Product Features
TD 1017 is fine particle hydrophobic silica.
TD 1017 contains larger than 2 % chemically bound carbon and is therefore not wettable by water .
The wettibility of TD 1017 with methanol is approx . 55 % and
indicates its highly hydrophobic character.

TD 1017 can be used as anti-caking agent and is also suitable to be used in a great variety of defoamer .
Applicatioη
Defoamer,antifoaming agent
Fire extinguishing powders (anticaking)
Masking powders for chill casting
Chemicals (flowability,anticaking)
HTV/RTV-2C/LSR silicone rubber (reinforcing filler)
