Low-temperature Spill Protection Coating TB550 (0L9)
Two-component solvent-free amine-cured synthetic epoxy insulating coating. Provides thermal insulation and anti-corrosion protection. Suitable for continuous operating temperatures from -40°C to 150°C. Can be used alone or together with Jotachar epoxy passive fire protection coating.
Typically used in the oil, gas and energy industries. Suitable for offshore and coastal environments.
Resistance to cryogenic liquid spillage:
When applying Jotatherm TB550, it acts only as part of the system to resist embrittlement of the substrate caused by spillage of cryogenic liquids such as LNG.
The Jotatherm CSP1 mesh shall be applied as described in the Jotatherm TB550 application guide to resist cryogenic liquid spillage.
Fire protection:
Can be used in combination with Jotachar epoxy passive fire protection coating to reduce substrate surface temperature to below 80°C, protecting Jotachar against heat radiation from the substrate.
Thermal insulation:
Can be used to reduce substrate temperature to provide personnel protection. Provides thermal insulation and corrosion protection under insulation. Suitable for continuous operating temperatures from -40°C to 150°C.

The data listed are based on factory batch production and may vary slightly with colour.
Application specific gravity (ISO 1183:1987 Method A): 0.57 g/cm³.
Typical recommended specification range:
Dry film thickness:
2–40 mm (depending on application purpose and specific project requirements)
Spray application:
| Typical maximum film thickness achievable per coat | 5 mm |
|---|
Manual application:
| Typical maximum film thickness achievable per coat | 25+ mm |
|---|
Film thickness depends on the shape and structure of the steel structure, surrounding environment, pump type and settings, primer used and other factors.
Absolute maximum DFT is the highest DFT achievable after application without sagging.
To ensure lasting adhesion of the next coat, all surfaces must be clean, dry and free of contaminants.

| Dry/cured to service | 36 h | 12 h | 6 h | 3 h |
For the maximum recoat interval, refer to the Application Guide (AG) for this product.
Drying and curing times are determined based on temperature and relative humidity below 85%, with dry film thickness within the average range.
| 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 | 40 min | 25 min |
The given parameters apply to trowel application and roller application.
The working pot life does not apply to two-component spray equipment, as the materials are mixed within the spray gun during application. For manual application, mixed material shall be used as soon as possible. As the reaction is exothermic, the larger the mixed quantity, the shorter the pot life.

When used primarily as a primer or antifouling coating, products may show slight colour variation from batch to batch. Such products, and epoxy products used as topcoats, may chalk when exposed to sunlight.
Gloss and colour retention of topcoats depend on the colour type, the surrounding environment such as temperature and UV intensity, application quality and product type. Contact your local JOTUN office for further information.
