Abstract
PURPOSE: To enable the production of a molded product having an even thickness and excellent crack-proof property, by a method wherein, after melamine resin is premolded, a gaseous substance is blown against a position where a coating material is placed, and the coating material is then charged.
CONSTITUTION: In the case of a melamine resin molding, air or other gaseous substance is blown against a central section 2' after, for example, a bowl 1' is premolded. A coating material is then charged to perform a second sted molding, and a molded product, which is coated in an uniform thickness by the use of the coating material, can be obtained.
Process for the production of a latex composition which is processable into a non-gelling vulcanizable solid foam and a process for coating a substrate with said foam
