Abstract
Disclosed herein are methods and compositions for preparing a surface comprising thermoplastic or thermoset material to receive a polysulfide or polythioether sealant or coating, the method comprising applying to the surface an activating composition consisting of a tetraalkoxide of a Group 4 metal, a complex of an alkoxide of a Group 4 metal, or a combination thereof.
Claims26
A method for preparing a surface comprising a thermoset material to receive a polysulfide or polythioether sealant, the method comprising applying to the surface an activating composition consisting of a tetraalkoxide of a Group 4 metal, a complex of an alkoxide of a Group 4 metal, or a combination thereof.
A method for coating a surface comprising a thermoset material with a polysulfide or polythioether sealant, the method comprising
- applying to the surface an activating composition consisting of a tetraalkoxide of a Group 4 metal, a complex of an alkoxide of a Group 4 metal, or a combination thereof, and
- applying a polysulfide or polythioether sealant to the surface carrying the activating composition.
A method for adhering a polysulfide or polythioether sealant to a surface comprising a thermoset material, the method comprising applying to the surface an activating composition consisting of a tetraalkoxide of a Group 4 metal, a complex of an alkoxide of a Group 4 metal, or a combination thereof.
