Surface, Repair & Finishing
2 guidesManufacturing Polyester Putty and Filler ProductsMaking the filler, not using it. What a putty base resin contributes to a formulated two-part product, and what the buyer of the resin is actually deciding.FRP Repair and Reinforcement with EpoxyBonding new laminate to something already cured is the job polyester is worst at. Why epoxy is reached for, and the one pairing question that has to be settled first.
Fire-Performance FRP
4 guidesFire-Retardant FRP Panels, Cladding and EnclosuresA fire-retardant resin is a formulation, not a rating. What that distinction means for a specification, and what evidence a project will actually ask for.FRP for Corrosive Service With a Fire RequirementSome equipment has to resist chemicals and meet a fire requirement at the same time. Why that combination has its own grade, and what to establish before specifying it.Halogen-Free Fire-Retardant Resin for FRP LaminatesLaminating FRP parts where the project specifies halogen-free fire retardancy, with SPR 201 FR (HF), and how it sits beside the isophthalic halogen-free and the halogenated fire-retardant resins.Fire-Retardant Gelcoat for Rail, Transport and Automotive FRP SurfacesThe mould-face surface of fire-retardant FRP parts, with the orthophthalic SPR 201 FR-GC and the terephthalic SPR 401 FRGC gelcoats, their different cure references, and how to pair them with the laminate.
Cast Stone, Moulding & Small Components
4 guidesCultured Marble and Artificial Stone ManufacturingCultured marble is a filled polyester casting, not quarried stone. What the resin does in that system, why the filler does most of the work, and what to settle before a production run.DMC and SMC Compression MouldingCompression moulding turns a pre-made compound into a finished part under heat and pressure. Where the resin sits in that chain, and why it is bought differently from a lay-up resin.Polyester Button ManufacturingButtons are cut from cast polyester sheet or rod, not moulded one at a time. What that means for the resin, and why clarity and a controlled cure matter more than strength.Engineered Quartz and Cast Stone Surface ManufacturingA quartz surface is mostly mineral held together by a small fraction of resin. What the binder has to do at that loading, and why it is a different job from cultured marble.
Tanks, Roofing & Structural Sheet
14 guides
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.
Cooling TowersWhich resin grade suits which cooling tower component — casings, fan stacks, louvres and basins — and how water treatment, temperature and lay-up method decide the choice.
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 Panel ManufacturingGeneral FRP panels — from partitions to enclosures — need a resin that processes predictably at volume, batch after batch.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.

Why an isophthalic laminate is the usual answer there, and what decides whether it is enough.Coloured FRP Sheet and Cladding ManufacturingOpaque coloured sheet for outdoor use, made on an ordinary catalysed line. What UV stabilised actually buys, and why it has nothing to do with curing under a lamp.UV-Stabilized Resin for Sunlight-Exposed Roof-Light SheetsClear roof-light sheets and translucent panels that sit in direct sunlight, made with the UV-stabilized clear grade SPR 201 RL (UV), and when to choose it over the standard roof-light resin.FRP GratingsChoosing resin for moulded FRP gratings, walkway panels and trench covers — where a general-purpose grade is enough, and where the chemical area calls for isophthalic or vinyl ester.Doors & Furniture Lamination
9 guides
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 Door LaminationDecorative doors need a resin that bonds laminate and veneer sheets firmly to the door face, curing quickly enough for efficient press cycles.
Resin for Door Skin LaminationBonding a moulded FRP door skin to its core is a distinct step from moulding the skin itself, and depends on fast-curing resin and glass fibre reinforcement.Resin for Wooden Door LaminationSolid-wood and wood-core doors are commonly faced with a decorative veneer, bonded on with a fast-curing resin to protect and finish the timber surface.
Resin for Decorative Panel LaminationWall panels, partitions and architectural cladding are often faced with a decorative laminate sheet, bonded on with a fast-curing resin for a durable interior finish.
Resin for Decorative Plywood LaminationLR Resin bonds a decorative laminate or veneer face onto already-manufactured plywood — it does not make the plywood board itself.
Resin for Furniture LaminationLR Resin is one of several methods furniture manufacturers use to bond decorative laminate onto panels — alongside PU and contact adhesive systems.
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.Marine, Automotive & Gelcoat Finishing
7 guides
Resin for Boat & Marine ComponentsMarine and boat components need proven wet-out over glass fibre reinforcement and reliable strength once the laminate cures.
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.Gelcoat for Swimming Pools and Water SlidesA pool surface is wet, sunlit, chemically treated and touched by people all day. What that asks of a gelcoat, and where the honest limits of the answer sit.Fabrication Processes
10 guides
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 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.
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.

Epoxy Clear Casting Resin for River Tables & Wood FurnitureLive-edge river tables need a resin that stays optically clear against wood grain, resists shrinking away from the timber edge, and can be poured in successive ~30 mm stages to reach full tabletop thickness — exactly what Epoxy Clear Casting Resin's low-shrinkage, 2:1 epoxy system is formulated for.
Epoxy Clear Casting Resin for Jewellery & Decorative CastingSmall silicone moulds for jewellery and decorative pieces need a resin that captures fine detail, releases trapped air in a shallow pour, and cures crystal clear well within Epoxy Clear Casting Resin's medium-depth capability.
Epoxy Casting Process: Mixing to FinishingEpoxy casting is a different discipline from polyester lamination — weighed rather than dosed by percentage, degassed rather than simply rolled, and cured over days rather than minutes. This guide covers mixing, pouring and finishing Epoxy Clear Casting Resin correctly.Polyester Clear Casting Resin for Statues, Idols and Decorative ArticlesCasting statues, idols and decorative articles, and top-coating furniture, with the clear orthophthalic polyester casting grade SPR 201 CC — and how it differs from the epoxy Clear Casting Resin.General FRP Applications
