Extend Pot Life  
Smooth-Cast 321 & 322 Offer Extended Pot Life
Smooth-Cast 320 has long been popular with model makers and casters who paint or pigment their pieces and do not require the bright white finish of the Smooth-Cast 300 Series liquid plastics. In response to customer requests, Smooth-Cast 321 and Smooth-Cast 322 were developed to offer longer working times for these materials.

Smooth-Cast 320 features a 3-minute pot life and a 7-10 minute demold time (depending on mass). Smooth-Cast 321 has a 7-9 minute pot life and 30 minute demold time, while Smooth-Cast 322 has a 10-20 minute pot life and a 2-4 hour demold time.
