About this product
SPR 201 CC is the clear casting grade of the orthophthalic (SPR 201) polyester family. The supplier lists it for statues and idols, decorative articles and artefacts, and furniture top coats.
It is a different product from the Clear Casting Resin already in this catalogue, which is a two-part epoxy system. The two are not interchangeable: this grade is an unsaturated polyester cured with MEKP and cobalt octoate, while the epoxy is cured with its own hardener.
Samrat FRP Traders handles enquiries for this Samrat Poly Resins, India grade in Nepal. Pricing, packaging and availability are confirmed on enquiry.
What this means for buyers
Polyester, not epoxy
If your process was set up for the two-part epoxy Clear Casting Resin, do not substitute this grade without a trial. The chemistry, cure system and handling are different.
Same base as GP Clear
The catalogue gives this grade the same typical specification as SPR 201 GPC GP Clear Resin. The difference is the casting role it is supplied for.

How to read these values
- These are typical values from the supplier’s product catalogue. They describe the grade; they are not batch guarantees or acceptance limits.
- Resin data does not guarantee the performance of a finished FRP component. Confirm suitability with a trial on your own process, reinforcement and cure conditions.
Applications and processes
Uses listed in the supplier’s catalogue.
- Statues and idols
- Decorative articles and artefacts
- Furniture top coats
Limitations
- It is a polyester casting grade. Casting depth, clarity over time and yellowing in a particular piece are not published, and it is not interchangeable with the epoxy Clear Casting Resin.
- The values shown are typical catalogue values for the grade, not batch guarantees, acceptance limits or a Technical Data Sheet. Confirm the current data before relying on a figure.
- Resin data does not describe a finished part. Strength, durability, fire behaviour and chemical resistance of a part depend on its design, reinforcement, process, cure and testing.
When to consider a different resin
These grades are made for a different situation. Match them against your own service conditions.
- Clear Casting Resin (epoxy)The project is specified for an epoxy casting system rather than a polyester one.
- GP Clear ResinThe work is general-purpose FRP with no special service condition.

Sources: the 2026 product catalogue of Samrat Poly Resins, India for the catalogue grades, and each earlier product’s published Technical Data Sheet summary. Values are typical and were measured under the conditions each source states, so they are a guide to selection, not batch guarantees. Viscosities measured at different spindle speeds or shear conditions are not directly comparable.
Manufacturing and quality context
Samrat Poly Resins manufactures the grade in Doraha, Punjab, India. Its 2026 catalogue presents every grade under its resin chemistry and code and describes a quality inspection laboratory at Doraha. Batch-specific questions, gel-time or viscosity queries and clarification of catalogue values are answered by the manufacturer’s technical team.
The catalogue recommends a trial on the customer’s own process and reinforcement before commercial use: typical values are not a substitute for a trial. Technical and safety data sheets are issued grade by grade: this grade’s Technical Data Sheet is published on this page, and a Safety Data Sheet has not been issued for it here. Ask for the current revision before relying on a document.
Samrat FRP Traders supplies and imports the grade for Nepal and handles enquiries. It does not manufacture, reformulate or certify resins.
Handling and safety
- Use suitable personal protective equipment and adequate ventilation.
- Store resin, initiators and accelerators separately, in original sealed containers, cool, shaded and away from heat and ignition sources.
- Add the initiator and the accelerator to the resin separately, according to the confirmed process.
- Never mix a concentrated peroxide initiator directly with a cobalt accelerator.
