Neogel 8373-I-0000: A Transparent ISO-NPG Gelcoat for FRP Manufacturers
Neogel 8373-I-0000 is a transparent ISO-NPG gelcoat sourced by FRP manufacturers and boat builders who need excellent appearance, good mechanical properties, and reliable water and weather resistance in a single spray-applied system. Buyers comparing gelcoat options for translucent or clear-coat finishes often evaluate this product on UV stability, marine classification approval, and consistency of appearance across production batches.
Benefits
Neogel 8373-I-0000 combines excellent appearance and transparency with good mechanical properties and good resistance to water and weather. It is UV stabilized and approved by RINA, making it a suitable choice for buyers who need marine-classification documentation to support their own end-customer requirements.
Application and Processing Guidance
Neogel 8373-I-0000 is pre-accelerated, thixotropic, and ready for use, supplied in a Spray type for application with conventional equipment. Recommended settings include a spray gun with a 2.0-3.5 mm nozzle at 4-5 bar pressure, or airless equipment using nozzle types 18/40-21/40. It can also be supplied in a Paraffinated Spray version (Neogel 8373-T-0000) on request.
To obtain optimum performance, buyers should apply this gelcoat at a temperature between 18°C and 25°C, cure with a recommended MEKP 50% catalyst solution such as Butanox M50 (Akzo Nobel) at 1.0-2.5% dosage, and target a film thickness of 500-600 g/m². For buyers building out a broader resin and gelcoat program, our technical team can help confirm catalyst dosage and film build for your specific mold and part geometry.
Why Transparency and UV Stability Matter
A transparent gelcoat like Neogel 8373-I-0000 is typically specified when the finished part needs to show underlying fiberglass reinforcement patterns for aesthetic or quality-inspection purposes, or when the application calls for a clear protective topcoat rather than a pigmented finish. UV stabilization is important for outdoor and marine parts, since unstabilized clear gelcoats can yellow or lose clarity after extended sun exposure.
Sourcing Considerations for FRP Buyers
Buyers should confirm shelf life, gel time, and catalyst compatibility against their own mold temperature and cycle time before scaling up production. For plastics and composites testing standards referenced across the FRP industry, see the ASTM D20 committee on plastics.
Comparing Transparent and Pigmented Gelcoat Options
Buyers who typically source pigmented gelcoats sometimes ask why a transparent grade would be specified at all. Beyond aesthetic and inspection use cases, a clear topcoat can also simplify color-matching logistics for buyers who apply their own pigment systems downstream, or who need a single base gelcoat that can be tinted to multiple final colors from one inventory item. This can reduce the number of pre-pigmented SKUs a buyer needs to stock while still meeting a range of finish requirements across different production runs.
