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. SILRES® BS 6921 is a transparent, low viscosity binder. 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. GENIOSIL® GF 80 (~ 4 %) is recommended. 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 Applications : • Concrete Flooring • Stone Carpets • Industrial Coatings
