Jotachar 1709
This is a two-component, solvent-free, amine-cured, 100% solids epoxy intumescent coating. Specially designed intumescent fire protection coating providing fire protection for various types of steel structures and equipment exposed to hydrocarbon pool fires. No additional reinforcing mesh is required. Used as a primer or intermediate coat in atmospheric environments. Suitable for carbon steel, aluminium, hot-dip galvanized steel and stainless steel substrates with approved primer treatment.
Commonly used in the oil, gas and energy industries. Based on test certificates, suitable for passive fire protection of carbon steel, stainless steel, GRP and concrete structures in offshore and onshore environments.
Meeting all epoxy intumescent fire protection technologies, the product is suitable for pipelines, vessels or equipment. At higher service temperatures, Jotatherm TB550 is used as an insulating layer between the substrate and Jotachar, or over Jotachar, to isolate the surface from atmospheric heat radiation.

Typical recommended specification range
Dry film thickness:
4–30 mm (depending on service conditions and project requirements)
Theoretical spreading rate:
1 kg of Jotachar 1709 at 1 mm film thickness covers 1 m² (applied with two-component pump)
Typical film thickness of the first coat can reach 5.5 mm.
Subsequent coats, continuous application film thickness can reach 10 mm, depending on atmospheric conditions; normally application can continue 60 min after completion of the first coat.
Depending on the member structure, shape, application environment, pump type and settings, and primer type, higher film thicknesses can be achieved with this product.
The maximum wet film thickness is the highest film thickness at which the coating system can be applied without sagging.
Surface Preparation
| Substrate | Minimum | Recommended |
| Coated surface | A clean, dry and sound compatible primer. | |
This product may be applied by the following methods
| Spray: | Use two-component heated plural-component spray equipment or modified airless spray equipment (with a heater). For further information, see the Application Guide. Note: all spray pumps used for this product must be approved by JOTUN |
| Trowel: | For further information, see the Application Guide. |

| Jotachar 1709 Comp B — Exterior Intumescent Fire Protection for Structural Steel 1709, Component B | 1 part |
Each component must be stored at 25–30 °C (77–86 °F) for 24 hours. Stir or mix thoroughly with a power mixer before application.
| Thinner: | Jotun Thinner No. 7 | /Jotun Thinner No. 17 |

| Maximum thinning: | 5 % |
Typical dilution volume ratio for modified airless spray or manual application is 2–3%. For roller application, use JOTUN Thinner No. 7 and No. 17.
| Note | Where the Korean VOC regulation (Clean Air Conservation Act) and its corresponding thinning limits differ from the recommended thinning volume, the former prevails. |

| Cleaner | Jotun Thinner No. 17 |
When the thinner is used as a cleaning solvent, it must first comply with local regulatory requirements
| Nozzle tip size (inch/1000): | 31-41 |
| Nozzle pressure (minimum): | 200 bar/2900 psi |
| Substrate Temperature | 5 °C | 15 °C | 23 °C | 40 °C |
| Touch Dry | 6 h | 3 h | 1 h | |
| Walk-on Dry | 24 h | 12 h | 6 h | 3 h |
| Minimum recoat interval | 6 h | 3 h | 2 h | 1 h |
| Dry/cured to service | 24 h | 12 h | 6 h | 3 h |
For the maximum recoat interval, refer to the Application Guide (AG) for this product.
The minimum drying recoat interval is for self-recoating. See the additional guidance for the finish coat.
Drying and curing times are determined based on temperature and relative humidity below 85%, with dry film thickness within the average range.
Topcoat
The system should be dry to handle, and the coating thickness gauge must not leave indentations. Before applying the topcoat, the applicator must ensure the specified dry film thickness has been achieved.
| Touch Dry | The state at which light finger pressure leaves no mark or stickiness. |
|---|---|
| Walk-on Dry | The minimum time after which the coating allows normal foot traffic without leaving permanent footprints, marks or other physical damage. |
Minimum recoat interval after drying: the recommended minimum interval before applying the next coat.
Dry/cured to service: the minimum time before the coating can be permanently exposed to a specific environment/medium.
| Paint temperature | 15 °C | 23 °C |
| Pot Life | 45 min | 40 min |
The above data apply to trowel and roller application. With two-component pump application, the coating is mixed at the gun, so the pot life does not apply. With single-component pump and manual application, use the mixed product as soon as possible. Because mixing is exothermic, the larger the mixed quantity, the shorter the pot life.
Drying, atmospheric
| Continuous | 95 °C |
|---|
Can be used without topcoat up to 95 °C. In the temperature range of 95 °C to 120 °C, a suitable topcoat is required. Subject to technical assessment; contact Jotun.
May be used together with Jotatherm TB550 as an insulating layer at 95 °C to 150 °C. Subject to technical review; contact JOTUN.
Above 150 °C, use an alternative thermal insulation solution.
| Vent container to release vapour | Up to 180 °C for a duration not exceeding 24 hours. |
|---|---|
| Oil and gas flares | Up to 120 °C to accommodate accidental and infrequent surface temperature rises on operating gas flares at offshore and onshore facilities, for durations not exceeding 60 minutes. |
At high temperatures, appearance may be affected; this can be reduced by selecting a suitable topcoat.
Depending on the actual exposure conditions in service, this product may be used with various primers and topcoats. Some reference systems are listed below. For specific systems, contact JOTUN.
| Previous coat: | Epoxy, zinc epoxy, epoxy zinc phosphate, modified epoxy |
| Subsequent coat: | Cross-linked acrylic, polyurethane, polysiloxane, epoxy |
Primers used beneath this product must be approved by JOTUN. Consult JOTUN for the latest approved primer list.
