Several common coating crosslinking agents
Crosslinking agent is also known as curing agent, curing agent, curing agent, it can make linear or mild branched macromolecules into a 3 d mesh structure, improving strength, heat resistance, abrasion resistance, solvent resistance, such as performance, can be used for foam or not foam products.
Common crosslinking agents are organic peroxide, with the following:
Diisopropyl benzene (DCP)
Is most commonly used, 1.08 g/cm3 density, melting point 42 ℃ and decomposition temperature of 120 ~ 125 ℃, the refractive index of 1.54, 117 ℃ has a half-life of 10 hours, often associated with zinc oxide and use, improve the strength and aging resistance.
Benzoyl peroxide (BPO)
White powder, melting point 103 ~ 106 ℃, unstable, insoluble in water, slightly soluble in organic solvents.
Ditert-butyl peroxide (DTBP)
Light yellow transparent liquid, density of 0.8 g/cm3, boiling point 110 ℃, flash point 183 ℃, the refractive index of 1.4, 126 ℃ has a half-life of 10 hours.
Hydrogen peroxide diisopropyl benzene
Light yellow liquid, heat or contact with acid base is easily decomposed.
Chinese name: Diethyl toluene diamine(DETDA)
Chinese alias: aryl, aryl diethyl - aryl - methyl-p-phenylenediamine
English name: Benzenediamine, ar, ar-diethyl-ar-methyl-English aliases:Diethyltoluenediamine; ar, ar-Diethyl-ar-methylbenzenediamine;Diethylmethylbenzenediamine;
CAS No. :68479-98-1
EINECS No. :270 -877-4
Molecular formula: C11H18N2
Molecular Weight: 178.28
Boiling point: 310 ℃
Refractive index: 1.581
Flash Point: > 140 ℃
Inchi: InChI = 1/C11H18N2/c1-4-8-6-7 (3) 10 (12) 11 (13) 9 (8) 5-2/h6H ,4-5,12-13H2 ,1-3H3 density : 1.022

And diethylene triamine (DTA), also called diethylenetriamine, colorless liquid, the boiling point 207 ℃, 0.954 g/cm3 density, refractive index of 1.5, flash point 94 ℃, commonly used in epoxy resin, the general content 5% ~ 10%.
We have 2, 5-dimethyl-2, and then tertiary butyl peroxide
There are two kinds of products for short, a light yellow liquid of 90% purity and 0.85 grams per cubic centimeter. Another 50% purity of white powder, decomposition temperature of 179 ℃ (half-life 1 minute), and 118 ℃ (has a half-life of 10 hours). Double 25 is a kind of high temperature crosslinking agent, which is used in ethylene acetate copolymer, polyethylene, chlorinated polyethylene, etc., which can improve the strength and hardness of the products. 2 - ethyl - 4 methyl imidazole, 2 - phenyl imidazole, 2 - isopropyl imidazole, four six hydrogen gas phthalic anhydride, phthalic anhydride, sanya ethyl amine, dimethylamino propylamine, diethylamine propylamine, etc are also crosslinking agent, the most used for thermosetting plastics, used as curing agent.
The crosslinking agent is mainly used in acrylic emulsion, polyurethane emulsion, carboxylic butyl benzene emulsion, etc., to improve the adhesion strength and surface adhesion of emulsion.
The crosslinking agent is applied in the following areas: water-based acrylic pressure sensitive adhesive, water-based acrylic adhesive, water-based acrylic coating, water-based acrylic leather coating agent, etc.
