Caoutchouc silicone neutre (RTV-1), prêt à l'emploi, durcissant à température ambiante par l'action de l'humidité de l'air.
Il possède une très bonne résistance au vieillissement, intempéries, hautes et basses températures (-50°C à 150°C).
Caractéristiques :
Adhère sans primaire sur presque toutes les matières du bâtiment comme le verre, aluminium, béton armé, ABS, polystyrène dur, laiton, bronze, acier, acier inoxydable, acier galvanisé, carrelage, bois traîté, etc.
Convient parfaitement pour le placement du verre feuilleté.
Peut aussi être appliqué sur des surfaces alcalines comme le béton et la brique. L'application d'un primaire est recommandée dans ce cas.

How it works
The sealant is extruded directly from the cartridge into clean joints using a suitable gun. It cures through reaction with ambient moisture to form an elastic silicone rubber that flexibly seals against air and water infiltration while maintaining strong adhesion on most substrates.
