Vinyl Ester Coating Vs Epoxy

Vinylester is essentially a styrene modified epoxy resin.

Vinyl ester coating vs epoxy.

Essentially they comprise a base of polyester resin strengthened with epoxy molecules in the backbone of the molecular chain. First you paint around the edges of the space with a bristle brush and then you fill in the rest with the roller. Specifically proper cure of vinyl ester resins and a 15 year study of the effective use of permeation barriers in marine composites to prevent corrosion and blistering. To cover wood a laminate using epoxy resin and 10 oz cloth will yield a much better job than 10 oz.

Vinylester resin as was explained to me by an r d chemist named mike daniels. Epoxy adheres to wood much better than polyester does. Applying epoxy coating in your garage is a manual process that requires an extended paint roller. Mike works for a huge minnesota company and he does know his chemistry.

It adds excellent strength rigidity adhesion water and chemical resistance. Cloth and polyester resin. Vinyl esters also use peroxides e g. Using epoxy you can improve the laminate properties with a post cure almost always.

Has some great papers on this which i am quoting from. While best known for their excellent ability to withstand chemical exposure depending on specific formulation many vinyl ester coatings also offer good resistance to changes in temperature.

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.

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. Epoxy for thermal stability. Vinyl ester resins are produced by the reaction esterification between an epoxy resin and an unsaturated monocarboxylic acid. The coating system can achieve a dry film thickness of up to 1350 microns 54 mils in a single coat.

Epoxy vapors can be powerful so always wear protective breathing gear such as a respirator with an acid filter.
