    Abstract: An intumescent article includes intumescent material including 50-92 wt-% graphite and 8-50 wt-% binder, and may have a free expansion ratio of 100× or greater and a free expansion aspect ratio of 1.0 or less. The intumescent article may be a sheet, and may be L-shaped, rectangle, triangle, or other shape. The intumescent article may have a 3D shape. The intumescent article may be an insert for an electrical box, having a surface area 75% or less of the surface area of the electrical box back wall. The intumescent sheet has a mass, and the ratio of the mass to the volume of the electrical box may be 3 g/100 cm3 or less. A method of making an intumescent article includes mixing from 50-92 wt-% graphite with 8-50 wt-% binder on a dry weight basis to form a mixture, pressing or molding the mixture into a shape and drying the shape.

    Abstract: A method for painting a complex or compound curved three-dimensional surface of a portion of an article. The method comprises providing a paint film (24); providing sheet metal (26) having opposite major surfaces; laminating the paint film onto a major surface of the sheet metal to form a painted sheet metal laminate (22) comprising a first portion and a second portion; permanently deforming the first portion of the painted sheet metal laminate into a formed portion of the article having a complex or compound curved three-dimensional shape; applying an initial force for securing the second portion of the painted sheet metal laminate during an initial stage of said permanently deforming step; and applying a later force for securing the second portion of the painted sheet metal laminate during a later stage of said permanently deforming step. The later applied force is greater than the initially applied force.

    Abstract translation: 用于对制品的一部分的复合或复合弯曲的三维表面进行喷涂的方法。 该方法包括提供漆膜（24）; 提供具有相反主表面的金属片（26）; 将所述漆膜层压到所述金属板的主表面上以形成包括第一部分和第二部分的涂漆的金属板状叠层体（22）; 将被涂覆的金属片层压体的第一部分永久变形成具有复合或复合弯曲三维形状的制品的形成部分; 在所述永久变形步骤的初始阶段期间施加用于固定所涂漆的金属片层压板的第二部分的初始力; 以及施加稍后的力以在所述永久变形步骤的后期阶段中固定所涂漆的金属薄板的第二部分。 稍后施加的力大于最初施加的力。
