Applicable Base Polymer Properties

TMS 30000 Polymer – It is Polypropylene glycol polyol, PPG, chain extended with an isocyanate molecule, and then terminated with isocyanato propyl trimethoxy silane. No tin catalyst content.

  • There are 4 urethane groups in each chain, that allow for hydrogen bonding across Polymer chains and plasticizers that contain a C=O group.
  • There are 3 methoxy groups that crosslink with a little DBTDL catalyst.

It has excellent UV resistance.
