Finely milled E-glass fibres (0.2 mm) for reinforcing
adhesive, filling and moulding compounds.
Suitable for epoxy, polyester and vinyl ester resins.
Fast and easy wet-out.
Milled Glass Fibres are fine, short E-glass fibres
used to reinforce synthetic resin mixtures.
They enable the production of fibre-reinforced
adhesive, filling and moulding compounds
and can improve their mechanical properties.
With a nominal fibre length of 0.2 mm, they can be
distributed evenly throughout resin systems.
The silane-based sizing supports wet-out and
bonding between the fibres and resin matrix.

Temperature and resistance data refer to the glass
fibre material. The properties and permissible
service temperatures of cured moulding compounds
depend on the resin system used.
Benefits
- Fast and easy wet-out with suitable synthetic resins
- Suitable for epoxy, polyester and vinyl ester resins
- Fine fibre reinforcement of adhesive, filling and moulding compounds
- Uniform incorporation due to the short fibre length
- Good chemical and thermal resistance of the glass fibre material
Typical Applications
- Fibre-reinforced filling and adhesive compounds
- Compression moulding compounds and moulded parts
- Resin-based plasters and putties
- Corrosion protection coatings
- Filling and repair compounds in boatbuilding and model making
- Fibre reinforcement as a substitute for asbestos in suitable formulations
Processing
For two-component systems, first thoroughly mix the
resin and hardener according to the specified mixing
ratio. Then gradually add the milled glass fibres
while stirring until they are evenly distributed.
The amount added depends on the resin system,
processing method and desired consistency.
For non-sagging adhesive and filling compounds,
suitable fillers or thixotropic agents may be added.
A trial mixture is recommended.
