Methods for making a B-stage thiol-cured urethane acrylate elastomeric film are provided. At least a urethane acrylate oligomer, a multifunctional thiol, and a base catalyst are combined to form a thiol terminated B-stage elastomer. The thiol terminated B-stage elastomer is exposed to an ultraviolet photoinitiator in the presence of an allyl ether terminated urethane to form the B-stage thiol-cured urethane acrylate elastomeric film. In some embodiments the B-stage thiol-cured urethane acrylate elastomeric film is used for a soft actuator application such as a fluidic elastomer actuator application or an electrostatic zipping actuator application.
