- Adhesion preparation for addition-curing silicones (RTV-2, LSR) on metal, glass and plastics
- Pretreatment of metals before bonding with acetic-curing one-component silicones: better adhesion and protection against corrosion
- Very thin coats by spraying thanks to its very low viscosity (approx. 1 mm²/s); dipping or brushing also possible
Suitable for: Electronic potting, moulded parts and silicone-metal composites
Frequently asked questions
What is the advantage of the TF version?
G 790 TF is free of toluene and aromatics, making it more pleasant to work with, while being just as universally applicable.
How do I achieve the best adhesion on metal?
Prepare a clean, dry and grease-free surface and roughen very smooth surfaces. Apply the primer thinly and free of bubbles and let it dry for at least 1 hour. Baking at 120–150 °C further improves adhesion on metals.
Which primer suits which silicone?
G 790 TF for addition-curing silicones (RTV-2, LSR), G 718 x for one-component silicones (RTV-1), ELASTOSIL® AUX G 3243 for peroxide-curing solid silicone rubber (HTV).
