Abstract
The present invention relates to a method of manufacturing an integrated piece comprising a convex cured product and a substrate, the method comprising a step of: depositing dropwise or dispensing a curable silicone composition onto the pre-heated substrate, the composition reaching a torque value of 1 dN·m within 60 seconds from immediately after beginning measurement as measured using a curelastometer according to JIS K 6300-2, at the temperature to which the substrate is heated, and having a viscosity at said temperature of at least 0.05 Pa·s. The method allows for the efficient manufacture of a hemispherical, hemicylindrical, dome-shaped, or similar convex cured product upon a substrate using a curable silicone composition.
