Embodiment Construction

[0007] The composition of the in-mold and exterior coatings of the present invention is based on a thermosetting copolymeric composition comprising urethane acrylate oligomers, sulfonic acid functional acrylate monomers and acrylic monomers, the remainder being copolymerizable diacrylates and and / or copolymerizable monoethylenically unsaturated monomers, wherein mixtures of diacrylates and monomers are preferred.

[0008] The first thing to talk about is urethane-acrylate oligomers. Acrylate-functional reactive oligomers are low-molecular-weight urethane intermediates terminated with acrylate or methacrylate. A preferred urethane intermediate comprises the reaction product of an excess of isocyanate, preferably diisocyanate, with a small amount of polyol, preferably diol, resulting in an isocyanate-terminated low molecular weight linear urethane intermediate. The urethane intermediate is further reacted with a hydroxyalkyl acrylate to produce an acrylate functional oligomer te...

Abstract

An in-mold coating composition particularly useful for in-mold coating of molded nylon based substrates comprises a coreactive addition polymerizable composition of urethane-acrylate oligomer having at least two acrylate and / or methacrylate terminal groups, at least 0.2% of a sulfonic acid functional acrylate or methacrylate, at least 0.2% of acrylic and / or methacrylic acid, with the balance being coreactive polymerizable diacrylate(s) and / or ethylenically unsaturated monomer(s).

Description

technical field [0001] The present invention relates to an in-mold coating for thermoplastic substrates, and in particular to reactive urethane-acrylates that can be copolymerized with other ethylenically unsaturated components to provide a coating for thermoplastic nylon and modified Thermoset molded interior and exterior surface coating on nylon substrate. Background technique [0002] Thermoplastic substrates are generally based on the conversion of thermoplastic resins, powders, granules, pellets and similar forms of thermoplastic resin materials under heat and pressure to form suitable molded articles. Injection molding methods for molding thermoplastic resin materials generally include heating the molding compound to form a viscous, flowable melt, injecting the hot melt under high pressure into a relatively cool, closed mold cavity, cooling the The molten body, thereby forming a mold base in a solid shape consistent with the internal structure of the mold cavity, and ...
