Adhesive useful for installing vehicle windows
Disclosed are compositions comprising: a) one or more isocyanate functional components; b) one or more alkoxyalkyl benzoates; and c) one or more catalysts for the reaction of isocyanate moieties with hydroxyl groups. Disclosed is a method of bonding two or more substrates together comprising contacting two or more substrates together with a composition disclosed herein disposed along at least a portion of the area wherein the substrates are in contact. At least one of the substrates may be window glass. One of the other substrates may be a building or a vehicle.
1. A composition comprising: a) one or more isocyanate functional components in an amount of about 20 to about 60 percent by weight; b) 1-methoxy-2-propyl benzoate in an amount of about 5 to about 40 percent by weight; c) one or more catalysts for the reaction of isocyanate moieties with hydroxyl groups in an amount of about 0.005 to about 2 percent by weight; and d) one or more carbon blacks in an amount of about 10 to about 35 parts by weight; wherein percentages are based on the weight of the composition.
2. A composition according to claim 1 wherein the composition further comprises one or more isocyanate functional polyester based prepolymers which are solid at 23° C.
3. A composition according to claim 1 wherein the composition further comprises one or more polyisocyanates having a nominal functionality of about 3 or greater.
4. A method of bonding two or more substrates together which comprises contacting the two or more substrates together with a composition according to claim 1 disposed along at least a portion of the area wherein the substrates are in contact.
5. The method of claim 4 wherein the at least one of the substrates is window glass.
6. A method according to claim 4 wherein at least one of the other substrates is a building or a vehicle.
7. The method according to claim 4 wherein the substrate is a vehicle.
8. A method of replacing a window of a vehicle comprising: i) removing the window from the vehicle; ii) applying a composition according to claim 1 to a replacement window or to the flange of the vehicle adapted to hold the window into the vehicle; iii) contacting the flange of the vehicle and the replacement window with the composition disposed between the replacement window and the flange of the vehicle; and iv) allowing the adhesive to cure.
9. The method of claim 8 wherein the vehicle can be safely driven after 60 minutes from installation of the window into the vehicle.
