Abstract
Disclosed herein are epoxy-polysiloxane polymer coating compositions suitable for coating surfaces that provide excellent chemical, corrosion, or weather resistance. The epoxy-polysiloxane polymer coating compositions include polysiloxane and non-aromatic epoxide resins, and a cure system, wherein the combined composition reacts to form a cross-linked epoxy-polysiloxane polymer structure. The cure system can include at least a blend of metal or organic catalyst(s) and alkoxy functional aminosilane(s), and may further include a polyurethane, such as a silane terminated polyurethane. The metal catalyst may be coordinated with, or in close proximity to, the polyurethane, thus providing excellent hardening results at very low metal concentrations.
