Techsil Silicone Ink is a one-component, flowable, heat curing ink, which offers primer less adhesion to a wide variety of substrates. When using on difficult to bond substrates, or a more aggressive chemical bond is required, SS4155 can be used to enhance adhesion. 20% (by weight) of blue silicone pigment has been added to the TSI to give its color density. Techsil® Silicone Ink contains no solvent and is a one component product, meaning there is no mixing required. It offers a fast cure at elevated temperatures, and gives no cure by-products. It is non-corrosive to metals and sensitive substrates and offers excellent dielectric properties.
