Cab-O-Sil Thixotropic Resin Thickener
Cab-O-Sil, also known as Aerosil is a thickening agent for epoxies, polyesters, and urethanes. Thicken resins to your own taste by adding varying amounts.
Ideal for making adhesives and putties for gluing wood, fiberglass, stone, concrete, etc. However, adding this product will make the cured resin a bit more difficult to sand.
Typically used for leash plug and finbox installs, filling gaps in foam for ding repairs. Also can be added to epoxy resin to seal EPS blanks for additional strength.
