Renia Colle de Cologne - 'Glue from Cologne' All-Purpose Adhesive
Renia Colle de Cologne is a solvent-based contact adhesive made for leathercraft, footwear construction, and general workshop use. The brushable formula goes on clean, dries clear, and bonds a wide range of materials such as leather, rubber, EVA, cork, felt, and more, with a strong, flexible hold. It has a 30-minute open time, and if that window passes, the bond can be reactivated with heat. All Renia adhesives are 100% free of Toluene and MEK.

Contact Adhesives vs Pressure Sensitive Adhesives (PSAs)
- Contact adhesives bond instantly when both sides are joined and are difficult to reposition afterward.
- Pressure sensitive adhesives will not bond until pressure is applied and can be repositioned until then.
