    摘要： The present invention provides a two-layer coating system for coating substrates selected from the group consisting of PMMA, PC, PET, and PS comprising an upper layer selected from the group consisting of:

    a) poly(TFE/HFP) and poly(VF 2 /TFE/HFP), wherein the molar ratio of HFP to TFE is between about 0.9 and 1.9 and, in the case of the VF 2 /TFE/HFP terpolymer, the concentration of VF 2 is about 19 mole %; and
    b) poly(TFE/perfluoro-2,2-dimethyldioxole) wherein the concentration of the perfluorodimethyldioxole is between 60 and 90 mole %;
    and a lower coating layer selected from the group consisting of:

    a) poly(VF 2 /TFE/HFP) wherein the ratio of TFE to HFP is between about 0.9 and 1.9 and the concentration of VF 2 is between about 18 and 60% on PMMA substrates and between about 12 and 40 mole % on PC, PET, and PS substrates;
