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.
Siliconen Primer Wacker G790
€ 89,54 € 74,- Excl. tax
✔ Increases the adhesion between addition silicone and various surfacesCompare
✔ Functions on metals, wood, various plastics
✔ Soluble in white spirit or alcohol
Primer ELASTOSIL® AUX G 3243
€ 108,90 € 90,- Excl. tax
✔ Provides excellent adhesion onto various substrates.Compare
✔ Solvent based
✔ Various application methods (e.g. coating, dipping, brushing, spraying)
✔ Further dilution in organic solvents possible
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.
