The viscosity of the glue is measured with a Brookfield viscometer in units of "cps centipoise". The viscosity of the glue is usually between 300 and 30000 cps. In water-soluble binders, the solids content does not determine the viscosity of the gel, but rather the plasticizer, tackifier, etc. in the formulation of the glue, which affects the viscosity of the glue. Under normal circumstances the ambient temperature is higher "viscosity ↓", "temperature ↓ viscosity ↑". The viscosity of water at 27 ° C is "1".
