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.

SILBIONE PRIM 70073 may be stored for up to 18 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.Heavy Metals;RoHS
