Samrat Poly Resins’ published standard clear orthophthalic unsaturated polyester resin (UPR) grade — also supplied under the generic commercial description "Unsaturated Polyester Resin."
About this product
Samrat FRP Traders supplies and imports GP Clear Resin for the Nepal market. Current Samrat Poly Resins, India documentation identifies GP Clear Resin as its published standard clear orthophthalic unsaturated polyester resin grade for everyday FRP and composite manufacturing.
Unsaturated polyester resin (UPR) is the broader resin family, and GP Clear Resin is Samrat Poly Resins' standard grade within it. For buyers specifically searching for "Unsaturated Polyester Resin" or "UPR", Samrat Poly Resins' own product documentation confirms GP Clear Resin is supplied as exactly that formulation — sold under both the branded name GP Clear Resin and the generic commercial description Unsaturated Polyester Resin, for customers who order it either way.
It is supplied as a non-accelerated liquid, which means the workshop doses an MEKP catalyst and a cobalt octoate accelerator to suit its own conditions, then cures at room temperature.
The supplier documentation lists a clear liquid appearance, viscosity of 350–450 cPs, a gel time under 8 minutes, 33–40% styrene content, 99% purity and a cure time of 45 minutes to 1.5 hours. Lower viscosity generally helps the resin wet out glass fibre reinforcement quickly, which is useful across hand layup, spray-up, moulding and lamination.
Samrat FRP Traders can help Nepal buyers confirm whether GP Clear Resin fits their water tank, roofing, sanitaryware, panel or general FRP project. For current pricing, availability and packaging options in Nepal, contact Samrat FRP Traders through the enquiry page.
What this means for buyers
Grade selection
GP Clear Resin is the broad general-purpose clear grade. If your work is lamination-focused, review the Lamination Resin grade; where a white-pigmented resin on the same base specification is wanted, GP White Resin is the comparison point.
Curing system
It is non-accelerated, so the MEKP catalyst and cobalt accelerator are dosed at the workshop to match temperature and batch size. Follow the supplier TDS dosage and run a small trial before scaling up.
Published values
Supplier documentation lists 350–450 cPs viscosity, under 8 minutes gel time, 33–40% styrene content, 99% purity and 45-minute to 1.5-hour cure. These are processing data, not guarantees for a finished part.
Also sold as Unsaturated Polyester Resin
Samrat Poly Resins' documentation confirms GP Clear Resin is the same formulation sold generically as "Unsaturated Polyester Resin" (UPR). If you were quoted, or are searching, for UPR specifically, this is the matching grade.

Applications
Supplier documentation lists use in hand layup and spray-up laminates, FRP water tanks, roofing sheets, sanitaryware, panels, moulding, cooling-tower components and general-purpose composite products.
Resin for Water Tank ManufacturingWater tank manufacturers need a resin that wets out glass reinforcement cleanly and cures into a strong, leak-resistant laminate for long-term structural integrity.
Resin for Cooling Tower ManufacturingCooling tower components face constant moisture and temperature cycling, demanding a laminate with lasting mechanical strength and chemical resistance.
Resin for Roofing Sheet ManufacturingRoofing and cladding sheet manufacturers need even lamination across large panel areas, without pooling or dry patches that weaken the sheet.
Resin for FRP Door ManufacturingFRP doors need a laminate that bonds well to the door-skin substrate and holds its shape and strength through years of daily use.
Resin for Door Skin ManufacturingDoor skin production calls for excellent wet-out and a clean, glass-like cured finish straight out of the mould.
Resin for FRP Panel ManufacturingGeneral FRP panels — from partitions to enclosures — need a resin that processes predictably at volume, batch after batch.
Resin for Hand Lay-Up ProcessHand lay-up is the most common FRP fabrication method, and it depends on a resin that wets out reinforcement by hand without dragging or pooling.
Resin for Spray-Up ProcessSpray-up production needs a resin that atomises cleanly through spray equipment and gels on a predictable schedule.
Resin for Boat & Marine ComponentsMarine and boat components need proven wet-out over glass fibre reinforcement and reliable strength once the laminate cures.
Resin for General FRP LaminationWhatever the lamination job, fabricators need one resin whose viscosity, gel time and strength stay consistent across varied work.
Resin for General FRP Moulded ProductsFrom tanks to novelty mouldings, general FRP moulded products need a laminate that cures reliably and releases cleanly from the mould.Industries served
- FRP & composites manufacturing
- Water tanks & storage
- Construction, roofing & panels
- Sanitaryware & bathware moulding
- Cooling towers & industrial FRP
- General moulding & fabrication

Frequently asked questions
Is GP Clear Resin the same as Unsaturated Polyester Resin (UPR)?
Yes. Samrat Poly Resins' documentation confirms GP Clear Resin is the same base formulation supplied under the generic commercial description "Unsaturated Polyester Resin." Some customers order it under the GP Clear Resin brand name, others as generic UPR — both refer to the same product.
What is GP Clear Resin?
GP Clear Resin is a clear orthophthalic unsaturated polyester resin. Current Samrat Poly Resins, India documentation identifies it as its published standard general-purpose grade for hand layup, spray-up, moulding and lamination. Samrat FRP Traders supplies and imports it for Nepal.
Is it an orthophthalic or isophthalic resin?
It is an orthophthalic unsaturated polyester resin, formulated for general-purpose composite work where balanced mechanical performance and cost-efficiency are the priority.
What are the published viscosity, gel time and styrene content?
Supplier documentation lists viscosity of 350–450 cPs, a gel time under 8 minutes, 33–40% styrene content, 99% purity and a cure time of 45 minutes to 1.5 hours.
How is it cured?
As a non-accelerated resin, it is cured at room temperature by dosing an MEKP catalyst and a cobalt octoate accelerator. Dosage follows the supplier TDS and is adjusted to workshop conditions.
What is the difference between GP Clear Resin and Lamination Resin?
GP Clear Resin is a broad general-purpose grade for hand layup, spray-up and moulding, while Lamination Resin is tuned for door, plywood and FRP bonding. For lamination-focused projects, evaluate the Lamination Resin grade.
