Coating resin crosslinking agent
The polymer compounds that contain epoxy groups in the molecular structure are called epoxy. After cross-linked epoxy resin has good physical and chemical properties, on the surface of the metal and nonmetal material has excellent bonding strength, good dielectric properties, setting small shrinkage, drying products good dimensional stability, high hardness, good flexibility, the alkali stability and most solvents.
Polyurethane is known as polyurethane, which is a general term for a large molecule compound containing a compound called carbamate. It is made up of organic diisocyanate or polyisocyanates with dihydroxy or polyhydroxy compounds. Polyurethane is different from other resins.
In polyester resin in addition to the hydrocarbon containing ester bond, only contained in polyether ether bond, but except ammonia ester bond in the polyurethane resin, can be contained many ester, ether keys, urea formate keys, the unsaturated double bond of cyanuric acid ester bond, grease, and acrylic ester composition, occupy acrylate even more than the number of ammonia ester bond, but still always called polyurethane coating, approximate block copolymer, actually.
Polyurea resin is a polymer that urea reacts with formaldehyde. Also called urea formaldehyde resin. UF abbreviations. When processing and forming, it happens to be crosslinked, and the product is an insoluble thermosetting resin. After crosslinking of urea-formaldehyde resin colors than phenolic resin light, translucent shape, weak acid, weak alkali resistance, good insulation performance, excellent wear resistance, cheap, but in strong acid, strong alkali easy decomposition, poor weather resistance.
Chlorinated polyolefin resin is a fatty hydrocarbon resin that is substituted for the chlorine atom by the main chain. Main varieties are: chlorinated rubber, chlorosulfonated polyethylene, chlorinated polyvinyl chloride, chlorinated polyethylene, chlorinated polypropylene, chlorinated ethylene/vinyl acetate copolymer and vinyl chloride - vinyl isobutyl ether copolymers, etc.
The chlorine, chlorine polymer molecules is introduced form the polarity of the larger C - Cl key, it has excellent weather resistance, ozone resistance, resistance to chemical media (acid, alkali, salt) and certain fatty hydrocarbon solvent resistance and the refined oil, lubricating oil and so on, can be used for the preparation of single-component coating, construction is convenient, is not affected by the construction environment. So it is widely applied to anti-corrosive coatings; Meanwhile, CPR is good adhesion to low-surface plastic, and it also applies to some decorative coatings.
Cellulose nitrate abbreviation NC. Known as nitrocellulose, the product of the reaction of cellulose and nitric acid esterification. Cellulose nitrate, which is made from cotton fibre, is called nitrocotton. Cellulose nitrate is a white fibrous polymer that is resistant to water, dilute acid, weak base and various oils. The degree of polymerization is different, but it is all thermoplastic. It is easy to change color in the sun and it burns easily. Be aware of safety in manufacturing, packaging, shipping and sales and use.

Silicone is highly crosslinked network structure of organic siloxane, usually with methyl trichlorosilane, dimethyl dichlorosilane, phenyl trichlorosilane, diphenyl dichlorosilane or various mixture of methyl phenyl dichlorosilane, in the presence of organic solvents such as toluene, hydrolytic decomposition under low temperature, acid hydrolysate.
The initial products of hydrolysis are circular, linear and cross-linked polymers, and usually contain quite a bit of hydroxyl. The hydrolysate are washed to remove acid, neutral at the beginning of the condensation polymer thermal oxidation in air or in the presence of catalyst further polycondensation, eventually forming the highly crosslinked three-dimensional network structure.
Silicone is a thermosetting plastic, one of its most outstanding properties is excellent thermal oxidation stability. Another outstanding performance of silicone resin is excellent insulation performance. In addition, the silicone also has excellent resistant to moisture, waterproof, antirust and hardy, ozone resistance and weather resistance, for the vast majority of aqueous chemical reagents such as dilute mineral acid corrosion resistant performance is good, but the poor solvent resistance.
Fluorocarbon resin with solid C - F keys for the skeleton, compared with other resin, its heat resistance, chemical resistance, cold resistance, low temperature flexibility, weather resistance and other performance is good, and due to its good crystallization, therefore has not adhesion, not wet.
Because of fluorocarbon resin are high melting point (180 ~ 380 ℃), does not dissolve in the solvent of solid resin, made into water or solvent dispersible coating, spraying, electrostatic spraying, episodic curtain coating, roller coating, or made into powder coating, coating by the electrostatic spraying or fluidized bed dip-coating method.
