Epoxy Vinyl Ester Coating
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.
Epoxy vinyl ester coating. However most are prepared solely with reactive vinly type monmomers. 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. High density cross linked products are suitable for temperatures above 250 o f 121 o c. Standard epoxy vinyl ester resins are limited to 220 250 o f 104 121 o c in most applications.
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. Often low odor high solids epoxy novolac coating and resurfacing systems offer superior resistance to acid and caustic exposures. Vinyl esters have enhanced mechanical properties compared to polyesters with physical strength better impact and thermal shock resistance. 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.
Ceilcote 242hb flakelineis a glass flake filled vinyl ester high build lining for use on steel and concrete substrates ceilcote 242hb flakelinehas excellent resistance to organic and inorganic acid solutions and many aliphatic solvents. Epoxy novolac and vinyl ester systems are two polymer technologies specially engineered as anti corrosive coating systems. Due to its high molecular weight and low permeability it will withstand exposure to a broad range of acids caustics and solvents. 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.
Vinyl ester resin is widely used in many industries due to its superior chemical resistance and low permeability. 100 solids vinyl ester provides superior solvent resistance in both primary and secondary containment areas. In some cases conventional solvents such as xylenes are also used.
