In the sculpture industry, as well as for many spatial three-dimensional modeling art industry, FRP is widely used as mould and finished products manufacturing materials of sculptures because of their advantages of light weight, high strength and durability. In the general process of the FRP sculptures, the FRP mold is always made with resin, and its price and process are also favored by consumers.

In daily life, we see the finished FRP sculpture products with various colors, while the FRP itself is milky white. How to deal with different colors of FRP sculpture painting to satisfy the requirements of different sculpture products is the concern of many FRP sculpture factories. Before color treatment, the glass steel mold may have remained clay and sands left on it, so mold need go through thorough cleaning and polishing treatment.

The propylene pigment are mainly uesd for painting for appearance treatment generally. Taking the processing process of bronze color of FRP sculpture as an example: the alloy with 64% copper content is bronze, and the acrylic pigment coloring can achieve this bronze effect. First of all, using the dark pigment as the foundation color, fully mix water with the pigment completely to cover the surface of the sculpture. The main point is to paint evenly, not accumulated spots or show the foundation color situations. After air drying, fully paint the second time to highlight the visual effect of bronze rust. The light pigment can sue white and green pigment, fully mixed and smeared on surface of the sculpture. When all the pigments are completely dry, the bronze matte effect appears.

In addition to the techniques of process, the color processing in the later stage is also subject to the demands of FRP sculpture. Under different light or natural environment, sculptures appear different effects due to the lighting factors. To perfect the final effect, manufactures need to figure out the integration of various colors and textures, FRP sculpture process practitioners need to constantly explore in the actual shaping process.
