(과제) 테트라플루오로에틸렌계 폴리머와 소정의 폴리옥시알킬렌 변성 폴리디메틸실록산과 액상 분산매를 포함하는 파우더 분산액, 그리고, 테트라플루오로에틸렌계 폴리머의 물성을 고도로 구비한 소성물을 갖는 복합체의 제공. (해결 수단) 본 발명의 파우더 분산액은, 테트라플루오로에틸렌계 폴리머의 파우더와, 액상 분산매와, 중량 평균 분자량이 3000 이하이고, 또한, Griffin 식으로부터 산출되는 HLB 값이 1 내지 18 인 폴리옥시알킬렌 변성 폴리디메틸실록산을 포함한다. 본 발명의 복합체는, 본 발명의 파우더 분산액을 표면에 부여하여 가열하여 제조할 수 있다. [Object] To provide a powder dispersion comprising a tetrafluoroethylene polymer, a particular polyoxyalkylene-modified polydimethylsiloxane and a liquid dispersion medium, and a composite having a baked product having physical properties intrinsic to the tetrafluoroethylene polymer. [Solution] The powder dispersion of the present invention comprises a powder of a tetrafluorethylene polymer, a liquid dispersion medium and a polyoxyalkylene-modified polydimethylsiloxane having a weight average molecular weight of at most 3,000 and an HLB value of from 1 to 18 calculated by Griffin's equation The composite of the present invention is produced by applying the powder dispersion of the present invention to the surface of a substrate and heating the powder dispersion.
