Fillite filler / hollow microspheres

Filler made of aluminium silicates for epoxy, polyurethane, polyester & acrylic resins, silicone, plaster, concrete, cement, etc.

Fillite consists of low-density ceramic filler / hollow microspheres. This very light filler can be used to thicken casting resins, for example, to produce pastes and coating compounds. By adding Fillite microspheres, you also obtain a lighter casting or lighter casting moulds and you need less casting resin for the same volume, for example. The addition of Fillite also reduces shrinkage.

Fillite is suitable as a filler for various materials such as epoxy resins, polyurethane resins (PUR), polyester resins, acrylic resins, silicone, plaster, concrete and cement. Due to its stable hollow structure, Fillite can be sanded very well, e.g. with metalworking tools. Fillite is waterproof in combination with casting resins.

APPLICATION

As it is very important which casting resin or casting compound of which consistency is used and how solid or liquid the resulting casting or filling compound should be, we can only give rough advice on the mixing ratio. We recommend gradually filling the resin or casting compound with Fillite until the desired consistency is achieved. Before mixing large quantities of material, do a trial with a small amount.

For rough orientation:

Mixing ratio for casting resins: 50 - 80 parts by weight Fillite per 100 parts by weight resin
Mixing ratio for fillers & pastes: 150 - 300 parts by weight Fillite per 100 parts resin

The relatively high density of the product ensures limited dust formation during mixing. However, it is recommended to work with a dust extraction system or a suitable fine dust mask. The use of a suitable fine dust mask is also required when further processing the cured product, e.g. sanding.
