Abstract
Dispersions of glass fibers are produced by agitating a mixture comprising water, glass fibers and a water solution of a linear polysiloxane containing at least 6 silicon atoms, each of said silicon atoms having 2 non-hydrolyzable oleophilic groups attached thereto.
Claims5
In the process of dispersing glass fibers in an aqueous solution, the improvement comprising:
- vigorously agitating a mixture comprising water, glass fibers and an effective amount of a water solution of a linear polysiloxane containing at least 6 silicon atoms, each of said silicon atoms having 2 non-hydrolyzable oleophilic groups attached thereto, to uniformly disperse said glass fibers in said water.
An aqueous dispersion consisting essentially of:
- a. water;
- b. glass fibers;
- c. cellulose fibers;
- and,
- d. an effective amount of a linear polysiloxane, containing at least 6 silicon atoms and having 2 non-hydrolyzable oleophilic groups affixed to each of said silicon atoms, to hold said fibers dispersed throughout the water.
