Abstract
Described are preferred methods for promoting interfacial bonding between surfaces containing oxide, hydrous oxide or hydroxyl groups. The methods involve attaching silane coupling agents to the opposed surfaces and, in turn, bonding the opposed silane coupling agents to each other to thereby promote interfacial bonding between the surfaces. Also described are preferred compositions for promoting such interfacial bonding.
Claims16
A method of interfacially bonding oxide-, hydroxide-, or hydrous-oxide-containing surfaces, comprising:
- reacting between said a bonding agent consisting essentially of surfaces an alkylating silane coupling agent and a pyridine-containing polymer, said alkylate silane coupling agent having an alkylation function effective to alkylate pyridine nitrogens, said alkylating function being selected from the group consisting of a halogen and a sulfonic acid ester group;
- so as to cause said surfaces to be interfacially bonded.
A composition for interfacially bonding surfaces containing, oxide, hydrous oxide or hydroxide groups, comprising:
- an alkylating silane coupling agent and a pyridine-containing polymer or precursor monomer therefor, said alkylating silane coupling agent having the formula:
- F(.sub.4-n)SiR.sub.n
- wherein:
- n is 1 to 3;
- F is a readily hydrolyzable group selected from the group consisting of halogens and oxy groups of the formula --O--R' wherein R' is an aliphatic group containing 1 to about 8 carbon atoms;
- and
- R is an aliphatic or mixed aliphatic-aromatic group containing an alkylating function effective to alkylate pyridine nitrogens, said alkylating function being selected from the group consisting of a halogen bonded to an aliphatic carbon and a sulfonic acid ester group;
- said alkylating saline coupling agent and said pyridine-containing polymer or precursor monomer therefor being included in effective amounts to interfacially bond said surfaces.
