Sheet Grade Yellow Resin is an orthophthalic unsaturated polyester resin supplied pre-pigmented yellow for the published FRP sheet and panel role. The current Technical Data Sheet lists it for sheet moulding and laminate applications, helping buyers separate a supplied-yellow sheet/panel requirement from a transparent-yellow general-purpose grade or a water-white roof-light resin. Review the intended sheet or panel, supplied appearance, reinforcement requirement, production context and current TDS before selecting a resin route. Samrat Poly Resins publishes 225 kg drum packaging for this product.

Sheet Grade Yellow Resin is typically catalysed with an MEKP hardener and reinforced with glass fibre during sheet lay-up or compression moulding. Where a project needs an unpigmented general-purpose grade instead, see our GP Clear Resin or base Unsaturated Polyester Resin (UPR); for door and plywood lamination work, our Lamination Resin is more suitable, and mould-facing sheets can be finished with a Gelcoat Resin or upgraded to Vinyl Ester Resin for higher chemical resistance.

What is Sheet Grade Yellow Resin?

Sheet Grade Yellow Resin is Samrat Poly Resins’ published pre-pigmented yellow orthophthalic unsaturated polyester resin for sheet moulding and laminate applications. Here, “sheet grade” identifies the intended sheet and panel manufacturing role, rather than a broad general-purpose resin search.

It is relevant when the FRP sheet or panel requirement calls for a supplied yellow resin route. The resin is one part of a wider material decision: review the intended sheet or panel, reinforcement, surface-finish requirement and current product-specific TDS. This does not make the grade a substitute for a water-white roof-light resin, a general-purpose GP Yellow Resin, a bonding-focused Lamination Resin or a mould-facing Gelcoat Resin.

Key features

Applications

  • FRP sheets and panels for industrial use
  • Decorative and coloured composite panels
  • Electrical enclosures and washroom partitions
  • Compression moulding and hand lay-up sheet production

What this means for sheet and panel buyers

Sheet/panel-specific product role

The current TDS publishes this grade for sheet moulding and laminate applications. Use it as the starting point for a specific FRP sheet or panel requirement, not as a catch-all GP resin selection.

Supplied appearance is a selection point

Confirm whether a pre-pigmented yellow supplied appearance suits the finished-product requirement. For a water-white resin intended for translucent roof-light panels, review the separate Roof Light Sheet Grade Resin route.

Define the full material requirement

Share the sheet or panel, reinforcement requirement if known, visible surface role, expected quantity and delivery location. Use the current TDS as the document for the product discussion.

Frequently asked questions

Sheet Grade Yellow Resin is an orthophthalic unsaturated polyester resin, factory-pigmented yellow, formulated for FRP sheet and panel manufacturing where consistent colour is required across every batch.

Factory pigmentation ensures uniform colour depth and consistency throughout the sheet, batch after batch — mixing pigment by hand at the mould is harder to control and can lead to visible colour variation between sheets.

They share the same base resin chemistry, but Sheet Grade Yellow Resin is factory-pigmented yellow for opaque, consistently-coloured FRP sheets and panels, while our Roof Light Sheet Grade Resin is left water-white for translucent roofing and skylight sheets. Choose based on whether you need an opaque coloured sheet or a light-transmitting roofing sheet.

No. Sheet Grade Yellow Resin is the published pre-pigmented yellow grade for sheet moulding and laminate applications. GP Yellow Resin is the separately published transparent-yellow, general-purpose orthophthalic grade. Start with the actual FRP sheet or panel role, supplied appearance and current product-specific TDS before choosing between them.

Share the intended FRP sheet or panel, required supplied yellow appearance, reinforcement requirement if known, production process or finished-product context, expected quantity and delivery location. This supports a focused product and commercial discussion without confirming suitability before review.

Review Glass Fiber Mat when reinforcement is part of the requirement. For a water-white roof-light or skylight sheet, review Roof Light Sheet Grade Resin; for a mould-facing surface role, review GP Gelcoat Resin. Each product has a separate published role and Technical Data Sheet.

Gel time is 6.5 minutes. Full cure at room temperature, once catalysed with MEKP (around 1.5%) and a cobalt octoate accelerator (around 0.4%), takes approximately 12 hours.

Viscosity is approximately 280 cPs and styrene content is 35%.

Shelf life is 2 months from manufacture. Store between 30–35 °C, away from direct heat and sunlight.

It is supplied in bulk 225 kg drums.

Choose the product role for the FRP sheet or panel

Sheet Grade Yellow Resin vs GP Yellow Resin

Sheet Grade Yellow Resin is the published pre-pigmented yellow route for sheet moulding and laminate applications. GP Yellow Resin is the separately published transparent-yellow general-purpose grade. Start with whether the requirement is specifically a sheet/panel role and whether the supplied appearance is appropriate.

Sheet Grade Yellow Resin vs Roof Light Sheet Grade Resin

Review this product where the supplied yellow sheet/panel route is relevant. Review Roof Light Sheet Grade Resin where the published requirement is a water-white resin for translucent roof-light or skylight panels. Confirm the intended finished appearance before selection.

Sheet Grade Yellow Resin vs GP Clear Resin

GP Clear Resin is the published clear general-purpose grade for broader FRP manufacturing. This Sheet Grade Yellow Resin is the more specific product route to review for a pre-pigmented yellow sheet or panel requirement.

Sheet/panel manufacture vs Lamination Resin

Sheet Grade Yellow Resin is published for sheet moulding and laminate applications. Lamination Resin is the separate product to review for its published door, plywood and FRP-bonding roles.

Structural sheet role vs Gelcoat Resin

Where a mould-facing surface layer is required, review GP Gelcoat Resin separately. It has a different product role from the reinforced laminate or sheet resin requirement.

When to review Vinyl Ester Resin

For a stated chemical- or corrosion-resistance requirement, review Vinyl Ester Resin and its product-specific TDS rather than assuming a general orthophthalic sheet-grade resin is appropriate.

Sheet grade within the UPR family

Unsaturated Polyester Resin is the parent category. This product is a specific yellow sheet/panel route within that broader family; the standard UPR data is not this grade’s specification.
