Compositions for polymer bonding

A method of bonding two substrates together, the method comprising:

• (i) substantially hydrolysing a compound comprising:
• a) at least one alkoxy silane moiety;
• and
• b) at least one moiety selected from an aromatic nitroso or an aromatic nitroso precursor and combinations thereof;
• (ii) applying the substantially hydrolysed compound of step (i) to at least one substrate;
• and
• (iii) mating the first and second substrates so as to form a bond therebetween.

A method of bonding two substrates together, the method comprising:

• A. providing a composition comprising:
• (i) a compound comprising:
• a) at least one alkoxy silane moiety;
• and
• b) at least one moiety selected from an aromatic nitroso or an aromatic nitroso precursor and combinations thereof;
• and
• (ii) a carrier for the compound, the carrier comprising at least 0.1% water;
• B. heating the composition;
• and
• C. applying the composition to a bonding surface of at least one of the substrates and bringing the bonding surfaces of the substrates together.

A process for using an adhesive composition comprising the steps of:

• A. Providing two substrates having matable surfaces
• B. Providing a composition, said composition comprising:
• (i) a compound comprising:
• a) at least one alkoxy silane moiety;
• and
• b) at least one moiety selected from an aromatic nitroso or an aromatic nitroso precursor and combinations thereof;
• and
• (ii) a carrier for the compound, the carrier comprising at least 0.1% water;
• C. Providing said composition on at least one matable surface of at least one substrate or between the matable surfaces of the two substrates;
• and
• D. Exposing the composition to temperature conditions in the range of from 30 to 100° C.
