A moisture barrier coating includes the reaction product of (A) at least one polyol and (B) at least one polyisocyanate. The moisture barrier coating further includes at least one amorphous thermoplastic material that forms a homogeneous mixture with the polyol, and is nonreactive with the polyol and with the polyisocyanate. A controlled release fertilizer, a method for the production of a controlled release fertilizer, and a moisture barrier coating composition are also disclosed.

Polyurethane moisture barrier coatings containing thermoplastic resins

A moisture barrier coating includes the reaction product of (A) at least one polyglycidyl ether resin, and (B) at least one epoxy curing agent comprising amines. The moisture barrier coating further includes at least one amorphous thermoplastic material that is nonreactive with A and with B, and that forms a homogeneous mixture with at least one of A or B. A controlled release fertilizer, a method for the production of a controlled release fertilizer, and a moisture barrier coating system are also disclosed.
