Matting powder is a common chemical product in our lives. So what are its production methods? Let's take a closer look.
First, dry mix powder coatings with different curing speeds to mix them so that the gloss of the resulting coating film is significantly reduced, and
then the matting effect is achieved.
Adding cellulose acetate to epoxy powder coatings and adding fine powdered low molecular weight polyethylene and polypropylene resins to
polyester powder coatings can produce matting powder coatings. The gloss of the coating film is affected by manufacturing conditions. Because
the addition of thermoplastic resins will affect the storage stability of powder coatings, the addition amount is limited to 2-3% of the resin amount.
Use a special Curing Agent with matting effect and add fillers with matting effect. Adding fillers such as ultrafine silica and talcum powder significantly
reduces the gloss. In particular, the particle size of the filler has a great influence on the gloss of the coating film. The larger the particle size, the lower
the gloss. It should be noted that increasing the amount of filler will reduce the flatness and mechanical strength of the coating film. In epoxy powder
coatings, the effect of calcium carbonate particle size on the gloss of the coating film is shown in the table. Adding ultrafine silica and kaolin to acrylic
and polyester powder coatings can produce matte coatings. In addition, adding waxy substances such as polyethylene paraffin and hydrogenated
castor oil can also produce matte coatings.
SL-712 Silica Matting Agent is synthetic amorphous silica appearing as white powder.
