with eva formulated for encapsulant another approach to forming a polyvinylidene fluoride outer layer is by coating with a solvent or aqueous based coating a fluoropolymer layer as a solvent coating based on pvdf or pvdf copolymers may be applied by known means onto a pet layer surprisingly adhesion of the coating is very good optionally the surface of the pet could be treated to enhance adhesion via addition of a primer with or without a high energy surface pre treatment corona or plasma the formulation could include 0 to 30 by weight of mineral filler such as ti02 acrylic polymers stabilizers and other additives the melting point of the pvdf can be from room temperature to 150 u00b0 c for low temperature melting point polymers u2014 the thermal resistance of these coatings to future pv module lamination conditions 150 c for 5 minutes can be improved by optionally formulating a cross linked formulation an aqueous based polyvinylidene fluoride can be applied via a latex coating based upon our acrylic modified fluoropolymer and coated onto a pet or other substrate adhesion of the acrylic modified polymer is surprisingly very good optionally the surface of the pet could be treated to enhance adhesion via addition of a primer with or without a high energy surface pre treatment corona or plasma the formulation would include additives u2014 as in the solvent coating coating could also contain functional comonomers such as hema having a hydroxyl equivalent of between 10 and 100 and most preferably 20 and 80 the coating resin content contains 50 to 100 of vf2 based polymer 10 to 50 of functional acrylic monomer the coating can further contain 0 to 30 mineral filler 0 to 7 stabilizers and process aides.
