In order to limit the thickness of the film (2 - 3 microns is sufficient), SILBIONE PRIMER 70073 is diluted by half, by volume, using Isopropanol.
Diluted in this manner, it is then sprayed on surfaces which are clean, dry and dust free.
Drying at ambient temperature for 30 to 45 minutes, protected from dust, is necessary before applying the SILBIONE CAF or SILBIONE CAF DISPERSION coat. This can be carried out several hours later if the surface is protected from dust.

Avoid discharge into drains, water courses or onto the ground. Store in a cool, dry place with adequate ventilation. Keep away from incompatible materials, open flames, and high temperatures. Nitrogen blanketing of containers is required. Avoid contact with oxidizing agents. Suitable containers: Steel drums coated with epoxy-resin.Please consult the Safety Data Sheet of this product.Heavy Metals;RoHS
