  • Solvent-free
  • Tin-free catalysis

Multipurpose glue and for textile coatings, e.g. antislip coatings

ELASTOSIL® E91 TRANSPARENT shows good primerless adhesion to many substrates. We recommend running preliminary tests to optimize conditions for the particular application. The one component silicone rubber can be easily extruded and cures at room temperature or steam curing under the influence of atmospheric moisture. 

Skin forming time at 23°C / 50% rH: about 15 min. 

Curing time at 23°C / 50% rH: 12 h/mm
