ZAP Z-POXY Finishing Resin PT-41 — also known as laminating epoxy resin, fibreglass epoxy resin, hobby finishing resin, or two-part laminating resin — is the compact 4oz (118ml) version of the Z-POXY Finishing Resin formula, sharing the identical formulation as the larger Z-POXY Finishing Resin PT-40 12oz but in a smaller kit sized for smaller fibreglassing, foam sheeting, and wood sealing applications. Like the PT-40, it is fundamentally different in purpose and formulation from the structural bonding Z-POXY epoxies in the range — where the Z-POXY 5 Minute, 15 Minute, and 30 Minute formulas are engineered for structural adhesive bonding, Z-POXY Finishing Resin is specifically formulated as a laminating and surface finishing resin designed to wet out glass cloth, penetrate porous materials, create a smooth sandable surface, and produce a lightweight protective coating or laminated skin over RC model aircraft structures, boat hulls, foam wing panels, and wood surfaces.
The ZAP Z-POXY Finishing Resin PT-41 is a 4oz (118ml) two-part epoxy laminating resin with a 20–30 minute working time, hard in 3–4 hours, and a full cure of 6–8 hours. It is trusted by RC model aircraft builders, boat builders, foam aircraft builders, and woodworkers across UAE, Saudi Arabia, Qatar, Oman, Kuwait, and Bahrain as the go-to fibreglass laminating and surface finishing epoxy for smaller-scale hobby workshop tasks. Compatible with many polyester resins, very low odour, easy to sand between coats, and non-brittle, Z-POXY Finishing Resin PT-41 produces a hard, smooth, paintable surface on fibreglassed structures and a deeply penetrating, weather-resistant seal on bare wood. Maisam Trading LLC is the authorised ZAP Adhesives supplier in Dubai, with stock available for prompt delivery across the entire GCC region.
ZAP Z-POXY Finishing Resin PT-41 is the compact-format version of the purpose-built laminating and surface finishing epoxy in the Z-POXY range — not a structural adhesive, but a specialist lightweight resin engineered for fibreglassing, surface lamination, foam sheeting, and wood sealing applications where low viscosity, very low odour, easy workability, sandability, and long working time are the defining requirements. The 4oz kit is the practical choice for RC model aircraft builders working with glass cloth on wing centre sections and smaller structural areas, foam wing panel sheeting, boat hull spot repairs and sealing, and woodworkers applying a sealing or finishing coat to wood projects — wherever the task at hand does not require the larger volume of the 12oz PT-40 kit.
The lightweight, low-viscosity formula wets out glass cloth efficiently and penetrates porous wood surfaces naturally — no thinning is required for most applications, though thinning in small ratios is possible when even greater penetration is needed. Multiple coats may be required on highly porous wood surfaces: allow each coat to cure fully, then sand lightly between applications. The formula sands easily once cured — hard in 3–4 hours and fully cured in 6–8 hours — accepting paint primers cleanly and producing a smooth, flat surface ready for finish coats. Compatibility with many polyester resins makes Z-POXY Finishing Resin a versatile choice across mixed-material hobby builds and fibreglass repair work.
The 20–30 minute working time provides ample time for applying and smoothing glass cloth over curved surfaces, working resin into surface details, and ensuring uniform wet-out across the lamination area before the resin begins to gel. The cured resin is hard, non-brittle, bonds to itself for multi-coat applications, and does not yellow with age — making it equally suitable for outdoor weatherproofing, fibreglass repair, and long-term surface protection. Cleanup of uncured resin is straightforward using isopropyl alcohol or methanol.
For structural bonding rather than laminating and finishing, ZAP recommends the Z-POXY 30 Minute PT-39, Z-POXY 15 Minute PT-35, or Z-POXY 5 Minute PT-37 formulas. For larger fibreglassing and laminating jobs requiring greater volume, the Z-POXY Finishing Resin PT-40 12oz is available. As a trusted two-part epoxy resin GCC supplier, Maisam Trading LLC stocks the complete ZAP epoxy range for prompt delivery across Dubai, Saudi Arabia, Qatar, Oman, Kuwait, and Bahrain.

Q1: What is ZAP Z-POXY Finishing Resin 4oz (PT-41) used for? ZAP Z-POXY Finishing Resin PT-41 is a premium lightweight 2-part epoxy laminating and finishing resin used for fibreglassing RC model aircraft wing sections, sealing model boat hulls inside and out, sheeting foam wing panels, sealing engine and fuel tank areas, and sealing and finishing wood projects for painting, weatherproofing, and surface protection. It is a laminating and finishing resin — not a structural bonding adhesive. For structural bonding, use the Z-POXY 30 Minute, 15 Minute, or 5 Minute formulas. The 4oz PT-41 kit is the compact-size version of the identical PT-40 12oz formula — ideal for smaller tasks.
Q2: What is the difference between PT-41 (4oz) and PT-40 (12oz)? PT-41 and PT-40 contain identical Z-POXY Finishing Resin formula — the only difference is volume. PT-41 is a 4oz (118ml) kit suited for smaller fibreglassing sections, foam sheeting on sport models, and smaller wood sealing jobs. PT-40 is the 12oz (354.9ml) kit for full-aircraft fibreglassing, large hull lamination, and projects requiring greater volume of finishing resin. Choose based on the scale of your project.
Q3: How long does ZAP Z-POXY Finishing Resin PT-41 take to cure? Z-POXY Finishing Resin PT-41 provides 20–30 minutes of working time after mixing, is hard in 3–4 hours, and reaches full cure in 6–8 hours. The longer cure time is a deliberate feature of the laminating formula — it allows complete, unhurried glass cloth application and wet-out before the resin begins to gel. Do not sand or prime the surface before full cure is reached.
Q4: How many coats are needed when sealing wood with PT-41? Z-POXY Finishing Resin will penetrate into porous wood surfaces. On highly porous wood, several applications may be required to fully fill and level the surface. Allow each coat to cure completely, sand lightly between coats, and continue until a smooth, fully sealed surface is achieved — then prime and paint as normal.
Q5: Is Z-POXY Finishing Resin PT-41 the same as the structural Z-POXY bonding epoxies? No — Z-POXY Finishing Resin is a different formulation with a different purpose. The 5 Minute (PT-36/PT-37), 15 Minute (PT-35), and 30 Minute (PT-39) Z-POXY formulas are structural bonding adhesives. Z-POXY Finishing Resin (PT-41) is a lightweight, low-viscosity laminating and surface finishing resin engineered for glass cloth wet-out, foam sheeting, and wood sealing — not for primary structural adhesive joints.
Q6: Can Z-POXY Finishing Resin PT-41 be used on foam? Yes — Z-POXY Finishing Resin is considered the best choice for sheeting foam wing panels with balsa or glass cloth in RC model aircraft construction. Its low viscosity wets out glass cloth efficiently and bonds the skin to the foam core without adding unnecessary weight to the structure.
Q7: Is Z-POXY Finishing Resin PT-41 compatible with polyester resins? Yes — Z-POXY Finishing Resin is compatible with many polyester resins, making it a versatile choice for mixed-material hobby builds and fibreglass repair projects where both epoxy and polyester resin materials are present in the same structure.
Q8: Does Z-POXY Finishing Resin PT-41 yellow over time? No — Z-POXY Finishing Resin does not yellow with age. It cures to a light yellow/clear finish that remains stable over time, and the cured surface does not become brittle — making it suitable for long-term outdoor weatherproofing and surface protection applications.
