Superior Vinyl Ester Resin Properties

The vinyl groups refer to these ester substituents which are prone to polymerize.

Superior vinyl ester resin properties. 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. The diester product is then dissolved in a reactive solvent such as styrene to approximately 35 45 percent content by weight. 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. Advances in fire retardant materials 2008. However when crosslinked vinyl esters are noticeably stronger and tougher than conventional 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.

Flame retardant applications where translucency is required. The resin properties and formulation are similar to derakane 470 36. 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. 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.

However these are relative and other resins or composites may be superior and more expensive. Vinyl ester resins offer increased strength corrosion resistance and durability and are used in a wide variety of applications.
