NON-STICK COATING SYSTEM WITH PTFE AND PFA OR FEP FOR CONCENTRATION GRADIENT |
| 摘要 |
Improved non-stick coating systems can be applied to untreated smooth substrate with a primer of a polytetrafluoroethylene having a melt viscosity over 10<10>Pa Sec plus a copolymer of tetrafluoroethylene with hexafluoropropylene or perfluoro alkyl vinyl ether with the melt viscosity of the polytetrafluoroethylene being at least 10<2>Pa Sec higher than that of the copolymer to give a concentration gradient. |
