Vinyl Ester Resin

Vinyl Ester Resin

Vinyl Ester resin is produced from the esterificated of an epoxy resin with a methacrylic acid, and the reacted product is then dissolved in styrene monomer. Vinyl ester resin have got both advantages of unsaturated polyester resin and epoxy resin, including excellence corrosion resistance of most acidic and alkali chemicals ; more strength and mechanical properties; superior operability and environmental durability. 

Medium viscosity

High reactivity

Excellent mechanical property

Excellent fire retardant property

Widely used in all kinds of fire retardant FRP products
