While installing a new windshield gasket, I managed to tear it at one corner. Can this material be repaired? What kind of adhesive will bond to this stuff?

I would use windshield urethane.
Permatex Ultra Black Silicone
I have used this many times to successfully glue rubber gaskets together with a solid bond. Different rubbers may behave differently but I think it is worth a try
I would apply enough to have it ooze out of the joint and pull the two gasket edges tight using tape, razor blade or X-Acto to trim silicone off once everything dries

Thanks - I'll give it a try - let you know how it works out. Rodney
For a stronger joint, carefully trim the edges of the gasket break so they are perfectly vertical, then use Superglue. This is what NASA uses to make 15 ft OD O-rings for joining booster rocket segments. Even Viton flurocarbon rubber will slightly oxidize in open air, which makes for a weaker glue bond; thats why you need to trim to expose fresh rubber. McMaster-Carr in Los Angeles sells kits to make your own o-rings with this technique. Use just plain Superglue, no extra stuff needed.
Look into locktite 406.
