Longer pieces on the questions that decide a silica trial — how to benchmark against the grade you use now, what surface treatment actually changes, and how to read a fault on the panel. Written the way we would explain it on a call: no specification tables, no equivalence claims.
Untreated matting silica has a bare, water-loving surface; treated grades carry an organic or specialised surface layer added after production. The treatment…
Troubleshooting · Coating Matting & RheologyA milky matt clear coat usually comes from one of five things: the matting agent is scattering light inside the film, the film is too thick, the coating has…
Selection · Oral Care SilicaToothpaste uses two different silicas for two different jobs. Thickening silica builds the structure that holds the paste together, keeps it on the brush and…
Troubleshooting · Coating Matting & RheologyHard settling comes from the matting particles packing tightly at the bottom of a can whose liquid phase cannot hold them apart. The four things that decide it…
Selection · Coating Matting & RheologyPrecipitated and fumed silica are made by different routes and do different jobs in a coating. Precipitated grades are the normal choice for matting: they are…
Troubleshooting · Agrochemical CarrierA water-dispersible granule that will not break up in the spray tank has usually been made too strong: too much binder, too much compaction, or a carrier that…
The material you use now, the formulation or resin, the equipment and the target you need to hit. That is enough for us to say whether we have something worth testing.
