An hydrophobic epoxy resin composition including at least one ortho-substituted glycidyl ether, at least one ortho, ortho'-disubstituted glycidyl ether, at least one ortho, meta&#x2032;-disubstituted glycidyl ether, at least one amine/aniline curing agent, and at least one organic solvent.

Curing agents for hydrophobic epoxy compositions

An epoxy-polysiloxane prepolymer composition(s) including, a mixture of polysiloxane oligomers having at least two epoxy groups, at least one monofunctional epoxy-siloxane as a reactive diluents, at least one amine, at least one pigment and/or at least one filler, at least one pigment dispersing agent, and at least one defoamer.

Polysiloxane based coating compositions

Super-hydrophobic epoxy resin compositions

The present invention provides a pigment/additive comprising discrete multivalent oxidation state (DiMVO) phenothiazine compounds having corrosion inhibiting properties. These novel DiMVO phenothiazines are useful in preparing waterborne primer coating formulations for application to metals and metal alloys and demonstrating corrosion inhibiting properties. Furthermore, such formulations are chromate-free and have reduced VOC content. Methods of preparing and using such compounds and waterborne formulations also are described.

Waterborne corrosion resistant organic primer compositions

A composite material composition that is simultaneously resistant to fire and galvanic corrosion; and, a method of manufacturing a composite material that has a fire resistant polycyuranate outermost barrier layer in composite structures.

Galvanic-corrosion-resistant composite material having a self-extingushing barrier layer

A composition and method of preparing and adding unique organic additives to a metal-free coating system followed by application then provides long term corrosion protection to a reactive metal surface.
