Prevent Sags on Vertical Surfaces

A white, free-flowing powder, Thixotropic Silica is a thickening agent primarily added to resin to prevent run-off and sags on vertical surfaces.

  • Use with an epoxy to produce extremely hard, solid parts, perfect for structural bonding, filling, and filleting.
  • Use in conjunction with chopped glass fiber for added strength for parts.
  • Silica-filled resin can be difficult to sand. Consider using #22 Glass Microspheres for areas that require sanding.

This filler is compatible with epoxy, polyester, and vinyl ester resin systems. Add filler after adding catalyst to resin.

Mix ratio is 1:2 (filler to resin by volume) for general use, 1:3 (filler to resin by volume) to reduce runs/sagging.

Fillers, when ordered alone, will typically ship in a small or medium box. Where possible, we will combine ordered items to reduce the number of boxes shipped.
