Here is a website for a product called Seamfil made specifically for plastic laminate... many colors available.Lots of good info. on this site. Just a suggestion, if you have a local counter top shop or cabinet shop stop by and get a quote on repairs or they may have Semfil available for sale.Check the link below.

I would NOT recommend using SeamFil on this problem.
First it is an extremely rigid material once cured, I suspect the edge banding is a bit flexible and the patch will just open up. The rule of thumb with tile is grout the field, the flat, and caulk any change of plane. You need a flexible solution, good old caulk.
If a good color match cannot be found we used to color our own with a little food coloring. Mix up, trowel in and smooth out with a damp rag.
Next, Seamfil is not made to use on verticle surfaces. It can be messy and run if used for this application. Seamfil is really meant for fine, 1/16" or so, gaps in seam fit ups and minor gouges.
