Overview
Neogel 8373-W-9504 is an iso/Neopentylglycol UV gelcoat that combines easy application with good resistance to long immersion in water (good blister resistance), excellent weatherability with less yellowing, air release, and good mechanical properties. As one of the recommended international brand products in our resin range, this gelcoat is supplied with supply chain resource support for composite manufacturers who need a certified, water-resistant finishing system.
Key Benefits of Neogel 8373-W-9504
- Easy application
- Good resistance to long immersion in water (good blister resistance)
- Excellent weatherability with less yellowing
- Air release
- Good mechanical properties
- Conforms to USA ANSI-Z-124-1
- Approved by DNV Italia and Italian RINA
Certifications and Why They Matter
This gelcoat conforms to the USA ANSI-Z-124-1 standard and is approved by DNV Italia and Italian RINA, two recognized marine vessel classification bodies. For fabricators building products intended for prolonged water contact, working with a gelcoat that already carries this kind of documented approval can simplify compliance and sourcing reviews, since the underlying resistance to water immersion and blister formation has already been evaluated against a recognized standard.
Product Types and Application Methods
This gelcoat is pre-accelerated, thixotropic, and ready for use, available in a wide range of colors in the following types:
- Spray type (Neogel 8373-W-9504 UV)
- Brush type (the UVH variant)
It can also be supplied in standard or additional versions on request, including paraffinated spray and paraffinated brush versions.
Recommended Application Parameters
The spray type can be applied with conventional equipment using these recommended settings: a spray gun with a nozzle of 2.0-3.5 mm at 4-5 bar pressure, or airless equipment with nozzle types 18/40-21/40.
To obtain optimum performance, it is advisable to operate as follows:
- Application temperature between 18°C and 25°C
- Cure with recommended MEKP* 50% solution, adjusting the amount between 1.0-2.5%
- Film thickness of 600-800 g/m²
*Butanox M50 (Akzo Nobel). Always confirm current application parameters against the latest technical data sheet before production use, since equipment, ambient conditions, and part geometry can affect optimal settings. Consistent film thickness across the part is important for any gelcoat where water-immersion performance is a key selection factor: under-application can leave blister resistance below the level tested and certified, while over-application can affect cure and finish quality.
