WACKER® ANCHORAGE ADDITIVE HF 87

WACKER® ANCHORAGE ADDITIVE 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 .


Properties

  • improved anchorage to unprimed PET-films
  • very effective with emulsion-based, solvent-based and solvent-free DEHESIVE® or ELASTOSIL® - systems
  • very effective as textile priming in aqueous solution
  • improved adhesion to almost all kinds of textiles

Specific features of WACKER® ANCHORAGE ADDITIVE HF 87

  • Additive
  • Solvent-free

WACKER® ANCHORAGE ADDITIVE 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® ANCHORAGE ADDITIVE HF 87. The standard concentration for this application is 4 wt %.

 

Processing


In mixtures with addition-cross-linking silicones the addition of WACKER® ANCHORAGE ADDITIVE 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® ANCHORAGE ADDITIVE HF 87. Furthermore, a viscosity increase can be observed upon the addition of WACKER® ANCHORAGE ADDITIVE HF 87 into liquid silicone systems. All standard mixing devices are suitable to mix WACKER® ANCHORAGE ADDITIVE HF 87.

Storage

The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
