Is epoxy a kind of vinyl polyester.

Unlike epoxy resin polyester and vinyl ester cure time can be manipulated by the amounts of mekp added. They are used for gluing fiber glassing moisture sealing and coating or encapsulating. That makes epoxy resin usually the best choice for fiberglass repair work. If it is not then poor curing and adhesion may result.

The majority of commercial vinyl polyester resins are derived from bisphenol a diglycidyl ether dgeba as the epoxy component and acrylic or methacrylic acid as the vinyl monomer in the polymer. As a general rule the tensile strength of a polyester bond will be around 20 percent weaker than the same bond made with epoxy. As with many products the surface must be prepared properly. A resin such as epoxy polyester or vinyl ester.

The applying procedure involves the preparing of the mixture preparing of the surface the applying and curing of the mixture and the final cleaning. Epoxy vinyl ester and polyester resins. There are three main types of boat building resins. As jeff wright wrote in polyester over epoxy in epoxyworks 22.

The less mekp added the longer the pot life working time will be. Always use the exact amounts of hardener or catalyst specified by the manufacturer or the resin will not cure properly. We know polyester gelcoat can be used over west system epoxy. Like polyester resins they require mekp as a catalyst to cure or harden.

Polyester is an adequate adhesive but not as good as epoxy. Many high strain repair areas and lightweight parts must flex and strain without micro fracturing. Typically catalyst is used between 1 25 to 1 75 1 2 3 ounce to 2 1 3 ounces per gallon. These are cheaper than epoxy resins and more expensive than polyester.

Due to the type of material and ease of distribution the polyester stickers can be used as a cost effective solution when choosing adhesives for promos or campaigns in order to make a big impact.

Vinyl ester resins are formulated with a base of polyester resin strengthened with epoxy molecules a hybrid form of polyester and epoxy and aiding for gelcoat to bond with epoxy and also use peroxides such as mekp for hardening. A hardener for epoxy or catalyst for polyester vinyl ester for activating the resin and ensuring that it eventually cures to a hard plastic material. Vinyl ester falls between polyester and epoxy on price most physical properties and handling qualities. There are a couple of exceptions.
