Abstract
Filler mixtures containing an amorphous-pyrogenic or fumed silica and a micro or short fiber filler material such as calcium silicate are useful in preparing trowelable thermosettable resin compositions. They are particularly suitable for use in epoxy resin compositions.
Claims25
A filler mixture comprising
- (a) from about 1 to about 20 percent by weight of amorphous-pyrogenic silica and
- (b) from about 80 to about 99 percent by weight of a micro or short fiber inorganic filler material.
A filled, curable, thermosettable resin composition containing a thermosettable resin, a curing quantity of a curing system therefor and a sufficient quantity of a filler mixture so as to render the composition non-flowable and trowelable, said filler mixture comprising (a) from about 1 to about 20 percent by weight of amorphous-pyrogenic silica and (b) from about 80 to about 99 percent by weight of a micro or short fiber inorganic filler material.
