Expanded Polytetrafluoroethylene - an overview ...
A topical adhesive on a carrier paper is usually applied to ePTFE joint sealant to facilitate its application on the sealing surface. The paper is peeled at the time of applying the joint sealant to a flange (Fig. 6.44). Overlapping the joint sealant at a point completes the seal. Joint sealant works well with complex flanges and equipment.

Which industrial sealant is right for your application ...
Having a sealant being applied on an incompatible material may result in the degradation of the material and failure to seal off the joint. Porous surfaces: Porous surfaces have the best compatibility with sealants having a high viscosity or gel like texture. Silicone, polymers and epoxies are the best-suited sealants for porous materials.
Users Guide to Adhesives - FreemanSupply.com
Dissimilar materials: Adhesives can join different materials together – materials that may differ in composition, moduli, coefficients of expansion, or thickness. Reduced corrosion: The continuous adhesive bond forms a seal. The joint is consequently leak proof and less prone to corrosion. Electrically insulating: The adhesive bond can provide an
5. External Wall Construction
with the manufacturer's advice to improve the adhesion of the sealant. For effective sealing, the sealant should be extruded against a firm backing, such as a suitable backer rod, so that it is forced against the sides of the joint during application. The applied sealant should not adhere to the backing material because the induced restraint
