Problems solved by technology

These solvent-free, liquid-based systems can require expensive non-standardized equipment to apply the coating
However, solvent-free liquid-based systems have disadvantages like other liquid-based systems, including pre-mixing, monitoring and maintaining viscosity, and the potential for running or sagging during and after application of the coating

Embodiment 1

[0053] Embodiment 1 (adduct containing oxazolidinone ring)

[0054] 390 grams (g) D.E.R. TM 736 was added to the flask and the contents of the flask were heated to 130°C. 2 g of DBU was added to the flask over a period of approximately 60 seconds and the contents of the flask were maintained at 145°C. 210 g of MDI was added to the flask over 60 min and the temperature of the contents of the flask was maintained at a temperature of 160°C to 170°C. The contents of the flask were kept at a temperature of 165 °C for 15 min. A sample was obtained and the EEW was determined to be about 1450. 280g D.E.R.TM 330 was added to the flask and the contents of the flask were maintained at a temperature of 140°C to 150°C. 120 g of MDI was added to the flask over 60 min and the temperature of the contents of the flask was maintained at a temperature of 170°C to 175°C. The contents of the flask were kept at a temperature of 165 °C for 15 min to generate Example 1. Epoxy equivalent weig...

Abstract

Embodiments include oxazolidone ring containing adducts obtainable by combining an aliphatic epoxy compound, an aromatic epoxy compound, and a diisocyanate. Embodiments further include a curable powder coating composition including a resin component and a hardener component, where the resin component includes the oxazolidone ring containing adduct.

Description

technical field [0001] The present disclosure relates to adducts, particularly adducts containing oxazolidinone rings. Background technique [0002] Epoxy systems consist of two components that can chemically react with each other to form a cured epoxy resin, which is a hard, inert material. The first component is the epoxy resin and the second component is the curing agent, sometimes called the hardener. Epoxy resins are substances or mixtures that contain epoxy groups. Hardeners include compounds that react with the epoxy groups of the epoxy resin. [0003] Epoxy resins can be crosslinked, also known as cured, through a chemical reaction of epoxy groups with hardener compounds. This curing converts a relatively low molecular weight epoxy resin into a relatively high molecular weight material through the chemical addition of hardener compounds. [0004] Epoxy systems are used in a variety of applications, including coatings. Coatings are used to treat surfaces to resis...
