Orthophthalic unsaturated polyester resin; supplier-listed for general FRP work.
About this product
Samrat FRP Traders supplies and imports GP Yellow Resin for the Nepal market. Current Samrat Poly Resins, India documentation identifies GP Yellow Resin as a transparent yellow, orthophthalic unsaturated polyester resin — a general-purpose structural laminating resin, not a surface coating.
It shares the same MEKP and cobalt octoate cure system and hand layup / spray-up processing as the supplier's GP Clear Resin, but runs thicker and cures a little slower. The supplier documentation lists viscosity of 450–600 cPs against GP Clear Resin's 350–450 cPs, and a 10–15 minute gel time.
Published values also include 34–38% styrene content, 99% purity and a 60–90 minute cure time. The thicker body and slower cure can suit roofing sheets, water tanks, FRP doors and panels, and general lamination where the resin's own colour is hidden behind a gelcoat, paint or another layer.
Samrat FRP Traders can help Nepal buyers confirm whether GP Yellow Resin matches their 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 Yellow Resin is a general-purpose structural laminating resin with a transparent yellow tint. Where a colourless resin matters in the finished part, GP Clear Resin is the comparison point; the resin's own colour is less relevant when it sits behind a gelcoat or another layer.
Cure and handling
It shares GP Clear Resin's MEKP and cobalt octoate cure chemistry but is thicker (450–600 cPs) and cures slightly slower (10–15 minute gel, 60–90 minute cure). Adjust dosage to your workshop temperature.
Published values
Supplier documentation lists 450–600 cPs viscosity at 25°C, 10–15 minute gel time, 34–38% styrene content and 99% purity. These are processing data, not guarantees for a finished laminate.
Key features
- Transparent yellow orthophthalic base, sharing GP Clear Resin's cure chemistry
- Wets out glass fibre reinforcement for a consistent, well-bonded laminate
- Thicker body and slightly slower cure than GP Clear Resin (450–600 cPs, 10–15 minute gel)
- Cures at room temperature with the same MEKP and cobalt octoate system as GP Clear Resin
- 34–38% styrene content and 99% purity for consistent, batch-to-batch processing

Applications
Supplier documentation lists use in roofing sheets and daylighting panels, water tanks and storage vessels, FRP doors and decorative panels, and general lamination and FRP moulded products.
GP Yellow Resin for Water Tank ManufacturingWater tank panels need a resin that wets out glass reinforcement cleanly and cures into a strong, leak-resistant laminate — GP Yellow Resin's orthophthalic base and MEKP/cobalt cure suit this structural role wherever the tank's exterior is finished over the resin's natural yellow tint.
GP Yellow Resin for Cooling Tower ManufacturingCooling tower casings and internal components need a resin that cures reliably under sustained moisture — GP Yellow Resin uses the same MEKP and cobalt octoate cure system as GP Clear Resin, in a thicker, slightly slower-gelling grade suited to larger panel lay-ups.
GP Yellow Resin for Roofing Sheet ManufacturingGP Yellow Resin's transparent yellow, general-purpose orthophthalic base wets out reinforcement for corrugated FRP roofing sheets. For a factory-pigmented grade tuned specifically for sheet production instead, Sheet Grade Yellow Resin is the dedicated alternative.
GP Yellow Resin for Door Skin ManufacturingMoulded FRP door skins need a laminating resin that wets out reinforcement cleanly behind a gelcoat-finished face — GP Yellow Resin fills that structural role with the same cure chemistry as GP Clear Resin, in a thicker, slower-gelling grade.
GP Yellow Resin for Hand Lay-Up ProcessHand lay-up work relies on a resin that saturates chopped strand mat evenly, layer by layer — GP Yellow Resin uses the standard MEKP and cobalt octoate cure system, differing from GP Clear Resin mainly in its thicker body, slower gel and yellow tint.
GP Yellow Resin for Spray-Up ProcessSpray-up equipment chops and wets out fibre in a single pass, and GP Yellow Resin's viscosity and non-accelerated MEKP/cobalt cure make it workable through standard spray-up rigs — the same process route as GP Clear Resin, in a thicker, slower-gelling grade.
GP Yellow Resin for General FRP Moulded ProductsPanels, furniture, planters and general moulded FRP items need a dependable general-purpose laminating resin behind their surface finish — GP Yellow Resin serves this role wherever the part is painted, gelcoated or otherwise finished over its natural yellow tint.Industries served

Frequently asked questions
What is GP Yellow Resin?
GP Yellow Resin is a transparent yellow, orthophthalic unsaturated polyester resin. Current Samrat Poly Resins, India documentation lists it as a general-purpose structural laminating resin for roofing sheets, water tanks, FRP doors and panels, and general lamination.
What is the difference between GP Yellow Resin and GP Clear Resin?
Both are general-purpose orthophthalic resins with the same cure chemistry. GP Yellow Resin is thicker (450–600 cPs vs 350–450 cPs), gels and cures slower (10–15 minutes vs under 8 minutes), and carries a transparent yellow tint rather than being colourless.
Does GP Yellow Resin offer good chemical resistance?
As an orthophthalic polyester resin it offers standard-duty resistance for general FRP work. For moulds or parts facing harsher chemical exposure or continuous water immersion, a vinyl ester resin system is the more suitable choice.
What are the published viscosity, gel time and styrene content?
Supplier documentation lists 450–600 cPs viscosity at 25°C, a 10–15 minute gel time, 34–38% styrene content and a 60–90 minute cure time.
Is GP Yellow Resin the same as Sheet Grade Yellow Resin?
No. GP Yellow Resin is a general-purpose grade for broad FRP work, while Sheet Grade Yellow Resin is factory-pigmented and tuned specifically for FRP sheet and panel production.
