Application
Neogel® 8393-W-XXXX is pre-accelerated, ready for use. It canbe cured with standard MEKP (Butanox M50 or equivalent), without any foaming (microporosity), which is typical for many traditional vinyl ester resins. The gelcoat has excellent spray properties and can be applied with conventional spray equipment with the following recommended settings:
• Spray gun: nozzle ∅ 2.5-3.5 mm, pressure 4-5 bar.
• Airless equipment: nozzle 19/40 or 17/40 for smaller moulds, pressure 3.5–4 bar, air assist maximum (6 bars). Due to the relatively small nozzle it is recommended to use an internal filter of 100 mesh at the spray gun.
