Liquid animal glues are modified dry glue solutions containing a gel depressant, usually urea, thiourea, ammonium thiocyanate, or dicyandiamide, so that they remain fluid at and somewhat below room temperature. Liquid animal glues can be modified with clays or calcium carbonate as fillers, and wetting and dispersing agents, plasticizers, and other modifiers as required. Solids are usually in the range 35 to 65%, with a viscosity range of 3000 to 5000 cP at room temperature.
