The contact angles of several batchs of F2314 solution and other fluoropolymer solution to 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) pellet were measured by TY-82 contact angle instrument. The results show that the contact angles on TATB are small to the solution of the copolymer of difluoroethylene and hexafluoropropene F₂₆₀₂，F₂₆₀₃. To the copolymer of difluoroethylene and trifluorochloroethylene F₂₃₁₄,the contact angles vary with the change of the batch when the solution content is 8%,at the same time the contact angles will decrease when the solution content is lowered. F₂₃₁₄ solution has good soaking effect on TATB when butyl acetate is used as solvent.
