Apart from the widely introduced silicone and polyurethane systems, also hybrid prepolymers based on silane terminated polyurethanes (STP-U) offer themselves for the preparation of sealants and adhesives. They combine the benefits of a polyurethane base structure with a silane based curing mechanism.

ADVANTAGES OF USINg CALCINED NEUBURG SILICEOUS EARTH

  • Very low moisture content and very low moisture absorption even under humid conditions
  • Significant lower viscosity at higher deformation, thereby easier application
  • Viscosity at low deformation / yield point variably adjustable 
  • High hardness
  • Increased tensile strength of up to 14 MPa
  • Marked increase of lap shear strength, more than 16 MPa are possible
  • Potential for reducing rheological additive fumed silica
