SILRES BS 6921

SILRES® BS 6921 is a transparent, low viscosity binder used as a thin layer coating for mineral substrates and usually applied in combination with SILRES® BS 6920 in case of a softer formulation is required. Primarily, cure via amines is recommended, with particular focus on amino-silanes. Pot life as well as speed of through-cure can be adjusted by the aminosilane loading like GENIOSIL® GF 91 (~ 5 %). For application below temperatures of 15°C addition of catalyst (ca. 0.2%, e.g. TMG (1, 1, 3, 3-tetramethylguanidine)) is required. SILRES® BS 6921 is characterised by: • low viscosity • solvent and plasticizer free • easy handling and dosing • resistant to moisture • cure without tin catalyst • non-labeling.
