Isolan PTC-E is formulated as an NMP/NEP-free polyester-PUD binder, designed for impregnation and pile binding of fabrics and non-wovens. Isolan PTC-E can also be employed as a (pre)-skin for both transfer-coating and direct-coating processes.

  • Strong adhesion to natural and synthetic fabrics, along with PUR, PVC, and pretreated TPO foils.
  • An excellent foundation as a binder for crafting finishes or impregnation agents for synthetic fabrics and foils.
  • Provides a dry touch and acts as an effective barrier against plasticizer migration.
  • Its application can be achieved via methods such as rotogravure, wire bar, dipping, rotary-screen, knife, or reverse roller-coater. Depending on the chosen application technique, adjustments to flow, wetting, defoaming, and rheology may be necessary.


    The optimum storage and handling temperature range is 5 °C to 30 °C. The product must be protected from heat and frost in order to maintain viability. Containers must not be re-stocked after they have been opened. Properly stored, Isolan PTC-E is stable for at least 12 months after the shipment has left our warehouse.


    Isolan PTC-E is available in IBCs (1000kg each) and drums (210kg each). MoQ are 2 pallets with 8 drums each or 1 IBC.
