Anticorrosive primer composed of high molecular weight epoxy resins and polyamides as well as a pigment system based on anticorrosive pigments and fillers with low chemical inertia. It stands out for its mechanical characteristics and excellent resistance to corrosion and salt spray.
Modo de empleo :
It must be applied at temperatures above 4ºC and always above the dew point.
For its use, the two components must be mixed in a 4:1 ratio by weight, preferably mechanically, failing which a perfect homogenization of the mixture will be ensured. To achieve this proportion, the total content of component B must be poured over component A. Once the mixture has been made, it must be applied within the following 20 hours. The interval between coats, whether they are of the same primer or with finishing paints, should not exceed 20 hours in order to obtain good adhesion between them.
It can be applied by brush, roller or spray, diluting in each case with “”Epoxy Diluent”” in proportions of 5, 10 and 15-20% respectively. Spray application provides the best results in terms of layer uniformity.
If the complete containers are not used and in order to obtain the best results, the quantities indicated in the characteristics section will be weighed; 4 parts of Comp. A with 1 part Comp. B by weight.
Non-observance of these standards can lead to finishes with an oily or sticky appearance.
Surface preparation:
The surfaces to be painted must be free of rust, dust, grease and remains of old paint. Special attention must be paid to the elimination of “”calamine”” (crystalline oxide from rolling or extrusion with a hard, smooth, shiny and bluish appearance) because over time it detaches from the support dragging the paint.
On surfaces with the presence of calamine, this will be removed by mechanical means, preferably by sandblasting grade SA 2 ½ . Red oxide (rust) can be removed by brushing, disc or hammering to ST3 grade.
It must be applied at temperatures above 5ºC and always above the dew point.
On iron surfaces; After cleaning and sanitizing them, between 1 and 3 coats of 40 microns of primer will be applied depending on the aggressiveness of the medium.
On light metals; Understand as such galvanized iron and alloys. After conditioning and cleaning it is necessary to apply a coat of Whash-primer with a maximum thickness of 10 microns in order to ensure good adhesion.
