In one aspect, the heat-age stable compositions include an acrylic, styrene acrylic, vinyl acrylic copolymer or blends thereof including, as additional polymerizable units, at least one polymerizable phosphate surfactant and at least one linear or branched hydrophobic monomer that are both polymerized into the acrylic, styrene acrylic, vinyl acrylic copolymer backbone.

Sol-gel coating formulations including metal oxide particles such as aluminum oxide, calcium oxide, zinc oxide, magnesium oxide, and molybdenum oxide embedded in a hybrid polymer matrix based on a reacted form of a resin composition containing a tetraalkylorthosilicate, an aminoalkylsilane, a dialkoxysilane, and a silanol terminated polydimethylsiloxane. The sol-gel coating formulations are suitable for applications such as anticorrosive protective coatings of metal substrates (e.g. mild steel). These anticorrosive coated metal substrates are evaluated on their hydrophobicity (water contact angle), surface roughness, mechanical strength (e.g. hardness), adhesiveness to the substrate (e.g. critical load), and anticorrosiveness upon exposure to a saline solution (e.g. impedance value).
