Vinyl ester coating vs epoxy.

Mike works for a huge minnesota company and he does know his chemistry. Applying epoxy coating in your garage is a manual process that requires an extended paint roller. Vinylester resin as was explained to me by an r d chemist named mike daniels. To cover wood a laminate using epoxy resin and 10 oz cloth will yield a much better job than 10 oz.

Here s a different way to look at epoxy resin vs. First you paint around the edges of the space with a bristle brush and then you fill in the rest with the roller.

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. Vinylester is essentially a styrene modified epoxy resin. Plus he has 25 years of making all kinds of cool stuff and is an expert wood crafter. Has some great papers on this which i am quoting from.

Epoxy for thermal stability. Using epoxy you can improve the laminate properties with a post cure almost always. 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.

It adds excellent strength rigidity adhesion water and chemical resistance. The coating system can achieve a dry film thickness of up to 1350 microns 54 mils in a single coat. Essentially they comprise a base of polyester resin strengthened with epoxy molecules in the backbone of the molecular chain. Vinyl esters also use peroxides e g.

Epoxy adheres to wood much better than polyester does.
