Water-dilutable concentrate for production of coating materials, especially for textile treatment, contains an organosol from hydrolysis of alkoxysilane, plus metal alkoxide, complex former and water-miscible solvent

摘要

A sol-based, water-dilutable concentrate (WDC) for the production of coating materials, containing (A) an organosol obtained by the hydrolysis and condensation of alkoxy-organosilane(s), (B) alkoxide(s) of titanium, zirconium, hafnium or aluminum, (C) complex former(s) to reduce the rate of hydrolysis and (D) a water-compatible or -miscible solvent with a boiling point of at least 150[deg]C. A sol-based, water-dilutable concentrate (WDC) for the production of coating materials, containing a mixture of (A) 0.5-25 wt% of an organosol obtained by the hydrolysis and condensation of alkoxysilane(s) of formula R 4 - xSi(OR~) x (I), (B) 4-55 wt% alkoxide(s) of formula Me(OR~) n (II), (C) 0.1-15 wt% complex former(s) to reduce the rate of hydrolysis of (A) and (B), and (D) 5-95 wt% water-compatible or water-miscible solvent with a boiling point of at least 150[deg]C. R~ : optionally substituted 1-8C hydrocarbyl; R : optionally substituted 1-22C hydrocarbyl; x : 1, 2 or 3; Me : Ti, Zr, Hf or Al; n : the valency of Me . Independent claims are included for (1) transparent coating materials (TCM) with good storage stability containing WDC and water in a wt. ratio of (100:1)-(1:500) (2) textile material with a surface coating obtained by applying and drying TCM .
