NuSil silicone primers help to ensure the effectiveness and long-lasting performance of silicone adhesives by preparing a substrate surface for adhesive application. They also aid in adhering to materials with low surface energy by activating the surface to provide the best bond possible.

The NuSil portfolio of silicone primers has been developed to help improve adhesion for a wide range of substrates: silicone, metals such as aluminum, stainless steel and titanium and a wide range of plastics and rubbers, including polytetrafluoroethylene, polycarbonate, polyurethane, polyimide, ABS, PEEK and polysulphone.

Our extensive line of silicone primers is moisture-sensitive and time-dependent: they will react to moisture in the air, and it is typically recommended that they cure for 10-15 minutes before a silicone adhesive is applied. They can be applied through a variety of methods including spraying, wiping, brushing or dipping.

NuSil can collaborate with you to assess the surface properties of your substrate and recommend both the best silicone adhesive and best silicone primer to work with your production processes and the devices you are manufacturing.
