Bisphenol Fumarate Resin is manufactured by reacting Bisphenol-A with Propylene Oxide and Fumaric acid. It is a medium viscosity and high molecular weight Polyester Resin. It is particularly designed for Alkaline environments even at elavated temperatures. It is also resistant to acidic and selected solvent environments It contains very few ester linkages in its molecular chain. These ester linkages are protected by bulky groups. Hence FRP components fabricated with it have out standing corrosion resistance and hydrolytic stability to a variety of chemicals at ambient and at elavated temperatures.
It is a standard General purpose VINYL ESTER resin based on epoxy back bone. It is a medium viscosity resin offering extremely good resistance combined with low shrinkage, high temperature properties, good
adhesion to substrates and a high tensile elongation. It also combines the excellent mechanical and chemical properties of epoxy resins and the ease of processing of Polyester Resins.
Vinyl ester resin is recommended for the manufacture of FRP by Hand lay up, Spray up, Filament winding, Centrifugal casting, Bag moulding and Pultrusion. FRP structures and equipments fabricated from Vinylester resin provide a number of advantages over those made with conventional materials of construction.
- Outstanding corrosion resistance to many different chemicals including both acid and alkalies at room temperatures and elevated temparature
- Fast green strength
- Superior creep resistance
- High impact resistance
- High fatigue resistance
- High strength at low weight
- Excellent electrical and thermal insulation properties
