When dried it tightens  the canvas , recommended to add an oil based primer for use under oil
-
Rabbit skin glue has hygroscopic therefore:
-
It absorbs atmospheric moisture on damp days and swells and also gives off moisture on dry days and shrinks therefore causes oil paintings to crack over time
-
Substitutes are Golden Acrylic GAC 100 Â or GAC 700 and Gamblin PV size ( both have some properties of hygroscopic but not the same as Rabbit skin glue ( you should add a few coats of acrylic gesso over these substitutes ) but the gesso is more flexible than oil paint which leads to tacking so people prefer the hard rigid materials of Rabbit Skin Glue

It’s a sizing that acts as  an adhesive when mixed with water and heated to just short of boiling point
-
Recommended dissolving at 60-63c ( 140 -145F)
-
If you overheat , it will reduce adhesive qualities
