Trimethylsiloxysilicate. BELSIL® TMS 803 by Wacker is a highly cross-linked silicone resin and film-former. It is the co-hydrolysis product of tetraalkoxysilane (Q unit) and trimethylethoxysilane (M unit). It exhibits excellent rheological properties and flowability due to low content of fine dust particles and its uniform particles.

  • It prevents agglomeration, and maintains free-flowing characteristics in loose powder products.
  • It is an excellent water-resistant additive and helps to hold pigments in place.
