La pasta termica tiene fecha de caducidad o de vencimiento?

hola amigo, mientras tengas la pasta a temperatura ambiente y en su caja o su defecto en en lugar oscuro te puede durar muchos años, en la caja de igual forma no generan fecha de vencimiento, y la verdad te la recomiendo 100% la he utilizado en todos mis portátiles y en dos consolas ps3 y si nota su mejora ante recalentamientos ni los video juegos ni los portátiles se me apagan

Will this product work on a vertical surface? Or, once it heats up will it drip?

Yes, this will work just fine in a vertical surface. Most CPU's in PC's are mounted vertical and that's what this is designed for.
