Abstract
An active chemistry capable of being combined with a carrier to produce a coating for fertilizer or other granular or compacted products, where the coating is capable of being applied at ambient temperature and is capable of reducing moisture adsorption and caking of the granular product. The active chemistry may be a functionalized polymer such as maleic anhydride/acid (from maleic anhydride), itaconic acid, diisobutylene, methacrylic acid, alkyl acrylates (i.e. butyl acrylate), hydroxyl ethyl methacrylate, 2-acrylamido-2-methyl propane sulfonic acid, 3-allyloxy-1,2-propanediol acrylic acid, acrylamide, or a combination thereof.
Claims11
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.
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.
