About this product
SPR 201 RL (UV) is the UV-stabilized member of the orthophthalic roof-light grades. The supplier lists it for UV-stabilized clear roof-light sheets, sunlight-exposed translucent roofing panels and industrial daylighting.
It is a clear resin. This catalogue also carries UV Stabilized Sheet Grade Yellow Resin, a pre-pigmented yellow sheet grade; the two are different products. For roof-light sheet that is not exposed to sunlight, the catalogue points to SPR 201 RL Roof Light Resin.
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
Clear, not yellow
Order by code. SPR 201 RL (UV) is the clear UV-stabilized roof-light grade; UV Stabilized Sheet Grade Yellow Resin is a separate, pre-pigmented product.
UV-stabilized, not UV-curing
UV stabilization protects the cured sheet in sunlight. The resin is still cured with MEKP and cobalt octoate.

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.
- UV-stabilized clear roof-light sheets
- Sunlight-exposed translucent roofing panels
- Industrial daylighting applications
Limitations
- UV stabilisation is stated for the resin; no weathering life, light-transmission value or colour-retention period is published for a finished sheet.
- 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.
- Roof Light ResinThe sheets are standard roof-light sheets without a UV-stabilised requirement.

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.

Frequently asked questions
Is this the same as UV Stabilized Sheet Grade Yellow Resin?
No. This is a clear roof-light resin. The yellow sheet grade is pre-pigmented and is a separate product.
When should I choose RL (UV) over RL?
The catalogue’s selection guide points to RL (UV) where the roof-light sheet is exposed to sunlight, and RL for roof-light sheet otherwise.
Is a technical or safety data sheet available?
Yes. The supplier’s Technical Data Sheet for this grade is published on this page — Doc. Ref SPR-TDS-RLU, Rev. 01, September 2026, issued by Samrat Poly Resins, India. No Safety Data Sheet has been issued for this grade on this site; ask us and we will request the current one.
Is this the same as UV Stabilized Sheet Grade Yellow Resin?
No. SPR 201 RL (UV) is a clear roof-light grade; the sheet-grade yellow resins are separate products for coloured sheet work.
What does the catalogue list for viscosity and gel time?
200–400 cPs and 6.5–10 minutes, with 30–40% styrene; values are typical, not batch guarantees.
