Wacker Fumed Silica N20Fumed Silica N20
Product Description: Wacker Fumed Silica N20 is a synthetic hydrophilic amorphous silica, produced by flame hydrolysis as a high-purity white powder. It is mainly used in silicone rubber (HTV, RTV), resin coatings, paints, inks, electronics, papermaking, pharmaceuticals, cosmetics, toothpaste, adhesives, plastics, and other industries. Its characteristics include excellent anti-settling, anti-sagging, thickening and thixotropic properties, anti-sedimentation, improved dielectric properties, and promotion of free flow. It is an effective free-flow aid, external control agent for positive and negative systems, carrier for active components (such as catalysts), granulation aid, processing aid, anti-caking agent, and stabilizer.
Wacker Fumed Silica N20Applications:
● Unsaturated Polyester: Laminating resins, gel coats, grout mixtures, polar resins (epoxy, vinyl resin series)
● PVC: Plastisols, organosols, flexible PVC compounds, cable compounds, dry blends, films and sheets, etc.
● Printing Inks: Letterpress, gravure, screen, flexographic, offset printing inks
● Paints and Coatings: Epoxy and polyurethane coatings, alkyd resin coatings, acrylic resin coatings, zinc-rich coatings, powder coatings, etc.
● Sealants and Adhesives: Polychloroprene-based, epoxy, polyurethane resin, cyanoacrylate-based, emulsion-based, etc.
● Insulating Compounds: Cable compounds, insulating filling compounds for optical cables
Wacker Fumed Silica N20Characteristics:
● Controls rheology and thixotropy of liquid systems, adhesives, polymers, etc.
● Acts as an anti-settling, thickening, and anti-sagging agent
● Reinforces HCR high-temperature vulcanized silicone rubber and RTV-2K two-component room-temperature vulcanized silicone rubber
● Improves powder properties, enhances flowability and anti-caking
