Paste, for their performance, we should understand and master their, what does? In addition, water-based paste in terms of its storage stability mean? These many, all about paste, are also following small series will be focuses of. So, as soon as possible in order that we can understand, then, without further ado, immediately expand it concretely, we want to make gain.

Paste performance and physicochemical parameters are:
Acid and alkali resistance: DIN16524 standards should be based, first paste drying, and then placed in a concentration of 1% sulfuric acid and 2.5% sodium hydroxide solution, soak 24 hours after removal and washing, then measuring their acid and alkali resistance. Are generally divided into five levels to be assessed, the higher the level, the acid and alkali resistance, the better.
Density: unit is g / cc, reference should be GB / T 1756 standard were measured.
Viscosity: It is an important indicator paste storage stability.
PH: 7-10 should be kept within this range, because its performance is optimal.
Size and gloss: mainly smaller the particle size, the better the gloss.
Aqueous paste storage stability at room temperature refers to about 25 ℃, storage time of year to see if there is stratification, agglomeration, back rough, precipitation and other issues, there is its coloring power, color and other physical and chemical exhibition performance is reduced. If not, then its good stability.
