- Application Details
- 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 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.

Safety & Health
- Safety Note
Reaction with atmospheric moisture produces acetic acid, which is responsible for any strong odor or corrosive effect that may develop. Avoid contact with the skin. Cured silicone formulations containing WACKER® ANCHORAGE ADDITIVE HF 87 exhibit no skin irritation potential.
