Fillers

The properties of the resins are changed by fillers, e.g. mechanical properties such as hardness, thermal shock resistance, dimensional stability, flow and processing properties and abrasion resistance are improved.

  • Glass fibre chips are used for the production of fibre-reinforced filling, bonding and pressing compounds.
  • Microballs hollow glass microspheres are used to create light, easily grindable fillers and coves. Inorganic hollow microspheres are also used to reduce the weight of resin layers.
  • Microflocks cotton flocks are used for the production of fillers and adhesives, as well as for coupling layers in mould making.
  • Thixotropic agent is used for the production of non-leaking topcoat resins and for the production of fillers and adhesives.
  • Paraffin solution can be added to the laminating resin or gelcoat to achieve a tack-free curing surface.


Our selection of fillers for synthetic resins offers a wide range of options suitable for various applications in the field of glass fiber reinforced plastics. All fillers are combined with epoxy resin or polyester resin. It is important to note that the amount added varies depending on the product and is specified in the product description.

  1. Glass fiber chips are used to manufacture fiber-reinforced fillers, adhesives, and molding compounds.
  2. Microballoons (micro hollow glass spheres) are ideal for producing lightweight, easily sandable fillers and hollow beads. They can also be used to reduce the weight of resin layers.
  3. Microflakes made from cotton are used in the mold-making industry for the production of fillers and adhesives as well as for coupling layers.
  4. Thixotropic agents are used for the production of non-sagging topcoat resins and the production of fillers and adhesives.

Fillers alter the properties of resins, e.g., improving mechanical properties such as hardness, thermal shock resistance, dimensional stability, flow and processing properties, and abrasion resistance.

Adding fillers to synthetic resin can improve the properties of the resin. This applies to mechanical characteristics such as hardness, thermal shock resistance, dimensional stability, flow properties, processability, and abrasion resistance, which can be optimized as a result.

Our selection of fillers for synthetic resins offers a wide range of options that are suitable for various applications in the field of glass fiber reinforced plastics. All fillers are precisely mixed with epoxy resin or polyester resin.

It is important to note that the required amount of additive varies depending on the product and is specified in the product description.

They are ideal for the production of fiber-reinforced fillers, adhesives, and molding compounds and are used in mold making and coupling layers. These materials are suitable for both epoxy resin and polyester resin.

The production of lightweight fillers that are easy to sand and suitable for use in coving is of great importance. Inorganic micro hollow spheres are used to reduce the weight of resin layers. These materials are usually processed with epoxy resin or polyester resin.

Thixotropic agents are used to produce non-flowing topcoat resins or for the production of fillers and adhesives. They are compatible with both epoxy resin and polyester resin.

Cotton fibers are used in the manufacture of fillers, adhesives, and coupling layers in the mold-making industry. They can be used in conjunction with synthetic resins in the field of glass fiber reinforcement.
