Koester - Injektionsgel S4 four-component acrylic gel

Four-component acrylic gel with adjustable reaction time. It is used for sealing leaks in and for curtain injection with an adjustable reaction time from 15 seconds to 3 minutes. It is used to stop leakage in cracks, expansion joints and work breaks.

Properties

• designed to seal a leak in
• for sealing expansion joints, construction joints and for curtain injection
• adjustable reaction time by changing the amount of component B
• the product can be set for a response time of 10 seconds to 3 minutes
• by adding a dispersion of plastics to component B (Koester B +), an acrylic gel is obtained with increased adhesion to mineral substrates
• the addition of a dispersion based on plastics shortens the reaction time of the gel by half
• it is possible to dye the gel on site by adding pigment
• The injection gel is resistant to all chemicals normally present in groundwater (e.g. dilute salts)

Application

• thanks to the use of the addition of plastic dispersion, a significant improvement of the edge gel in the expansion joint can be achieved and the flexibility of the material increases
• the reaction time is reduced by about half in relation to standard mixtures, it can be adjusted by the addition of salt
• for injection of dilatation, it is recommended to use mixtures with longer reaction times
• mixtures with shorter reaction times (e.g. in gravel ground) may be used to limit the area of curtain injection in edge areas
• it is also possible to achieve lower penetration of medium sand by setting a shorter reaction time
• in other cases, it is recommended to use acrylic gel, which is characterized by a very low viscosity, high penetration and reaction time of about 4 minutes
