SILESTER XAR

SILESTER XAR is a ready-to-use, prehydrolyzed ethyl silicate hybrid binder. The solvent in SILESTER XAR is a mixture of ethanol and 2-propanol. The main difference between ethyl silicate hybrid binders and conventional acid-catalyzed ethyl silicate hydrolyzates is that the binder (SiO2) generated during setting is formed from ethyl silicate and another source of amorphous silica. Due to their special formulation and the technology used in their manufacture, hybrid binders have very good storage stability and processing properties.
