This invention provides a method for forming a multilayer coating film, comprising applying a base paint (X) having a solids content ratio of 30 to 62 mass % to a substrate to form a base coating film having a cured film thickness of 6 to 45 μm; applying an effect pigment dispersion (Y) having a solids content ratio of 0.1 to 10 mass % to the base coating film to form an effect coating film having a cured film thickness of 0.1 to 5.0 μm; applying a two-component clear paint (Z) containing a hydroxy-containing resin and a polyisocyanate compound to the effect coating film to form a clear coating film; and heating the base coating film, the effect coating film, and the clear coating film to simultaneously cure these coating films; wherein the base paint (X) contains a polyurethane resin (A), an alcohol (B) containing 6 to 12 carbon atoms, and an organic solvent (C) having an HLB of 7 to 9, and the effect pigment dispersion (Y) contains water, a flake-effect pigment (P), a resin emulsion (Q), and cellulose nanofibers (R).

A relatively low cost, two component solvent-based urethane coating, intended to protect steel shipping containers made from modified drying oils.

A sheet molding compound according to a first aspect of the present invention comprises: a thickened product of a resin composition comprising a vinyl ester resin, a thickener, a polymerization initiator, a polymerization inhibitor and isobornyl methacrylate; and a reinforcing fiber.

Described herein is a process for preparing urethane (meth)acrylates. In a first step, a hydroxyalkyl (meth)acrylate is reacted with a lactone (B) in the presence of at least one zinc compound and/or bismuth compound (C) to produce a resulting zinc-containing product and/or a bismuth-containing product, and, in a further step, the zinc-containing product and/or the bismuth-containing product is reacted with at least one cycloaliphatic or asymmetric aliphatic diisocyanate (D).
