RENIA – ProtoColle Flexibel – Elastic Superglue for Leather & Flexible Trims
Renia ProtoColle Flexibel is a specially modified, flexible cyanoacrylate adhesive developed in Germany by Renia GmbH. Unlike standard rigid superglues that crystallize and snap under movement, ProtoColle Flexibel forms a tough, elastic bond line that flexes and bends naturally with the material.
Formulated specifically for porous and absorbent substrates, it stays on the surface of leather, suede, and flexible elastomers rather than soaking through, providing high-strength bonding in seconds without an activator.
Key Highlights & Advantages:
- Permanently Elastic: Resists repeated flexing, vibration, and dynamic tension without cracking or becoming brittle.
- Formulated for Absorbent Materials: Prevents excessive soak-in on open-pore leathers, suede, and technical fabrics.
- Fast Reaction Time: Bonds flexible substrates in just a few seconds without requiring a separate chemical activator.
- Crystal-Clear & Non-Staining: Dries clear and transparent, preserving material appearance and suppleness.
- Vibration & Shock Resistant: Absorbs chassis movement, road vibration, and joint flexing.
Recommended Materials & Applications:
- Automotive & Marine Trimming: Bonding cut leather edges, steering wheel wraps, seat seam repairs, flexible vinyl mouldings, and pliable rubber trims.
- Leathercraft & Saddlery: Instant edge bonding, tacking multi-layer leather assemblies before stitching, and strap/belt repairs.
- Footwear & Orthopaedics: Flexible sole bonding, lining repairs, soft rubber edges, and elastic orthotic components.
Application & Technical Guide:
1. Preparation: Ensure leather and rubber surfaces are clean, dry, and free of grease.
2. Application: Apply a thin drop or line of ProtoColle Flexibel to ONE surface only.
3. Assembly & Pressure: Join pieces immediately and press firmly by hand for 10–15 seconds.
4. Curing: Immediate green strength allows instant handling; full cure is reached within 1–2 hours.
