Renia Ortec Multi-Purpose Contact Cement
Renia Ortec is a solvent-based contact adhesive made for footwear, orthotics, leathercraft, and general workshop use. This professional-grade universal formula is designed to create strong, flexible bonds across a wide range of materials such as leather, rubber, EVA, cork, felt, foams, and more. As a polychloroprene-based adhesive, Ortec offers strong initial tack, dependable durability, and a practical working window for accurate assembly. It is also toluene-free, dries clear without yellowing, and can be used for both cold bonding and heat reactivation workflows. 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.
