About this product
Samrat FRP Traders supplies and imports Unsaturated Polyester Resin (UPR) for the Nepal market. "Unsaturated Polyester Resin" is both the general chemical/commercial name for this resin class and, per current Samrat Poly Resins, India documentation, the generic commercial description under which one specific grade in this catalogue is also sold.
That grade is GP Clear Resin. Samrat Poly Resins' own product documentation confirms GP Clear Resin is supplied under both its branded name and the generic description "Unsaturated Polyester Resin" — the same formulation, same technical data sheet, ordered either way depending on how a buyer refers to it.
As a class, unsaturated polyester resins are liquid thermosetting resins dissolved in a reactive diluent (styrene), cured at room temperature with an MEKP catalyst and typically a cobalt accelerator. Orthophthalic UPR — the type Samrat Poly Resins publishes for GP Clear Resin — is the most common general-purpose grade used across FRP and composite manufacturing.
If you were quoted, or are searching, for "Unsaturated Polyester Resin" or "UPR" specifically, see the GP Clear Resin page for the full published technical data sheet, viscosity, gel time and styrene content. For a different UPR-family grade — lamination, white, quartz or button-grade — browse the other Polyester Resins in this catalogue. For current pricing, availability and packaging options in Nepal, contact Samrat FRP Traders through the enquiry page.
What this means for buyers
Same formulation, two names
Samrat Poly Resins' documentation confirms this generic description and the GP Clear Resin brand name refer to the same base formulation — buyers can order under either name and receive the same product.
Comparing UPR grades
"UPR" is also a family term. Lamination Resin, GP White Resin, GP Quartz Resin, Button Grade Resin and GP Yellow Resin are all unsaturated polyester resins in this catalogue with their own supplier documentation — compare grades before ordering if your project needs something other than the general-purpose grade.
Where the technical data lives
Full published technical values — viscosity, gel time, styrene content, cure time — are listed on the GP Clear Resin page, since that is the specific grade this generic description corresponds to.

Frequently asked questions
What is Unsaturated Polyester Resin (UPR)?
Unsaturated Polyester Resin (UPR) is a general-purpose liquid thermosetting resin used across FRP and composite manufacturing, cured at room temperature with an MEKP catalyst. It is both the broad resin-family term and, per Samrat Poly Resins' documentation, the generic commercial description for its GP Clear Resin grade.
Is Unsaturated Polyester Resin the same as GP Clear Resin?
For the grade Samrat Poly Resins supplies through Samrat FRP Traders, yes — supplier documentation confirms GP Clear Resin is the same formulation sold under the generic description "Unsaturated Polyester Resin." See the GP Clear Resin page for the full technical data sheet.
Why is it sold under two different names?
Some buyers order by the supplier's branded grade name (GP Clear Resin); others order using the generic commercial or chemical description (Unsaturated Polyester Resin, or UPR). Samrat Poly Resins documents both as referring to the same product.
Are all polyester resin grades in this catalogue the same as UPR?
Unsaturated polyester resin (UPR) is a family, not one single grade. Lamination Resin, GP White Resin, GP Quartz Resin, Button Grade Resin and GP Yellow Resin are all UPR-type resins with their own supplier data — GP Clear Resin is specifically the grade that corresponds to the generic "Unsaturated Polyester Resin" description.
Where can I find the technical data sheet?
Since this generic description corresponds to GP Clear Resin, its Technical Data Sheet (TDS) and Safety Data Sheet (SDS) are the same documents — available for download on this page or on the GP Clear Resin page.
