above 40 µm (1.6 mil) or below 15 µm (0.6 mil) adversely affects film appearance and performance.
For heavy-duty and GRP systems, excessively thick films shall be avoided; where a primer is required, a thickness of 15–25 µm (0.6–1.0 mil) shall be specified. To achieve this DFT, Interline 982 may be thinned by up to 25%.
Over-application of Interline 982 extends the minimum recoat time and handling time and adversely affects long-term recoatability.
This product holds the following approvals: • BS6920 water fittings and local regulations, as primer for Interline 925. Note: VOC values are typical and for guidance only. Values may vary with colour differences and normal manufacturing 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.
The following topcoats are recommended for use with Interline 982:
| Interline 850 | Interline 983 |
|---|---|
| Interline 921 | Interline 984 |
| Interline 925 | Interline 985. Consult International Paint to confirm that Interline 982 is suitable for contact with the product to be stored. |

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, provide adequate ventilation to keep solvent concentrations within safe limits and prevent fire and explosion (for general drying times, see the product data sheet). Forced ventilation is required in confined spaces. During application and drying, personal ventilation and/or 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 Health and Safety section of the Material Safety Data Sheet and the application procedure for the product (for two-component coatings, those of the base and curing agent).
If welding or flame cutting is performed on metal substrate 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 the International Paint Protective Coatings division.
