Versatile rust preventive weldable primer – Bloxide, protects plate edges for a year.


A reputed Indian Fabricator company, makes large tanks, for storage of petroleum and petrochemicals. Plate for the tanks comes cut to size from their fabrication shop and shipped to the field site for assembly, the plate is welded by 7018 SMA electrode or GMAW.

Without the use of versatile rust preventive weldable primer, the unprotected plate edges rust quickly making for trouble during welding. Rusted plate edges need cleanup in the field, costly and time-consuming work. Supertech introduced a wonderful brush-on primer that prevents rust. The primer is an alumnized paint. It dries fast, forming a tenacious oxygen barrier film in minutes. Bloxide, made by the La-Co Industries Inc, (Formerly Tempil).

It does not interfere with welding and, in fact, serves as an anti-spatter agent. It also forms a foundation for other paints that protect against moisture and corrosion at atmospheric and high temperatures.

Back at the fabrication shop the workers remove oil and grease from plate edges, then brush on the primer. Once it dries, the plate edges will not rust even when stored outdoors for as long as 12 months. There is no requirement of buffing or grinding plate edges before field welding; and it doesn’t interfere with welding.


Bloxide can be advantageously used on all steels, and Is compatible with most welding processes

Stop rust with Bloxide :

Bloxide is a weldable rust preventive that insures x-ray quality welds. The aluminized coating acts as an oxygen barrier that protects against rust. It also forms aluminum oxide in the weld puddle which reduces porosity and pinholing.

The use of Bloxide eliminates recleaning of sub assemblies prepared for welding even after they have been in outside storage for several months. It is an excellent weldable primer paint, and leaves no objectional residue or slag. Bloxide is free of lead, sulfur, zinc, cadmium, mercury, chlorine or other halogens which make it safe for the nuclear fabrication industry

How to Use Bloxide:

It is available in 1 gallon (3.78ltrs) packing. It can be applied by brushing, spraying or dipping. It requires no special training, equipment, or precautions for effective application. Bloxlde is quick drying, forming a tack-free, tenacious film in minutes.

Typical applications:

Bloxide can be advantageously used on all steels, and Is compatible with most welding processes. It should definitely be evaluated when x-ray quality welding is required.
