What this industry manufactures
General FRP mould finishing covers the visible surface of decorative and industrial moulded products — wall panels, cladding, furniture panels, planters, signage, mannequins and other moulded décor and industrial items — wherever a smooth, glossy, coloured mould-facing finish is wanted rather than a raw laminate surface.
Why GP Gelcoat Resin is suitable
GP Gelcoat Resin's thixotropic body and high gloss finish suit the varied mould shapes this category covers, from flat panels to detailed decorative mouldings. As with every other gelcoat application, it is not the structural material of the part: glass fibre reinforcement wet out with GP Clear Resin is built up behind the gelcoat to form the actual structural laminate, sized to whatever the specific product needs. Because this category spans such varied products, required laminate thickness and reinforcement varies job to job — the gelcoat step itself stays the same throughout.
Required resin characteristics
- 01Good flow into varied mould shapes, from flat panels to detailed decorative mouldings
- 02High gloss, smooth cured finish across a wide range of product types
- 03Pigmentable for the colour range general moulded and décor products are commonly sold in
- 04Room-temperature MEKP cure compatible with standard mould workflows
Manufacturing process
Gelcoat is sprayed or brushed onto the mould first and left to gel, then glass fibre reinforcement wet out with GP Clear Resin, catalysed with an MEKP hardener and cobalt octoate accelerator, is built up behind it — with thickness and layer count adjusted to the specific product, from a lightweight decorative item to a structural panel. Once cured, the part is released from the mould with the gelcoat forming its finished surface, trimmed and finished as the product requires.

- Consistent MEKP/cobalt cure across varied production runs
Common products produced
- Decorative and cladding wall panels

Frequently asked questions
The gelcoat step itself is consistent — sprayed or brushed onto the mould first, then backed with a structural laminate. What varies job to job is the laminate thickness and reinforcement built up behind it, which is sized to whatever the specific product needs.
No. It is the cosmetic surface coating, applied to the mould first. The structural laminate — typically GP Clear Resin reinforced with glass fibre — is built up behind it separately.
Yes. GP Gelcoat Resin is supplied plain white, and FRP Polyester Pigment can be blended in before catalysing to match the colour range needed for panels, furniture or décor items.
Yes — its flow and thixotropic body support good coverage of detailed or textured mould surfaces, helping reproduce ornamental designs accurately in the cured finish.
It is cured at room temperature with an MEKP catalyst (around 1.5%) and a cobalt octoate accelerator (around 0.4%), the same system used across Samrat Poly Resins' gelcoat and general-purpose grades.
