Balloxy BT

Product description

A two component, surface tolerant, abrasion resistant, high solid polyamine cured epoxy based coating.

Recommended use

Designed as an all year maintenance product for water ballast tanks. Can be used for properly prepared carbon steel and a range of aged coating surfaces as primer, midcoat, finish or as single coat system in atmospheric and immersed environments. It can be applied at sub zero surface temperatures.

  Surface preparation

   

  All surfaces should be clean, dry and free from contamination. The surface should be assessed and treated in accordance with ISO 8504.

  Bare steel

  Cleanliness: Power tool cleaning to min. St 2, mill scale free (ISO 8501-1:2007) and a roughness between 35 - 50 microns. Improved surface treatment (blast cleaning to Sa 2½) will improve the performance.

  Shopprimed steel

  Clean, dry and undamaged approved shopprimer.

  Coated surfaces

  Clean, dry and undamaged compatible primer. Please contact your local Jotun office for more information.

  Other surfaces

  The coating may be used on other substrates. Please contact your local Jotun office for more information.

  Condition during application

  The coating could be applied down to -10°C surface temperature. Temperature of the substrate should be minimum 3°C above the dew point of the air, temperature and relative humidity measured in the vicinity of the substrate. Good ventilation is required in confined areas to ensure proper drying and curing. Do not use heated air until the solvents have evaporated from the paint film to avoid surface drying and solvent entrapment. The coating should not be exposed to oil, chemicals or mechanical stress until cured. During application and the initial drying of the coating, the coating should not be exposed to high humidity as this can result in loss of gloss and an inferior film.

  Application methods

  Spray Use airless spray

  Brush Recommended for stripe coating and small areas, care must be taken to achieve the specified dry film thickness.

  Roller May be used for small areas but not recommended for first primer coat, however when using roller application care must be taken to apply sufficient material in order to achieve the specified dry film thickness.

  Application data

  Mixing ratio (volume) 4:1

  Mixing 4 parts Comp. A (base) to be mixed thoroughly with 1 part Balloxy BT, Comp. B (curing agent).

  Induction time 10 minutes.

  Pot life (23°C) 1.5 hours (reduced at higher temperatures).

  Thinner/Cleaner Jotun Thinner No. 17

  Guiding data airless spray

  Pressure at nozzle 15 MPa (150 kp/cm², 2100 psi)

  Nozzle tip 0.43-0.79 mm (0.017-0.031")

  Spray angle 40-80°

  Filter Check to ensure that filters are clean.

  Drying time

  Drying times are generally related to air circulation, temperature, film thickness and number of coats, and will be affected correspondingly. The figures given in the table are typical with:

• Good ventilation (Outdoor exposure or free circulation of air)

• Typical film thickness

• One coat on top of inert substrate

1. The earliest time for exposure to mechanical strain, i.e. to walk on the coated surface.

2. The earliest time for recoating with the same generic type of paint. Note that the paint film is not hard at this time and can not withstand mechanical strain.

1. Overcoating by itself for severe (mechanical or immersed) exposure.

The given data must be considered as guidelines only. The actual drying time/times before recoating may be shorter or longer, depending on film thickness, ventilation, humidity, underlying paint system, requirement for early handling and mechanical strength etc. A complete system can be described on a system sheet, where all parameters and special conditions could be included.

Other systems may be specified, depending on area of use

Storage

The product must be stored in accordance with national regulations. Storage conditions are to keep the containers in a dry, cool, well ventilated space and away from source of heat and ignition. Containers must be kept tightly closed.

Handling

Handle with care. Stir well before use.

Packing size
