* using catia v 5
Go to edit, scene. You should then see a window with the name of your project - right click the name, and click on "unlink all materials". You will now be able to apply materials to individual surfaces.
Another easy way is to group objects together into different layers (depending on what program you're using - I use Rhino so it's layers) - then when you import into keyshot, it preserves the layers, so you can apply a different material to each layer. Can be much quicker than doing it for each individual surface.
The first way is very time-consuming, only suggested it because it's the most simple. Hopefully someone who knows Catia can tell you how to group things together in the project before importing - as vinothkumar.m said, it's a good habit to get into.
