Environmental Performance Of Water-based PU Ink Has Attracted Much Attention

At present, a series of water-based PU ink products are almost close to traditional ink in operation. It is composed of water, water-based resin, pigments and additives that meet environmental protection requirements. In the process of production, pure water is used as the solvent, so there will be no combustion, explosion, irritating odor or toxic substances volatilization. Nowadays, it is a relatively environmentally friendly ink among printing ink products, so the environmental performance of water-based PU ink is favored by printing, nail, shoe and other industries.

However, water-based PU ink is based on water as solvent, food, medicine, children's toys, alcohol and tobacco packaging enterprises in the process of use is still very different from the traditional oily ink, in order to let customers can master this new environmental protection ink, Xiaobian suggests that the use of water-based PU ink should pay attention to the following points:
First, the use of water-based PU ink before the need to fully stir evenly, to ensure that the composition of water-based PU ink to maintain a uniform state;

Second, after starting the use of water-based PU ink, the remaining parts need to be covered and sealed immediately, to ensure that the water-based PU ink does not dry and solidified, but also to prevent the surrounding environment such as dust falling in the water-based PU ink, affecting the quality of its products;

Third, if there are impurities found in the remaining water-based PU ink, it must be filtered first, and then used together with the new ink;

Fourth, if the use of water-based PU ink found that its viscosity is a little big, can be appropriate to add water to adjust its viscosity;

Fifth, during the storage of water-based PU ink need to find a cool and dry location, that because of high temperature or the sun irradiation of water-based PU ink storage, it will easily lead to the deterioration of water-based PU ink products, general cool and dry storage, can make water-based PU ink will not deteriorate within a year.
