Silica / Aerosil 200 / Thixotropic powder
About the product
AEROSIL 200 is a hydrophilic fumed silica with a specific surface area of 200 m²/g.Silica can be used as a filler or reinforcing material in composites for the manufacture of surfboards. In combination with resins such as epoxy or polyester resins, silica can help to improve the strength and durability of the surfboard by adding stiffness to the material. Surfboard applications: fin plugs, sealing and repairs.
The concept resin with silica is a universally applicable material mix that is used for EPS blanks and also for our Agave blanks to seal air chambers or grains. Further information on the process can be found in the video.
Lightweight construction:
Silica can also help reduce the weight of surfboards, especially when used as a filler in lighter foam cores or agave blanks. Lighter surfboards have better flex characteristics and offer better maneuverability. Therefore, it is an important part of the sealing process.
Silica-based materials such as epoxy resin are often used for surfboard repairs. These materials can be mixed with silica powder to form a viscous paste that can effectively repair cracks and damage to the surfboard. Silica, also known as thixotropic powder, acts as a thickening agent due to its angular structure, which in high consistens turns resins into a kind of filler and thus prevents the compound from running away.
Silica (quartz sand) is transulent in itself and can add turbidity in large quantities.

Sustainability
Why is this product a SUSTAINABLE PRODUCT?
Evonik's aerosil 200 (silica) is produced in Germany and is considered the most sustainable thickening agent on the market to date. Products made using Aerosil 200 have a longer shelf life because it is (quartz sand) silicon, which gives the mixed mass a little more strength.
