분산 코팅 제형에서의 분산 점도를 감소시키는 방법이 개시된다. 상기 방법은 상기 제형 중의 종래의 PVDF의 일부를 고결정성 PVDF로 대체하는 단계를 포함한다. 고결정성 PVDF는 (X선 회절로부터) 결정도가 44% 이상이다. 고결정성 PVDF는 코팅 분산 제형에 낮은 점도를 부여한다. A method of reducing dispersion viscosity in a dispersion coating formulation is disclosed. The method comprises substituting a portion of the conventional PVDF in the formulation with a highly crystalline PVDF. The highly crystalline PVDF has a crystallinity 44% or greater (from X-ray diffraction). The highly crystalline PVDF imparts lower viscosity to the coating dispersion formulation.
