我们讲到滑石粉有很多优点所以滑石粉在填充涂料的时候会起到很多作用。
具体都有哪些作用呢？
在涂料中，滑石粉作为填料可以起到骨架的作用，降低制造成本，提高涂膜硬度。具有白度高、粒度均匀分散性强的特点。
滑石粉的片状结构可以使涂层具有较高的耐水性和防渗透性，滑石粉颗粒的片状结构，可以使涂层的流变性能得到很好的改善，同时可以提高涂层的耐候性。
滑石粉主要用于底漆和中间涂层，许多产品和速干底漆优先选用滑石粉。钢结构底漆可以全部或部分使用滑石粉，以提高涂层机械性和耐腐蚀性。
We talked about talc has a lot of advantages so talc is going to do a lot of things when it comes to filling paint.
What exactly does it do?
Talc powder has good suspension and dispersion, corrosion resistance.
In coating, talc powder as filler can play the role of skeleton, reduce manufacturing cost, improve the hardness of coating film. It has the characteristics of high whiteness, uniform particle size and strong dispersion.
The flake structure of talc can make the coating have high water resistance and permeability resistance. The flake structure of talc particles can improve the rheological property of the coating and the weatherability of the coating.
Talc is mainly used for primers and intermediate coats, and is preferred for many products and quick-drying primers. Steel structure primer can be used in whole or in part talcum powder to improve the mechanical properties and corrosion resistance of the coating.
