About this product
SPR 301 OT is the oil-storage-tank grade of the isophthalic (SPR 301) family. The supplier describes it as an isophthalic grade with good electrical and heat-resistance properties, for the FRP lining of oil storage tanks, and also lists chemical-equipment manufacturing.
For organic-solvent storage, sewage and effluent service the family has a separate grade, SPR 301 OS. For general water and chemical service, the starting point is the general SPR 301 Isophthalic Polyester Resin.
Samrat FRP Traders handles enquiries for this Samrat Poly Resins, India grade in Nepal. Pricing, packaging and availability are confirmed on enquiry.

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.
- Chemical-resistance wording describes the grade’s intended service. It is not a universal compatibility chart; the specific chemical, concentration and temperature decide suitability.
- 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.
- FRP lining for oil-storage tanks
- Chemical-equipment manufacturing
Limitations
- Chemical-service wording is not a compatibility chart. The stored product, its concentration and temperature decide whether a lining is suitable.
- 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.
- Organic Solvent-Resistant Grade Resin (SPR 301 OS)Organic-solvent storage linings, sewage pipes and effluent equipment.
- Vinyl Ester ResinThe chemical service is more aggressive than a polyester lining is specified for.

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.
