Sag Resistance Function of Fumed Silica In Polyurethane Coating
experiment process
Apply sample A and B onto tinplate by paint film preparer respectively
Sample B without HIFULL fumed silica drips and shows uneven film thickness
While sample A added HIFULL fumed silica performs good anti-sagging properties
prevents excess paint on the edges or drips when applying paint.
Experiment conclusion: Fumed silica greatly improves the anti-sagging performance of two-component polyurethane coatings
