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.
Silica is available in a variety of sizes:
One 1/2 gallon (#23-A)
One carton (#23-B)
One bag (#23-C)
