All suppliers have different msds sheets, you really need the msds from the company that you bought it from in case anything ever happens or you have a routine inspection from the D.O.T. Highway Troopers.
It is very easy, just call the place you bought it from and they can fax it to you, if you don't have a fax, go to Staples, Office Depot, Office Max, etc... but you can also just have them mail it to you or just go and get it, it is really just that simple, a lot cheaper to drive 45 miles than pay for the ticket if you don't have it with you in a routine inspection.
Good Luck.
