Abstract

Wooden materials are advantageously modified with the treatment of the product of co-hydrolytic condensation of (A) 100 parts by weight of an organosilicon compound having the formula:

(R1)a(OR2)b SiO(4-a-b)/2(1) wherein R1 is alkyl, R2 is alkyl, 0.75 <= a <= 1.5, 0.2 <= b <= 3 and 0.9 < a+b <= 4, and (B) 0.5-49 parts by weight of an amino-containing alkoxysilane having the formula:

R3R4NR5-SiR6n (OR2)3-n (2) wherein R3 and R4 are H or alkyl or aminoalkyl, R5 is a divalent hydrocarbon group, R6 is alkyl, and n is 0 or 1, or a partial hydrolyzate thereof in the presence of an organic acid or inorganic acid.
