Separate textures for identical objects?

Hello, i am trying to make a title screen in unity. I have two models, of which one is the outline. when i try to apply a certain material to one of the models, the other one takes this too. i tried importing it a second time (so it says i have asset 1 and asset 2 for example), but it still uses one texture for both. how can i turn this function off?

Make another material for your second object
