Neogel 8366-W-0100 is a pre-accelerated gelcoat formulated for fabricators who need a high-gloss, easy-to-repair surface finish with excellent styrene resistance and no foaming during cure. Buyers sourcing Neogel 8366-W-0100 for spray-applied gelcoat work benefit from a ready-to-use system with good general performance across a range of mould types.
Key Benefits of Neogel 8366-W-0100
This gelcoat has good general performance and is easy to apply and to repair. Fabricators evaluating this product for spray application cite the following characteristics as the deciding factors.
- High gloss finish for visible gelcoat surfaces
- High elongation at break for improved crack resistance
- Excellent styrene resistance compared to general-purpose gelcoats
- Easy to apply and easy to repair after cure
- Cures without foaming or microporosity, unlike many traditional vinyl ester resins
Application and Spray Settings for Neogel 8366-W-0100
Neogel 8366-W-0100 is pre-accelerated and ready for use. It can be cured with standard MEKP, such as Butanox M50 or an equivalent grade, without the foaming or microporosity issue that is typical for many traditional vinyl ester resins. The gelcoat has excellent spray properties and can be applied with conventional spray equipment.
Recommended Spray Gun Settings
For conventional spray guns, use a nozzle diameter of 2.5-3.5 mm at a pressure of 4-5 bar. These settings help maintain consistent film thickness and gloss across the mould surface.
Recommended Airless Equipment Settings
For airless equipment, a nozzle of 19/40 or 17/40 is recommended for smaller moulds, at a pressure of 3.5-4 bar with air assist at a maximum of 6 bars. Because the nozzle is relatively small, an internal filter of 100 mesh at the spray gun is recommended to prevent clogging.
Qualifying Spray Settings Before Full Production
Fabricators switching to this gelcoat from another spray system should run a trial panel to confirm nozzle selection, pressure, and filter mesh match their shop conditions before committing to a full production run, since ambient temperature and equipment condition can shift the optimal settings slightly.
Storage Recommendations
Pre-accelerated gelcoats of this type should be stored away from direct sunlight and heat sources to preserve pot life and avoid premature gelling in the container. Buyers ordering larger volumes should coordinate delivery timing with their spray schedule so material is used within its recommended shelf life rather than sitting in inventory for an extended period.
