* Available in 10 minute working times for faster demolds

Pot life, gel time, cure time, and demold time vary depending on quantity mixed, thickness of casting and mold temperature. The use of heated molds is recommended i.e. 100F (38C). Warming the mold will accelerate demold and decrease cure times. Low temperatures will slow the curing and extend demold time. Hardness development progresses more slowly in the longer working time / longer pot life materials. Post-curing for 6-8 hrs @ 160-175F will accelerate development of properties. Impact strength and heat distortion properties improve when the casting is post cured. Aliphatic urethanes are UV resistant / non-yellowing. Read label, Technical Data Sheet and Safety Data Sheet before use.
