How to choose aluminum pigments(图1)
Aluminum pigment is a kind of metallic pigment, the material is aluminum, auxiliary and wetting agent. The special water-based aluminum paste contains a certain amount of silica, and the resin-coated aluminum paste contains special resin materials. The effects and functions of different aluminum pigments will be very different. Aluminum pigments are more defined as "effect pigments" in coatings, and more of the metallic texture is reflected in the coating system, and only a few scenarios will use the weather resistance, acid and alkali resistance of aluminum pigments.
When choosing a scene anti-corrosion type application, this application pursues two directions-a beautiful appearance, a certain anti-corrosion ability, and heavy-duty anti-corrosion applications that do not consider the appearance. The beautiful appearance is more using leafing aluminum paste to create a bright silver color effect, which is similar to the effect of galvanizing, but does not have long weather resistance; and more heavy-duty anti-corrosion uses non-leafing aluminum Paste, use the adhesion and recoating performance of this type of product, so as to achieve the corresponding anti-corrosion ability.

When choosing the application of plastic paint and metal baking varnish, plastic paint pursues more beautiful texture and decorative effect, so in this respect, aluminum paste can only provide beautiful metallic feeling and better brightness, but The scratch resistance, hardness and adhesion of the coating have nothing to do with the product. Of course, there are special situations, such as applications requiring acid and alkali resistance, sweat resistance, and insulation properties.
Choose the aluminum paste related to the application in order to make the matching effect and function. The slight deviation in the selection will bring unexpected differences. We hope that the majority of users will communicate with professional industry practitioners when choosing aluminum paste. And communicate, so as to use aluminum paste products that match your actual situation.
