Quarzwerke High Performance Fillers for wood coatings, floor varnishes and laminates
- appear transparent in varnishes
- enable greater filling power without smearing
- make it possible to adjust the gloss as desired
- create very hard surfaces
- improve resistance to abrasion and scratching
- are highly dispersible

The functional fillers SEPASIL® EK, SEPASIL® QM and MINEX® have many effects and benefits, most of which are recommendable for the bonding systems used in wood coatings, floor varnish and laminates.
Tests were conducted to determine how various filler parameters including dispersion of grains, surface texture and treatment, and filling power affect the coating.
The following criteria were observed:
- Abrasion resistance
- Scratch resistance
- Gloss
- Transparency
- Haze
SEPASIL® white corundum and SEPASIL® silica flour: for melamine resins
The use of surface-modified SEPASIL® corundum and silica flour:
- increases the scratch resistance and abrasion resistance of melamine resin coatings
- offers greater filling power while maintaining transparency
- lower costs when SEPASIL® quartz flours are used in combination with the corundum products normally in use.
SEPASIL® white corundum and MINEX® nepheline syenite: for aqueous 2K PU systems
The use of surface-modified SEPASIL® white corundum and MINEX® nepheline syenite:
- achieves excellent transparency and improved scratch resistance
- increases the proportion of solid particles in varnishes
- varying the proportion of fillers makes it possible to achieve the desired surface characteristics – particularly the degree of gloss/matte.
SEPASIL® white corundum and MINEX® nepheline syenite: for aqueous UV systems
The use of surface-modified SEPASIL® white corundum and MINEX® nepheline syenite:
- achieves excellent transparency, abrasion resistance and improved scratch resistance
- increases the proportion of solid particles in varnishes
