Epoxy Vinyl Ester Coating

Standard epoxy vinyl ester resins are limited to 220 250 o f 104 121 o c in most applications.

Epoxy vinyl ester coating.

While many epoxy coatings perform best within typical climate controlled environments vinyl esters offer facilities more flexibility when it comes to room and surface temperatures. Due to its high molecular weight and low permeability it will withstand exposure to a broad range of acids caustics and solvents. Vinyl esters have enhanced mechanical properties compared to polyesters with physical strength better impact and thermal shock resistance. The coating system can achieve a dry film thickness of up to 1350 microns 54 mils in a single coat.

Vinyl ester resin is widely used in many industries due to its superior chemical resistance and low permeability. High density cross linked products are suitable for temperatures above 250 o f 121 o c. However most are prepared solely with reactive vinly type monmomers. Epoxy novolac and vinyl ester systems are two polymer technologies specially engineered as anti corrosive coating systems.

Conductive vinyl ester system pip ve conductive coating is a 10 15 mils thick epoxy novalac vinyl ester resin top coat system designed to facilitate electrostatic control while exhibiting excellent resistance to both aliphatic and aromatic organic and inorganic acids. They provide reduced viscosity and improved curing at low promoter levels for enhanced performance in filament winding operations while maintaining the mechanical properties and corrosion resistance. Bisphenol epoxy vinyl ester resin description the dion 9102 series are special versions of the dion 9100 of bisphenol epoxy vinyl ester resins. In some cases conventional solvents such as xylenes are also used.

Thermal stability in the face of a wider range of temperatures in addition to outstanding chemical resistance is one reason vinyl ester coatings are used to. Epoxy vinyl ester resins also find uses in coatings particulalry for the marine building and construction industries due to their excellent corrosion and weathering resistance. Often low odor high solids epoxy novolac coating and resurfacing systems offer superior resistance to acid and caustic exposures.
