Before leaving the factory for leather color paste production, most color paste manufacturers conduct strict testing, with many testing items. Regular color paste manufacturers have more than ten goals for testing, such as light resistance, weather resistance, color paste fineness, and storage stability, which are all methods to determine the quality of color paste.

The shelf life of leather color paste is closely related to the skills of the color paste manufacturer. Even after the warranty period, the color paste produced with high skills can still maintain excellent fluidity without sedimentation or layering. Some low-quality products, sometimes when customers receive the color paste, have become very thick, lose liquidity, and there is still a long time before the product expires. This type of color paste has a short shelf life.

The shelf life varies depending on the color paste product. Fluorescent series color pastes, due to the coating of fluorescent resin, have a shorter shelf life than general water-based color pastes. There are some special color pastes, which have difficulty and stability due to the characteristics of pigments. For example, there is an environmentally friendly tender yellow paste with a shelf life of only 6 months.

Every customer should understand the objectives and shelf life of the color paste before purchasing it. Before use, open the leather color paste packaging bucket and carefully check if there are any lumps in the color paste or if there is any deposition at the bottom. When you see obvious situations such as layering and lack of fluidity in the color paste, you should promptly contact the color paste manufacturer or distributor, and do not use it randomly to avoid losses.
