Colle de Cologne

Renia organic solvent-based neoprene contact cement without toluene or MEK

Instructions

Clean or grind all materials and coat them with Colle de Cologne until you can see a layer of cement.

PE, PP: Touch with an open gas flame.

TR (Thermoplastic Rubber): Apply Renia - Rehagol and coat with Colle de Cologne after 10-15 minutes.

Expanded PUR (Polyurethane): After grinding, press the material together with paper to remove the water, if necessary. Then coat it with Renia-Primer for PUR to reinforce very soft polyurethane. Apply Colle de Cologne without delay.

• pot life: 4-6 hours if mixed with hardener
• open assembly time: 5-30 minutes (TR 3-15 minutes, PVC 10-45 minutes)
• can be dried with infrared 80°C 3 minutes
• pressure: 1-5 bar, material dependent
  • 1 bar minimum time 60 seconds
  • 3 bar minimum time 15 seconds
  • the softer the material, the less pressure needed

Highlights

Due to the fast crystallisation and the high initial bonding strength of Colle de Cologne, it is possible to handle the bonded pieces after a few minutes. The heat resistance is high enough to trim or buffer the material. The bonding strength increases continuously during the first two days. Adding 5-10 % hardener greatly increases the resistance against heat, oil and other chemical influences.

• shelf life: 12 months at 20°C
• cleaner: their cleaner or acetone
