Renia Top-Fit High-Power Adhesive Contact Cement
Renia Top-Fit is a solvent-based contact adhesive made for leathercraft, footwear construction, and professional repair work. This high-power formula is designed to create strong, flexible bonds across a wide range of materials such as leather, rubber, EVA, cork, felt, and more. With approximately 25 percent higher solid content than many standard contact cements, Top-Fit offers excellent durability, quick tack, and reliable performance for both structural builds and detailed repairs. The high tack allows it to bond effectively to oily or even damp materials, making it great for molding, saddle work, and field repairs. It dries clear for a clean finished appearance and can be used for cold bonding or 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.
