Abstrakt
The protective coatings based on the silicate based binders prepared and filled
with standard pigments and fillers were hardened by the following methods:
physical procedure, zinc powder with isometric spherical particles, zinc powder
with lamellar particles, blocked polyisocyanate in an organic solvent, blocked
polyisocyanate in water dispersion, with condensed aluminum phosphate,
hydrated aluminum phosphate, and alkoxysilyl isocyanurate. With coatings, the
physical-mechanical property tests of the coats on steel or glass panels, as the
case may be (adhesion by the grid method, bending strengths, cupping stability,
shock resistance, and coating hardness) and corrosion resistance in a
condensation chamber and salt chamber with cycles tests were performed. The
results obtained were evaluated from the silicate binder type point of view, as well
as the used hardening system type point of view. The overall best results were
obtained with a lithium-sodium water glass, the coats of which exhibit good
physicomechanical and anticorrosion properties. From the composition point of
view, the coating materials filled with zinc powder exhibit very good results. Zinc
with lamellar particle shape exhibits a higher anticorrosion efficiency.
