### ⭐⭐⭐⭐⭐ 







  
  
    Works great
  

*by S***0 on Reviewed in the United States on 25 July 2024*

Building a mini tugboat. This filler thickens up epoxy resin very quickly. Seems to require a smaller amount than other fillers that I have used. When teh epocy cures, it makes for a very hard surface.

Great product works well

### ⭐⭐⭐⭐⭐ 







  
  
    Excellent for Strengthening Epoxy
  

*by R***Y on Reviewed in the United States on 20 December 2021*

I added the silica to structural epoxy to repair a jet ski hull.  This is an excellent product that mixes well with epoxy and provide strength.  I can tell a significant difference between straight epoxy, and, epoxy mixed with silica.  The straight epoxy sands very easily, but the silica epoxy takes several more passes for same results.  It's easy to mix the silica into the epoxy, and I can guarantee you will not put in too much silica.
