It is common. However, the ratio of the curing agent component to the main component is 2 to 50 parts by weight of the curing agent per 100 parts by weight of the main component.
It is 2 to 20 parts by weight with respect to 00 parts by weight.

成分を着色するのが一般的である。2. Description of the Related Art Conventionally, when applying a two-component polyurethane adhesive using a two-component fixed-quantity mixing / dispensing apparatus, work is performed on the premise that the mixing ratio once set is accurate and uniform. However, in the actual line, since the isocyanate compound, which is a curing agent component, reacts sharply with moisture, there are many troubles affecting the mixing ratio such as clogging of a transfer pipe. In addition, when coloring a two-pack polyurethane adhesive, it is common to color a main component having low reactivity.
