Silicone primers provide an active surface for silicone OH bridges. This active surface then gives a better possible adhesion for silicone. For non-absorbent surfaces it is very important that the primer for silicone is applied very thinly. In principle, the layer should be practically 1 molecule thick. Otherwise the bond...
The mixture forms a rigid film of silicone resin when exposed to humidity at ambient or elevated temperature and adheres firmly to the substrate. The catalyzed silicone rubber applied to it then forms a tight bond with this resin film...
ELASTOSIL® AUX G 3243 is a solution of a siloxanes and reactive silanes in organic solvents. It is used to pretreat metallic, ceramic, glass or other polymeric substrate surfaces to enable excellent adhesion towards subsequently vulcanized ELASTOSIL® R solid silicone elastomers (HCR/HTV, peroxide...
WACKER® PRIMER G 790 TOLUENE FREE is free of toluene and free of other aromatic solvents. This primer G790 is suitable for all addition curing silicone (Silicone Addition ...) and condensation curing silicones in our webshop. This primer increases the...
WACKER® PRIMER G 791 A/B is a two-component, addition-curing primering system diluted in an organic solvent. The primer is applied to the substrate and after curing forms a primer film which firmly adheres to the substrate. Application of a silicone...
This primer G795 is suitable for all addition curing silicone (Silicone Addition ...) and condensation curing silicones in our webshop. This primer increases the adhesion between the surface and the silicone poured opon it. Most addition curing silicone does not...
Silicone primers provide an active surface for silicone OH bridges. This active surface then gives a better possible adhesion for silicone.
For non-absorbent surfaces it is very important that the primer for silicone is applied very thinly. In principle, the layer should be practically 1 molecule thick. Otherwise the bond will lose strength.
For absorbent surfaces most primers need to be applied sufficiently. Viscous primers are of course more suitable for such surfaces than thin ones.
The Primer AV, for example, can be used well on wood and also has a long working time.
Here you will find a short overview of the different primers for silicone we have to offer:
