Abstract
A contact adhering method comprising the steps of: (1) applying a layer of a moisture curable adhesive to at least one of two adherends; (2) maintaning the two adherends in non-contact with each other for a period of time until the surface of the layer of moisture curable adhesive develops tack as a result of exposure to atmospheric moisture; and (3) bringing the two adherends into contact with each other in a tack range.
Claims9
A contact adhering method comprising the steps of:
- (a) applying a layer of a solvent-free moisture curable adhesive comprising:
- polyoxyalkylene including one or more reactive silicon groups in a molecule,
- to at least one of two adherends;
- (b) maintaining the two adherends in non-contact with each other for a period of time beginning upon the application of the layer of moisture curable adhesive, and extending until the surface of the layer of moisture curable adhesive begins curing and develops tack as a result of exposure to atmospheric moisture;
- (c) bringing the two adherends into contact with each other while the surface of the layer of moisture curable adhesive is tacky;
- and
- (d) permitting the moisture curable adhesive to be cured in the absence of heat treatment, thereby adhering said adherends.

A contact adhering method comprising the steps of:
- (a) applying a layer of a solvent-free moisture curable adhesive to at least one of two adherends, said adhesive comprising polyoxyalkylene including one or more reactive silicon groups in a molecule;
- (b) maintaining the two adherends in non-contact with each other for a period of time beginning upon the application of the layer of moisture curable adhesive, and extending for a period of time of 24-32 minutes until the surface of the layer of moisture curable adhesive begins curing and develops tack as a result of exposure to atmospheric moisture;
- (c) bringing the two adherends into contact with each other 5-50 minutes after completion of step (b), while the surface of the layer of moisture curable adhesive is tacky;
- and
- (d) permitting the moisture curable adhesive to be cured in the absence of heat treatment, thereby adhering said adherends.
