Tetrabutyl orthosilicate

Abstract—The effects of metal alkoxide type and relative humidity on the durability of alkoxide-primed, adhesively bonded steel wedge crack specimens have been determined. Aluminum tri-sec-butoxide, aluminum tri-tert-butoxide, tetrabutyl orthosilicate, and titanium(IV) butoxide were used as alkoxide primers. Grit-blasted, acetone-rinsed mild steel adherends were the substrates bonded with epoxy and polyethersulfone. The two aluminum alkoxides significantly enhanced the durability of the adhesively bonded steel, while the titanium alkoxide showed no improvement in durability over a nonprimed control. The silicon alkoxide-primed samples gave an intermediate response. The failure plane in the adhesively bonded samples varied with the relative humidity during the priming process. [Pg.569]

The two aluminum alkoxide primers on mild steel showed improved adhesion and better resistance to crack propagation with both the thermoplastic polyether-sulfone (PES) and the FM 300U thermoset epoxy adhesive. The titanium alkoxide exhibited the poorest resistance to crack growth, while tetrabutyl orthosilicate showed intermediate behavior between the two aluminum alkoxides and the titanium alkoxide. [Pg.578]

In our studies we synthesized surfactant salts of phosphomolybdic acid (PMA) and reacted them with tetraethyl orthosilicate (tetrabutyl titanate) in a salt-gel reaction in order to obtain a three-dimensional tunnel structure. It is based on the hydrothermal reaction using cetyltrimethylammonium bromide as a structuredirecting agent. Phosphomolybdic acid is unstable when the temperature is over 723 K. Calcination to decompose the template will make the inorganic portion of the structure to collapse invariably and to form dense M0O3.X phases. Therefore, we... [Pg.185]
