A Brief Introduction and Characteristics of Acrylic Acid
1. What is acrylic acid?
Acrylic acid is an important organic synthesis raw material and synthetic resin monomer, and it is a vinyl monomer with a very fast polymerization rate. Acrylic acid is also known as: acrylic (ester) copolymer, acrylic acid CAS No.: 25035–69–2.
2. Introduction of acrylic acid
Acrylic acid is the simplest unsaturated carboxylic acid, consisting of a vinyl group and a carboxyl group. Pure acrylic acid is a colorless, clear liquid with a characteristic pungent odor. It is miscible with water, alcohol, ether and chloroform, and is prepared from propylene obtained from an oil refinery. Most of them are used to make acrylates such as methyl acylate, ethyl acrylate, butyl acrylate and hydroxyethyl acrylate.
3. The properties of acrylic acid
Waterborne acrylic anti-corrosion coatings are usually used in medium and light anti-corrosion fields, usually consisting of a combination of three coats of primer, middle coat and top coat to form a coating system and play a role. Primer is the basis of the entire coating to prevent the penetration of water, ions and oxygen. It has good adhesion and corrosion resistance. It can be used with water-based epoxy and acrylic primers, and it can also be used with solvent-based coatings to form a composite system.
Acrylic intermediate coating is mainly used to improve the adhesion to the topcoat and primer, to make the bonding between the two coating films closer, increase the thickness of the coating, and improve the shielding ability of the entire coating system; the topcoat has beautiful decoration and anti-permeation effect, usually a pigment-free varnish to improve the weather resistance of the entire coating.
Douwin Chemical Company has four wholly-owned subsidiaries: Shanghai Douwin Chemical Co., Ltd, Suzhou Douwin Chemical Co., Ltd, Ningbo Douwin Chemical Co., Ltd, and Dulwich International Co., Ltd, and also has two joint venture companies: Guangzhou Dewangtai Trading Co., Ltd and Suzhou Yanxi Chemical Trading Co., Ltd. These six companies share resources and information and are complementary in upstream suppliers and downstream market information.
