Betolin HT Liquid Hardener for Silicate Binders Chemical description
Betolin HT is an organic hardener susceptible to acids and alkalis. It can be applied in silicate emulsion coatings.
Mode of action
Betolin HT is saponified by alkali silicates. Due to the thus induced alkali consumption the ratio SiO2 : M2O of the binder is raised resulting in a strong viscosity increase up to solidification and hardening of the binder. The curing time depends on the added amount of Betolin HT and the system temperature.

Properties
-
Accelerates the setting and curing process of silicate emulsion coatings, Betolin HT is decomposed (saponified) by acids and alkalis, Non toxic, Biodegradable and ecocompatible, Does not contribute to VOC values.
Application
Betolin HT is mixed with silicate paints and plasters as a hardener immediately before application. The usually added quantities are between ca. 5 and 10 weight % relative to the silicate binder content. (Temperature dependent / preliminary tests necessary.)
Storage
Storage stability in closed original containers at least 12 months.
Labelling / Safety
Not classified as dangerous according to EC Guidelines and German Ordinance on Hazardous Materials (GefStoffV).
Packaging
