Hodogaya Chemical uses chemistry to add color to many of the objects that surround us. Our dyestuffs are used not only on textiles and paper, but in a wide variety of materials. Broadly speaking, there are four categories of dyes: Spilon dyes,  Basic dyes, and Direct dyes.

The Basic dyes we supply are excellent for paper coloring, while our unique organic-soluble Spilon dyes are used in stationery applications and aluminum coloring.

Spilon Dyes

Application 1~Aluminum Coloring

Consider, for example, the body of a digital camera, cellular phone, or digital audio player. Usually, these are made of lightweight, easy-to-process aluminum, and it has now become the norm for them to come in red, blue, and a variety of other vibrant colors. These colors are created using aluminum dyes.

Dyes for Aluminum

Aluminum dyes color metal, producing the characteristic rich colors shown in the photograph. A number of chemicals are combined with the dye to color the aluminum.

The Aluminum Coloring Process

The technical expertise and high levels of quality we have achieved as a result of our long experience with dyes allow us to handle even seemingly difficult materials such as aluminum.
