When grouting on vertical or overhead surfaces, it is important to prevent issues such as flow and dripping. Fumed silica can help address this problem.
- Add 5.7% hydrophobic fumed silica to AB component epoxy grout sealant;
- fully disperse with a high-speed disperser as an experiment sample;
- Take another AB component epoxy grout without adding fumed silica as a blank sample;
- Put the experiment sample into the packaging tube;
- use a glue gun to squeeze onto the flow leveling tester;
- scraped on steel plate;
- Carry out the same process for the blank sample;
- After scraping, place the two steel tinplates straight up;
- The experiment sample added HIFULL fumed silica performs good anti-sagging properties;
- While the blank sample without HIFULL fumed silica is dripping down.
The above experiment shows that HIFULL Fumed silica can effectively enhance the epoxy grout’s resistance to dripping.
