After the artificial prosthesis is formed, it is not easy to color the surface of the object. Only use the special oily color paste for platinum silicone rubber and the well-balanced platinum silicone rubber, add the color paste, stir, and paint by hand. When the pigment is painted on the surface of the artificial prosthesis, it is easy to produce thickness, and it is not easy to spread evenly. The amount is small, the drying and solidification is fast, and it is very easy to form pimple particles.

In order to solve the above problems, it is necessary to mix the diluent with oily toner, and use a 0.2~0.3 caliber spray gun to spray the color, which can solve the phenomenon of damage to pores and texture distortion. Maintaining and replenishing color is also easy to bet on the spray gun, and the thinner is a silicone solvent, which has certain doubts about the use of health.
