Feature(may vary by option.)
●Hydrophilic fumed silica, also known as cabosil or colloidal silica, is a thixotropic additive thickening agent that lets you customize the viscosity of epoxy, polyester resin, paint and more
●Epoxy thickened with this fine silica powder won’t sag or slump, ideal for vertical and overhead surfaces. Easy to stir into mixed resin and hardener, and easy to sand upon full cure
●It creates a smooth, strong epoxy compound ideal for bonding, filleting, and filling. Epoxy or polyester resin thickened with silica can be used to fill holes, cracks, and gaps
●Combine this versatile filler with TotalBoat epoxy and Glass Micro Balloons or Milled Glass Fibers for easy sanding and additional strength
●Use with gelcoat, paints, acrylics, silicones, rubber, urethanes, adhesives and other materials to prevent sagging. Available in 1 Quart and 5 Quart sizes

Description
TotalBoat Silica Thickener is an extremely fine micron thickening powder. Also called Cabosil or fumed silica, it’s mostly (but not exclusively) used as a thickening agent or additive for epoxy resin and polyester resin. When added to mixed resin components, it creates a smooth, peanut-butter consistency compound or putty that won’t sag when applied to vertical or overhead surfaces. Epoxy thickened with fumed silica makes a great bonding and filleting adhesive, and is ideal for filling cracks, gaps, holes, and voids.
Use alone or combine with other fillers. Example: after blending with mixed resin and harder, add TotalBoat Glass Microballoons to create an easy-to-sand fairing compound. Or, add TotalBoat Milled Glass Fibers for even more strength and sag resistance. Epoxy mixed with TotalBoat Silica Thickener cures extremely hard and abrasion resistant. This thixotropic thickening agent can also be used with paint, gelcoat, silicones, acrylics and other materials. Perfect for resin art and crafting.
Tips: Always mix a small trial batch of resin and additives to fine tune viscosity, and to assess any impact to epoxy working properties (pot life). Always wear proper safety protection when working with epoxy resin and fillers / additives. Be sure to wash your hands and any exposed skin thoroughly with soap and water afterwards. Compare to West System 406 filler, System Three White Silica Thickener, Cab-O-SIL, and others. All TotalBoat products are formulated for great results and great value. When it comes to epoxy, we know what works.
