Three core technologies, each developed for its own set of processes and performance demands.

Orthophthalic, isophthalic and Iso-NPG polyester resin solutions for pipes, tanks, panels, marine and composite manufacturing.

High-performance vinyl ester solutions for demanding corrosion and chemical environments — tanks, scrubbers, ducts and pipes.

Pigmented, clear and specialty gelcoat solutions for high-quality surface finishing on moulded FRP parts.

Filament-wound GRP pipe for water, effluent and process lines.

Storage tanks and process vessels for water and chemicals.

Scrubbers, ducts and towers that resist corrosive media.

Translucent sheets, sandwich and cladding panels.

Hulls, decks and marine laminates.

Bathtubs, shower trays and wash basins.

Gratings, cable trays and structural profiles.

Covers, housings and automotive parts.

From chemical plants to rolling stock, our resins are specified where failure is not an option.
Components where weight, finish and repeatability matter.
Durable composite materials for structures and façades.
Resin systems for insulation and electrical parts.
Fire-safe composites for mass-transport programmes.
Laminating resins and gelcoats for boatbuilders.
Chlor-alkali, fertilizer, pulp & paper and wastewater plants.
Resins developed for F&B processing standards.
Optical-fibre coating resins for connected networks.
Process-tuned resins for OEMs and fabricators.


Crest is a resin manufacturer, not a trader. You work directly with the people who formulate, cook, test and document every batch — from first technical question to repeat container.



The same six disciplines behind every batch, whether you order one drum or a container.

Every incoming lot is tested before it reaches a reactor.
Recipes run to defined temperature and time profiles.
Acid value, viscosity and gel time tracked during the cook.
Each batch checked against its technical data sheet.
COA per batch, with retained samples for traceability.
Chemists help tune the resin to your process.

Resins leave our plants export-ready — packed for sea freight, shipped from India's two largest west-coast ports and documented for your customs.
Data sheets, safety data and batch certificates — shared with every quotation and shipment.

Three decades of resin development, applied to one goal: resin that behaves the same way in your shop, batch after batch.
Resin chemistry made in-house since 1989.
A chemist, not a call centre, answers your questions.
Batch testing and documentation on every order.
Export-ready packing, paperwork and logistics.
