1. A coating for granular products, the coating comprising:
a functionalized polymer, where the functionalized polymer is a solution and where the functionalized polymer comprises maleic anhydride/acid and diisobutylene; and
a carrier, where the carrier is paraffin oil, raffene oil, bright stock, rerefined base oil, base oil, petroleum-based oil, or a combination thereof;
where the coating is pumpable at ambient temperature.
 
6. A method of reducing moisture adsorption in a granular or compacted product, the method comprising:
combining a functionalized polymer with a carrier to produce a coating, where the functionalized polymer is a solution; the functionalized polymer comprises maleic anhydride/acid and diisobutylene; and the carrier is paraffin oil, raffene oil, bright stock, rerefined base oil, base oil, petroleum-based oil, or a combination thereof and where the coating is pumpable at ambient temperature; and
coating a granular or compacted product with the coating, where the coating is not heated prior to coating the granular or compacted product with the coating.
