なる。As a composite resin for a button spacer, it is preferable to use a homogeneous epoxy resin when the resin is an epoxy resin, and the height of the spacer depends on the amount of filler mixed in the resin and the thixotropic Adjust according to performance and discharge amount. However, if the resin is cured without changing its direction after being discharged, it becomes difficult to control the height of the synthetic resin spacer by changing the discharge amount. In this case, the height will be approximately constant depending on the viscosity of the resin and the chicken tropic property.
