Characteristic Performance

Neomould® 1982-W-1’s ability to cure quickly in thin layers, its low exothermic and zero shrinkage properties make it ideally suited for mold making.
The special formulation of Neomould® 1982-W-1 makes it easy to handle, quick to wet the fiberglass, and does not hang during application. Moreover, the color of the resin makes it easy to detect air bubbles. It does not stick to the hands after curing and does not affect the secondary laminate bonding.
The maximum accumulation of layers is 5mm per time, and the thickness required by ordinary molds can be reached in two times.
