Remmers KSE 300 can be used to strengthen medium pored, absorbent and friable mineral building materials, preferably sandstone. It can also be used to strengthen historical renders and joints.

Properties

Remmers KSE 300 reacts with water stored in the pore system or humidity. During this reaction, amorphous and hydrous silicon dioxide (SiO2,aq, "silica gel") is deposited as a binder. The mineral silica gel binder thus replaces the original binder lost through weathering. The speed of the gel deposit reaction is very dependent on temperature and humidity. Under normal conditions (20 °C, 50 % relative humidity), the deposit of binder is concluded after approx. 3 weeks.

Reaction:

Si(C₂H₅O)₄ + 4H₂O  → Si(OH)₄ + 4C₂H₅OH ↑

Si(OH)₄ → SiO₂ + 2H₂O

In the following, the most important property parameters of KSE 300 are given:
