Description
Product Features & Applications
Vinylester is a specially formulated grade Vinyl ester plain with excellent resistance to a wide range of corrosive chemical environments at room and elevated temperature. It is non-promoted, non-thixotropic type and formulated chemical-resistant unsaturated polyester resin based on selective epoxy and meth-acrylic acid processed carefully to specific molecular weight, dissolved in Styrene monomer in the presence of a specially chosen inhibitor for storage life of over months @ room temperature. The VER is resistant to a wide range of chemicals/fluid for exposure & application. The resin is especially suitable for filament winding and lay-up/spray-up, pultrusion pipelines, chemical process equipment, like Reactors, Blowers, and fume extraction equipment is resistant to a wide range of chemicals/fluid for exposure & application.
Typical Application:
- For fabrication of Bridge Support, ladder, etc. exposed to stringent, sewerage & effluents.

Usage & Post Curing:
- The Vinyl Ester performs best if the laminate is completely post-cured. The quantity of catalyst and accelerator can be adjusted to get a shorter or longer gel time.
- It is recommended to mature the products for 24 hours and post-curing should be done for a minimum of six hours at 80°C. This is recommended for getting the optimum properties.
