Heat cured acrylic resin
Web2 de nov. de 2024 · The heat-curing resin has a lower value of the elasticity modulus than the urethane-based resins. The values decrease distinctly in humid environment, especially in the case of Eclipse Base resin. The mechanical strength also shows decreased values for the humid samples, for all three resins tested in the present work. Web1 de ene. de 2015 · The chemistry of these resins is identical to that of the heat-cured resins, except that the cure is initiated by a tertiary amine (e.g. dimethyl-P-toluidine or sulphinic acid) rather than heat. This method of curing is not as efficient as the heat curing process, and tends to result in a lower-molecular-weight material.
