Primers, hardeners, additives

The assembly of TR, rubber, PU, PVC or leather soles on leathers with a high oil content or on synthetic fabrics requires the use of high-performance adhesives.

Our Keck PUR adhesives meet these criteria. We have mastered polymerisation techniques for more than 25 years. We select raw materials that deliver:

  • an immediate high tack after pressing with a hard film
  • versatility. The same adhesive can be used for a wide variety of soles
  • high temperature resistance to 80-85°C in one-component form and 110-115°C with hardener
  • good  humidity and hydrolysis  behaviour
