Project Title:
VOC-Compliant Primerless Silicone
Coatings for Corrosion Control
Technical Abstract (Limit 200 words)
A VOC-compliant anticorrosion coating is proposed
for maintaining structural metals such as aluminum
and steel in corrosive field environments. The
proposed research explores the feasibililty of using
an aqueous dispersion of silicone resins stabilized
with novel polymeric surfactants and pigmented
with non-toxic anticorrosive additives to yield
coatings with excellent inherent adhesion to metals
and high corrosion inhibiting ability. The proposed
anticorrosion formulations, although waterborne,
would possess the ability to displace absorbed
water from the surfaces of poorly treated metallic
substrates and adhere strongly without the need for
pre-coat priming. The substitution of multi-function
polymeric surfactants for conventional surfactants
should significantly reduce the emissivity of the
resulting coatings. The interaction of the proposed
coating components and hydrated metal surfaces
will be computer simulated to optimize the unprimed
coating-substrate adhesion and barrier properties.
The VOC-compliant coatings would be tested
against conventional solventborne silicone coatings
for adhesion and corrosion inhibition. The ability to
form inherently adherent, durable barrier coatings
over poorly treated structural metal alloys without
the need for volatile organic solvents would
represent a signficant advancement in corrosion
engineering and aerospace maintenance
technology.
Potential Commercial Applications (Limit 200 words)
The benefits of a waterborne coating for improving
the corrosion resistance of structural metals include
reduced workplace health hazards, lower disposal
costs, greater system reliability, and improved
mission readiness. Potential commercial
applications lie in the manufacture and maintenance
of military, industrial and aerospace vehicles and
equipment.
