Features

  • Cabosil Also called fumed silica, it is a hydrophilic silica powder, a lightweight material that is easy to use and can be added to any application
  • Thickener - Thickening powder for epoxy, silicone, paints, varnishes, and liquids significantly increases the viscosity of the liquid and produces a non-sagging property.
  • Strong Adhesive - Fumed silica has strong stability, making it easy to strengthen gel coat, epoxy, polyester, paint and so on. It is also used to make ceramic blanket rigidizer.
  • Multi Usage Cabosil is suitable for thickening epoxy resin. Additionally, it is suitable for rubber reinforcement, and can also be combined with fillers or fibers to prevent them from sagging.

  • Cab-o-stole my heart
Wish i could give this 11 stars, great epoxy thickener. Adds lots of structure and great price. Unless you are trying to 16ft boat worth of thick viscous paste, you'll never need more than a quart

  • Great thickening agent for gel coat/resin
This stuff works great for thickening gel coat or fiberglass to make it more like filler consistency.

  • Great for controlling Paraloid B-72 film properties
This stuff mixed well with a Paraloid B-72 solution for fossil preservation. Highly recommend it!

  • Thickens
This thickens epoxy well. But to get it into a paste, you will go through this extremely fast. If you only add a bit, like 5%, it won't really increase the sandable quality enough.

On time and a d good price

  • Epoxy potting of electric motor stator...
Useful for potting an electric motor stator in epoxy resin for optimal heat exchange, preservation of hardened resin integrity and waterproofing. WEAR a good facemask to avoid breathing this extremely fine ground product!

  • Good additive
Made my epoxy work sooo much better. The first time i used epoxy, it was very runny. If i had experience, i would have had it earlier.

  • Good for repairs
Works will gel coat to make a much easier repair of fiberglass boats.
