Vinyl Ester Resin Bond Strength

When using vinyl ester resin be sure to use it quickly after purchasing.

Vinyl ester resin bond strength.

In terms of physical properties and cost vinylester resin is a compromise between low cost polyesters and epoxy resins. New generation mas epoxies have curing systems which are phenol free representing a safe step forward for all resin users. While vinyl ester resins are classified as polyester based formulations they are actually an intermediate between a polyester backbone and epoxy terminations on the ends of the molecules. Excellent secondary chemical bond to polyester laminate when making repairs or when strength and stiffness are important.

To achieve the highest bond strength and water resistance use lbi s 901 vinylester resin. Epoxy resin should be used. Highly water and chemical resistant. Vinyl ester has a shelf life of 3 months.

Vinyl esters also use peroxides e g. Generally in all categories of work the builder repairer will realize the greatest degree of bond strength waterproofing and toughness with well formulated epoxies. Essentially they comprise a base of polyester resin strengthened with epoxy molecules in the backbone of the molecular chain. Resin has a short shelf life.

An extremely high strength resin used for making strong stiff laminates. Its use is limited to the construction of high performance power boats where vinylesters increased bond strength has helped eliminate bonding problems with core materials vinylester resin is also used as a great water barrier when mixed properly with glass. When higher strength bond and water resistance is required such as keel rudder repair or out board transom replacement use lbi s 302 isothalic polyester resin. Call for specific applications.

An ideal choice for repairs to high stress areas such as rudders skeg and fin. Vinyl ester resins are the binary resin systems containing a dimethacrylate monomer from which the cured material gains most of its properties and a reactive monomer such as styrene which acts as a reactive diluent and also takes part in the cross linking reaction. Vinylester is essentially a styrene modified epoxy resin. Bond strength and bond slip relationships.

The styrene in the polyester or vinyl ester resin will melt it.
