The anti-corrosive plastic coating is made of 11 polymiade
in HIGHLY VISIBLE YELLOW, and its technical features are as follows:
- Approximate thickness: 250 to 300 microns.
- Melting point: 184 to 186º C.
- Flammability: Self-extinguishable.
- Shore hardness D to 20º C, 75.
Overall, the coating is considerably resistant against bases, sea water and saline
environments: against oils, greasae and aromatic solvents: to organic acids, diluted
mineral acids and aliphatic solvents.
Neither fungi nor micro-organisms stick to the parts, nor does
frost collect on its surface.
Resistance to boiling water:
Excellent adhesion after 2000 hours.
Resistance to exposure to the element:
Excellent.
Resistance to salt spray:
There is no corrosion after 2000 hours exposure (ASTM B-117 or AFNOR X 41-002
standard).
Resistance to sea water:
There is no corrosion after 10 years exposure.
APPLICATION METHOD:
The previously prepared metallic part is heated ina n oven at a constant temperature
ranging between 300º C and 450º C, depending on the part mass and the
nature of the metal, and as soon as it is removed from the oven, it is placed
for three or four seconds in the powder suspended in a fluidification container.
When the powder comes into contact with the hot metallic surface it melts and
coats the said metal part evenly depending on the temperature of the part, its
thermal inertia and the duration of the immersion. The part is removed from the
container and air-cooled. |
