  • Provide maximum protection to steel surfaces
  • Used in all kind of industries
  • Prevents corrosion and rusting

DESCRIPTION
PRIMAX BOILER COMPOUND NO. 1 is Bituminous vehicle containing amorphous carbon pigment.

USES
A unique, specially formulated composition designed as an anti-corrosive coating for metal surfaces in continuous contact with hot water and steam above 93°C (200°F). It is particularly suited for the internal lining of steel boilers, steam pipes and hot well tanks. A regular maintenance schedule during shut down periods is necessary to ensure the log term performance of the coating. The product has been demonstrated to improve the heat transmission efficiency of coated surfaces, with real energy saving benefits.

Surface preparation
Remove grease, oil and other contaminants. Special care must be taken on weld areas to remove flux and spatter. Welds and joints should be prepared by grinding in accordance with EN 15879-1. Blast clean to a minimum standard of cleanliness Sa 2 1/2 BS 7079: 1989 (ISO 8501-\: 1988). Surface profile Rz should not exceed 100 microns (0.004 in.). If blasting is not practical, make full use of mechanical tools, manual chipping and wire brushing to remove rust and scale to achieve preparation standard St 2 BS 7079: 1989 (ISO 850I-I: 1988). Excessive burnishing of the steel should be avoided. Remove all dust and debris from the surface, which should be coated before contamination can occur. Existing Boiler paint No.1 coated surfaces should be clean, dry and free from dirt, oil, grease, scale or other contamination..

Application methods
Primax Boiler Compound No.1 should only be applied to clean metal or sound previous coats of itself. Three or more coats are required for full protection of steel, and at least two coats for the maintenance painting of surfaces previously coated with the product. Stir thoroughly before use, addition of thinner is not normally necessary.
Brush
This product is intended for brush application only, a minimum of two coats should be applied. Work the first coat well into the seams, bolts, etc. Since drying primarily occurs by solvent evaporation, good ventilation must be provided.
Surfaces coated with Primax Boiler Compound No.1 should not be exposed to weathering. Do not apply when relative humidity exceeds 90% and condensation is likely. Drying will be retarded below 4°C and painting should be stopped until temperature rises. Only apply coating when metal temperature is 3°C or more above dew point. When conditions approach these critical limits the use of heating and dehumidification equipment is essential if application is to continue. Loss factors based on the nature of the surface and the chosen application method should be applied to obtain a practical covering capacity.
Do not vary recommended dry film thickness without written confirmation.
Drying time
Drying times are generally related to air circulation, temperature, film thickness and number of coats, will be affected correspondingly.
* Good ventilation (Outdoor exposure or free circulation of air)
* Typical film thickness
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.
