Iso - NPG Gelcoat

ISO NPG Gelcoat is a thixotropic, quick-curing isophthalic-neopently glycol unsaturated polyester resin for general coating purposes. It is neither waxed nor pre-accelerated and is suitable for both hand lay-up and gun spray-up applications. However, gun spray-up application is preferable because it can apply the resin evenly and spread a thin coat without causing any pinholes.
