What should I know before buying PU color paste?

Before purchasing PU color paste, you should understand the relevant indicators and shelf life of PU color paste. Light resistance, weather resistance, color paste fineness, and storage stability are all methods to judge the quality of color paste.

The color paste produced by the adopted technology can still maintain very good fluidity even after the warranty period, without precipitation and stratification.

Some inferior products have become very thick and have no fluidity for a long time before the product expires, so the shelf life of such color paste is very short. In addition, different color paste products have different shelf life.

Open the PU color paste packaging barrel before use, and carefully check whether the color paste is agglomerated, or whether there is sediment at the bottom. When you see that the color paste is layered and has no fluidity, you should contact the PU color paste manufacturer or distributor in time, and do not use it at will to avoid losses.
