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 .
- 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

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 %.
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.
