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.
