WACKER PRIMER G790 TF 20kg – Primer for Improving the Adhesion of RTV Silicones to Surfaces

WACKER PRIMER G790 TF (Toluene Free) is a high-quality, solvent-based adhesion primer developed to significantly enhance the bonding of addition-cure RTV-2 silicones and LSR elastomers to a wide range of substrates. It serves as a key component in processes where a durable, reliable, and reproducible bond between silicone and the base material is essential.

The product forms a thin, uniform bonding layer on the surface that effectively activates the substrate and enables long-lasting adhesion with the silicone during the curing process. This significantly reduces the risk of delamination, material migration, or loss of sealing over prolonged use. Primer G 790 TF is designed for industrial applications where process stability and predictable end results are critical.

Its toluene-free and aromatic solvent-free formulation enhances safety and facilitates integration with modern production processes. The primer can be applied by brush, dip, or spray, allowing easy adaptation to different technologies and production scales—from precise manual applications to automated assembly lines.

WACKER G790TF is highly effective on a wide range of substrates, including metals, glass, ceramics, and selected plastics. It is especially recommended for electronics, electrical engineering, cable accessories, insulators, encapsulated and molded components—applications where the durability of the silicone-to-substrate bond is crucial for the reliability of the overall system.
