A number of thermosetting acrylic resins for use as surface coatings have appeared during recent years. These are generally complex copolymers and terpolymers such as a styrene-ethyl acrylate-alkoxy methyl acrylamide... 

Determination of MCT. The coating systan used consists of a thermosetting acrylic latex, Hycar 2600X256 (EFGoodrich Chenical Division) containing 15 wt.% of a partially methylated melamine formaldehyde, Cymel 373 (American Cyanamid Corporation). Adjustment of the pH level of the coating was achieved by the addition of p—toluene sulfonic acid. 

Binders for thermosetting powder coatings are often called a hardener. The hardeners are a mixture of a primary resin and a cross-linker. The major types of binders can be limited to polyester, epoxy, hybrid epoxypolyester, acrylic, and UV cure types. Polyester binders are used for good exterior durability, retention of gloss, and resistance to chalking. 

The thermoset acrylics (20) of major importance in the coating industry, in recent years, have been developed primarily by Canadian Industry Ltd. and by Pittsburgh Plate Glass Co. in this country (4). Raw materials are acrylamide, acrylic acid, acrylates, and styrene. Cross-linking agents are amino and epoxy resins. The materials are also self-cross-linking. They are usually sold as solutions in paint solvents. 

CAS 999-61-1. CH2CHCOOCH2CH2OCH3. A functional monomer used in manufacture of thermosetting acrylic resins for surface coatings. 

A major revolution in appliance coatings came about with the discovery by Strain (4) of the thermosetting acrylic. This was made practical by Christenson (, Sekmakas (6, 7), and others (8). 

Topcoats. For some applications such as chest freezers or vacuum cleaners, alkyds are still employed. These evolved from oil-modified types to the oil-free polyesters that have good stain resistance, high gloss, and excellent flexibility. But until recently, the thermosetting acrylic was the hallmark of appliance coatings. Acrylics exhibit excellent hardness, adhesion, chemical...
