Polyester surface-coating gelcoat for the mould-facing / outer-layer role.
About this product
Samrat FRP Traders supplies and imports GP Gelcoat Resin for the Nepal market. Current Samrat Poly Resins, India documentation identifies it as a polyester surface-coating gelcoat for the mould-facing, outer-layer role in FRP laminate systems.
A gelcoat is not a laminating resin. It is applied to the mould face first — brushed, sprayed or rollered — and forms the visible, protective outer skin of the finished part, while the structural laminate is built up behind it with a laminating resin and glass fibre reinforcement.
Supplier documentation describes the product as white, high-gloss and thixotropic, with a viscosity of about 11,000 cPs and a gel time of 8.5 minutes. The thixotropic behaviour is the practical point for buyers: it helps the gelcoat cling to vertical and overhead mould surfaces without sagging, and the supplier notes it can be pigmented with a polyester pigment for coloured finishes.
Technical specifications are published in the supplier's Technical Data Sheet, with a Safety Data Sheet also available. For current pricing, availability and packaging options in Nepal, contact Samrat FRP Traders through the enquiry page.
What this means for buyers
Gelcoat vs. laminating resin
Gelcoat is the surface coat, applied to the mould with no reinforcement mixed in; a laminating resin saturates the glass fibre behind it. The two roles are not interchangeable.
Thixotropic behaviour
The thixotropic character helps the gelcoat resist sagging on vertical and overhead mould surfaces, building an even coating. This is a practical property, not a guarantee of finish on every mould.
Colour and outdoor exposure
Supplied white and high-gloss, it can be blended with FRP Polyester Pigment for coloured finishes. For long-term outdoor colour stability, confirm UV-related requirements on enquiry.

Product details
Applications
Supplier documentation lists use on mould surfaces for FRP boat hulls and body panels, bathware and sanitaryware, water tank exteriors, and FRP furniture, panels and moulded components.
Gelcoat for Boat & Marine Hull FinishingBoat and marine hulls need a smooth, glossy cosmetic skin applied to the mould first — a surface coating, not the structural laminate that gives the hull its strength.
Gelcoat for FRP Bathware & SanitarywareBathtubs and shower trays need a smooth, glossy mould-facing surface coat applied before the structural laminate — the cosmetic finish, not the reinforced backing.
Gelcoat for Water Tank ExteriorsFRP water tank exteriors need a clean, glossy cosmetic surface coat applied to the mould face — separate from the structural laminate that forms the tank wall itself.
Gelcoat for General FRP Mould FinishingPanels, mouldings, furniture and décor items need a smooth, glossy mould-facing surface coat, applied before the structural laminate behind it — the cosmetic layer, not the structural resin.
Gelcoat for Automotive & Transport Body PanelsFRP body panels for buses, autorickshaws and trucks need a smooth, glossy cosmetic surface coat applied to the mould face — separate from the structural laminate built up behind it.Industries served

Frequently asked questions
What is GP Gelcoat Resin?
Supplier documentation identifies it as a white, high-gloss, thixotropic polyester surface-coating gelcoat for the mould-facing outer layer of FRP laminates. Samrat FRP Traders supplies and imports it for Nepal.
How is a gelcoat different from a laminating resin?
A gelcoat is applied to the mould face as the outer skin, with no reinforcement mixed in. A laminating resin saturates and binds the glass fibre reinforcement behind it. They are different roles in the same laminate.
What published technical values should I know?
Supplier documentation lists a viscosity of about 11,000 cPs and a gel time of 8.5 minutes, and describes the product as thixotropic. Confirm current values against the supplier TDS.
Why is it thixotropic?
Thixotropy helps the gelcoat cling to vertical and overhead mould surfaces and resist sagging before it gels, which supports an even coating thickness rather than pooling.
Can it be coloured?
Supplier documentation notes that a polyester pigment can be blended in for coloured finishes beyond the standard white. Confirm the shade and dosage before ordering.
