Fumed Silica Increases The Adhesion Of Acrylic Coating
experiment process
Crosscut the two acrylic topcoat samples
Stick 3M tape onto the scratched area
Pull off the tape with force
Check the appearance
The detached area of Sample B is way more than Sample A
Experiment conclusion: Fumed silica increases the adhesion of acrylic topcoat, improves their resistance from substrates.

When fumed silica is used as filler or additives, it helps in thickening, reinforcement, transparency, free-flow, thixotropic performance, dielectric properties, anti-settling, heat insulation, and anti-sagging. For example, for powder products, HIFULL fumed silica is used as an anti-caking agent; for liquid products, HIFULL fumed silica is used as an anti-settling agent or suspending agent.
