Polyurethane adhesives

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

 

Range PUR 701 (1 or 2 components) Special adhesive to bond non-halogenated, non-carded elastomer soles (check the elastomer quality), and Louis XV-type unitary soles. It is ready to use and can be used for both elastomer soles and uppers. Important: its lifetime is limited to 3-4 months.” Technical notice
Fiche de sécurité
Range PUR 702 (2 components) Two-component adhesive with more flexible film, low reactivation temperature (approx. 50°C). Working time of one minute after reactivation, recommended for attaching foxing, dished soles (possibility of correcting the adhesive film after positioning) as well as for pre-glued synthetic fabrics and to improve the bonding of the adhesive film. Very good hydrolysis behaviour.” Fiche technique
