Unsaturated Polyester Resin
Unsaturated Polyester Resins are manufactured by condensation reaction between acids like Isophthalic Acid, Phthalic Anhydride, Maleic Anhydride and glycols like Propylene Glycol, Di-ethylene Glycol, Mono-ethylene Glycol, etc. at temperature 210 - 230°C in stainless steel reactor under nitrogen atmosphere. During reaction water is formed which is regularly removed in order to remove traces of un-reacted glycols & water. Vacuum is applied. Once the desired parameters are achieved, the product is cooled and transferred to blender having Styrene Monomer with stirring on. Temperature in blender is not more than 60 - 65°C. After achieving all parameters of resin i.e. acid value, gel time, viscosity, etc.; resins are transferred in barrels.
We are one of the leading manufacturers of Unsaturated Polyester Resin in India and supply to all leading FRP moulders. Our plant is about 100km from Mumbai at Wada. It is a well-equipped, modern plant operated by well qualified & trained staff along with Quality Control laboratory and R&D department. In our factory, all incoming raw materials as well as finished products are tested on regular basis. Thus, maintaining batch to batch consistency. We are ISO 9000 certified company.
We manufacture all grades of unsaturated polyester resins like Isophthalic resin, Vinyl Ester resin, Boat grade resin, Fire Extinguishing resin & General Purpose resins and their gel-coats. We can offer resin as per customer requirement. Our ultimate motto is customer satisfaction.
