By coating a substrate, such as glass fiber fabric, with a blend of a perfluoropolymer and a silicone poly­ mer, an adhesive layer can be bonded either directly to the surface of the per­ fluoropolymer composite or to a perfluoropolymer composite that has been primed without the need to have otherwise treated the perfluoropolymer surface, such as either by etching or by the deposition of an intermediate coating contain­ ing colloidal silica or other similar agents, to make the surface bondable. •t i-H 00 FIG. 4 i-H o CJ o & WO 2013/181431 AlllllllH SE, SG, SK, SL, SM, ST, SV, SY, TH, TJ, TM, TN, TR, TT, TZ, UA, UG, US, UZ, VC, VN, ZA, ZM, ZW.
