What’s a suitable temperature for acrylic to cure and why?
Acrylics will cure just fine at normal room temperature. Cool temperatures will slow down the curing reaction, so in cool weather or in a cold room, it’s often helpful to warm the monomer a bit to speed up the curing and prevent crystallization.
Monomer can be warmed by putting the bottle in a bowl of warm water or by using a commercial dappen dish warming unit. Don’t warm monomer in a microwave or conventional oven, as this can cause explosion or fire. – Paul Bryson is director of research and development at OPI.
