Product Information


A non-flowable, paste product Novagard RTV 400-150 presents an excellent balance between rate of cure, adhesion, and physical properties. It has a lower odour than conventional acetoxy-cured silicones.


Novagard RTV 400-150 functions as an adhesive sealant, which develops a bond to most common substrates without the use of a primer. This ready-to-use, single-component compound is typically used as an adhesive to bond dissimilar materials, as a sealant for creating formed-in-place gaskets, or a multitude of other applications. The service temperature is -40°C to 205°C.
