Superior Vinyl Ester Resin Properties

Ecmalon 9921 combines corrosion resistance with superior retention of properties at elevated temperatures.

Superior vinyl ester resin properties. Vinyl ester resin or often just vinyl ester is a resin produced by the esterification of an epoxy resin with acrylic or methacrylic acids. The diester product is then dissolved in a reactive solvent such as styrene to approximately 35 45 percent content by weight. However these are relative and other resins or composites may be superior and more expensive. The resin properties and formulation are similar to derakane 470 36.

Vinyl ester resins are easy to process and their physical properties in the uncured state are very similar to those of polyester resins. Best solvent resistance of any styrenated epoxy vinyl ester resin improved thermal properties. They also have superior stress fatigue and chemical resistance at both room and elevated temperature. Epoxy novolak vinyl esters are particularly recommended for use in chlor alkali industry.

If improved durability and impact resistance is important then vinyl esters win over polyesters and again the build can be tailored to use the vinyl esters in those areas with higher impact probability. Flame retardant applications where translucency is required. Advances in fire retardant materials 2008. 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.

Vinyl ester resins offer increased strength corrosion resistance and durability and are used in a wide variety of applications. However when crosslinked vinyl esters are noticeably stronger and tougher than conventional polyester resins.
