Perkacit ZMBT's main function is as secondary accelerator in sulfur curde latex. In dry rubber applications,Perdacit ZMBT is a moderately fast curing primary accelerator.
- In iatex vulcanization Perkacit ZMBT is used in combination with Perkacit ZBEC, Perkacit ZDMC or Perkacit ZDEC.
- By using Perkacit ZMBT,markedly higher moduli in latex films are obtained than with dithiocarbamates alone
futhermore a better compression set resistance in latex foam can be achieved, without increasing the cure time.
- Perkacit ZMBT does not destabilize latex formulations.
- In latex thread applications the low free MBT grade of Perkacit ZMBT (pdr-s) bives reduced extraction of MBT during acid coagulation (acid bath pollution) and helps to stabilize the viscosity of latex compounds durting storage.
- In dry rubber applications the performance of Perkacit ZMBT is almost similar to Perkacit MBT,but with a slight scorch improvement.
- Perkacit ZMBT is regulated for use in articles in contact with food as specified under FDA 21 CFR 177.2600, 175.105, 178.3120 and under BgVV XXI, Categories 3-4.
