Epoxy Resin Filler

We offer a wide range of epoxy resin filler powders for a variety of end uses - fine epoxy fillers for fairing, hollow spheres to increase the volume and reduce the density of a resin system, microfibres for adding strength, and flow modifiers to thicken mixes.

Hollow spheres

  • add volume
  • reduce density
  • for making (low strain) adhesives, and filling & fairing mixes

Types

Microballoons. Phenolic resin spheres, brown in colour. Easy to apply, easy to sand.

Glass bubbles (Glasscell 25). White glass microballoons, better abrasion resistance than phenolic microballoons. Good density/compression resistance.

Glass bubbles (Glasscell 10). Ultralight version of Glasscell 25.

Short fibres (microfibres)

  • a resin filler to add strength
  • for making structural adhesives

Types

Wood-cellulose fibres (Treecell) - for making structural adhesives, or high-density radius or fillet joints, white in colour.

 

Flow modifiers

  • very fine powder to thicken resin
  • thickens mixes and reduces their flow on vertical surfaces (increase thixotropy)
  • increases initial adherance (tack)
  • can be used with other fillers

Type

Fumed Colloidal Silica (Sillicell). White in colour.
