VANSIL® Wollastonite is a high brightness mineral filler and functional extender pigment for paint. Its relatively high pH (10-11) helps maintain the pH of latex paints in the desired range of 8-9. Both high aspect ratio and low aspect ratio grades are available.
Product | Description | Benefits | Applications |
---|---|---|---|
Vansil® HR-1500 | Vansil® HR-1500 is a Wollastonite (Calcium metasilicate). | Short-needle, high aspect ratio wollastonite (3¼ Hegman fineness). It has low binder demand and low water solubility. | Used in high build coatings such as texture paints and mastics to improve mud crack resistance and give film reinforcement. |
Vansil® HR-2000 | Vansil® HR-2000 is a Wollastonite (Calcium metasilicate). | Short-needle, high aspect ratio wollastonite (0-1 Hegman fineness). It has low binder demand and low water solubility. | Used in high build coatings such as texture paints and mastics to improve mud crack resistance and give film reinforcement |
Vansil® W-10 | Vansil® W-10 is a Wollastonite (Calcium metasilicate). | Coarse grade of wollastonite with approximately 20% retained on a 325 mesh sieve. It has low binder demand and low water solubility. | Useful as an extender in high build coatings such as block fillers and texture paints. |
Vansil® W-20 | Vansil® W-20 is a Wollastonite (Calcium metasilicate). | A relatively coarse (1 Hegman fineness) low aspect ratio grade of wollastonite. It has low binder demand and low water solubility. | Used as a general purpose extender pigment where ultra-fineness is not required such as texture paints and block fillers. |
Vansil® W-30 | Vansil® W-30 is a Wollastonite (Calcium metasilicate). | A medium fineness (4 Hegman fineness) low aspect ratio grade of wollastonite. It has low binder demand and low water solubility. | Used as a general-purpose mineral filler in a wide range of liquid coatings and powder coatings. May be used as a TiO2 spacer and extender. |
Vansil® W-40 | Vansil® W-40 is a Wollastonite (Calcium metasilicate). | Fine particle (5 Hegman fineness) low aspect ratio grade of wollastonite. It has low binder demand and low water solubility. | Used as a general-purpose mineral filler in a wide range of paint and coatings. It is used as a TiO2 spacer and extender. |
Vansil® W-50 | Vansil® W-50 is a Wollastonite (Calcium metasilicate). | The finest of the low aspect ratio grades of VANSIL (6+ Hegman fineness). It has low binder demand and low water solubility. | Used for liquid industrial and corrosion resistant coatings, powder coatings and semi-gloss architectural coatings. In powder coatings, this grade is desirable for smoother films and improved gloss. |
Vansil® WG | Vansil® WG is a Wollastonite (Calcium metasilicate). | Relatively coarse particle, high aspect ratio wollastonite. It has low binder demand and low water solubility. | Used in high build coatings such as texture paints and mastics to improve mud crack resistance and give film reinforcement |
Product and customer insights
Despite numerous cleanings, the productivity of the Reverse Osmosis plant would not recover from severe membrane fouling. The membrane autopsy revealed that the ferric hydroxide was seeding
silica polymerization and that even while the ferric hydroxide was removed, the silica scaling was continuing to grow.
The plant was experiencing weekly shutdowns for fiber clean up (~ 3 kg bags of matted slurry is cleaned per week). The shut downs were costly as they reduce plant availability for production.
The International Maritime Organisation (IMO) regulation, known as IMO 2020 was the the largest change in regulation relating to marine fuels impacting 75% of the fuel used by the shipping industry.
