Primers for silicones

One of the advantages of silicone is that it adheres to less smooth surfaces. However, if this is the intention, we often recommend the use of a primer. Here you will find several silicone primers.

          Primers for silicones

          Silicone primers provide an active surface for silicone OH bridges. This active surface then gives a better possible adhesion for silicone.

          It is very important that the primer for silicone is applied extremely thinly. In principle, the layer should be practically 1 molecule thick. Otherwise the bond will lose strength.
