The viscosity and reactivity of adhesives are closely related to temperature. The viscosity of glue is measured by Brinell viscometer, and the unit is "cps centipoise". The viscosity reading of glue is generally between 300 and 30000 cps. In water-soluble adhesives, the solid content does not determine the viscosity of the glue, but the plasticizer, tackifier, etc. in the formula of the glue, which affects the viscosity value of the glue.

Common adhesives include instant adhesive (common - 1203 instant adhesive - ethyl cyanoacrylate strong instant adhesive is one kind), epoxy resin adhesive, anaerobic adhesive, UV adhesive (UV curing), hot melt adhesive, pressure sensitive adhesive, latex, etc.
