The Basic Structure and Characteristics of Organic Silicon Anticorrosive Coating

Organosilicon compounds refer to compounds that contain Si-O bonds and at least one organic group is directly connected to the silicon atom. It is customary to connect the organic group to the silicon atom through oxygen, sulfur, nitrogen, etc. Also used as an organosilicon compound. Among them, polysiloxane composed of silicon-oxygen bond (-Si-0-Si-) is the most numerous, most researched and most widely used type of organosilicon compounds, accounting for more than 90% of the total amount.


The basic structural unit of organosilicon anticorrosive coating is composed of silicon-oxygen chain links, and the side chain is connected to various other organic groups through silicon atoms. Therefore, the structure of the silicone anticorrosive coating contains both "organic groups" and "inorganic structures". This special composition and molecular structure make it integrate the characteristics of organic substances and the functions of inorganic substances.


The features of silicone anticorrosive coatings are as follows:


Chemical properties: acid and alkali resistance, salt spray resistance, solvent resistance, high and low temperature resistance, UV resistance.


Biological characteristics: With antibacterial function, it can effectively simulate the growth of plankton such as algae and fungi.


Application characteristics of silicone anticorrosive coating:


a) Good stain resistance, can resist various water-based and oily stains, including algae adhesion, and is easy to clean.


b) Good airtightness and seamless construction as a whole, which can greatly reduce water penetration loss and facilitate cleaning.


c) Good adhesion, strong adhesion to metal, cement, ceramic tiles, glass, wood, epoxy and acrylic based coatings, internal and external wall putty.


d) The material has high strength, scratch resistance, washing resistance, and heavy pressure resistance, and the surface is ceramicized.
