WACKER® HAFTVERMITTLER HF 87

Haftadditive

WACKER® HAFTVERMITTLER HF 87 is a solvent-free, reactive silane mixture. Applied with addition-crosslinking DEHESIVE® - or ELASTOSIL®-systems it increases the adhesion to the substrate. The ruboff resistance of the cured silicone coating is improved significiantly .

WACKER® HAFTVERMITTLER HF 87 significiantly improves the anchorage of solvent-based, emulsion-based and solvent-free addition-curing silicones on unprimed PET-films and all kinds of textiles. It mixes perfectly with the the Dehesive® or Elastosil® formulations. The standard concentration in these systems is 0.5 – 2 wt %.

Combined with HTV silicones, a better anchorage can be obtained by priming the textile with an aqueous solution of WACKER® HAFTVERMITTLER HF 87. The standard concentration for this application is 4 wt %.

 

Processing


In mixtures with addition-cross-linking silicones the addition of WACKER® HAFTVERMITTLER HF 87 might influence the reactivity of the system. The extent of this effect has to be determined individually and depends on the amount of added WACKER® HAFTVERMITTLER HF 87. Furthermore, a viscosity increase can be observed upon the addition of WACKER® HAFTVERMITTLER HF 87 into liquid silicone systems. All standard mixing devices are suitable to mix WACKER® HAFTVERMITTLER HF 87.

Lagerung

Das Mindesthaltbarkeitsdatum der jeweiligen Charge ist auf dem Produktetikett angegeben. Eine Lagerung über den auf dem Produktetikett angegebenen Zeitraum hinaus bedeutet nicht notwendigerweise, dass die Ware unbrauchbar ist. Eine Überprüfung der für den jeweiligen Einsatzzweck erforderlichen Eigenschaftswerte ist jedoch in diesem Falle aus Gründen der Qualitätssicherung unerlässlich.
