Superior Vinyl Ester Resin Properties

The diester product is then dissolved in a reactive solvent such as styrene to approximately 35 45 percent content by weight.

Superior vinyl ester resin properties.

Flame retardant applications where translucency is required. Epoxy novolak vinyl esters are particularly recommended for use in chlor alkali industry. 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. They also have superior stress fatigue and chemical resistance at both room and elevated temperature.

The vinyl groups refer to these ester substituents which are prone to polymerize. Ecmalon 9921 combines corrosion resistance with superior retention of properties at elevated temperatures. Advances in fire retardant materials 2008. The resin properties and formulation are similar to derakane 470 36.

Vinyl ester resin or often just vinyl ester is a resin produced by the esterification of an epoxy resin with acrylic or methacrylic acids. Best solvent resistance of any styrenated epoxy vinyl ester resin improved thermal properties. However these are relative and other resins or composites may be superior and more expensive. Use for equipment requiring superior corrosion resistance and thermal properties to standard flame retardant epoxy vinyl ester resins.

Vinyl ester resins are easy to process and their physical properties in the uncured state are very similar to those of polyester resins. 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.
