Nano silica for coating

  Nano silica (  ug-sp50t ) ■ general
UG-SP50t  It is widely used in solid and liquid silicone rubber, paint, coating, ink, resin, adhesive, rubber and plastic film, color masterbatch, cable material, resin FRP products, composite materials, electronic products, cosmetics, pharmaceuticals and other fields

■ product characteristics
1
In the silicone rubber products, it plays the role of strengthening, wear resistance, high temperature resistance, tear resistance and improving dielectric properties

2
In paint, coating and ink products, it plays the role of thickening, thixotropy, extinction, dispersion, anti sedimentation, anti caking, anti sagging, improving stability, adjusting water content, optimizing free flow and electrostatic application
3
In adhesive products, it plays the role of reinforcement, thickening, thixotropy, anti sedimentation, anti caking, processing aids, improving stability and adhesion

4
It plays the role of anti sagging, anti-aging, anti impact, improving strength and improving the smoothness of the surface in resin FRP products and composite products
5
In plastic film products, it can resist aging, impact, prevent foaming polyester cracking, and improve strength and transparency
