Fatty amine coating crosslinking agent
Crosslinking agent is a material that promotes or regulates the crosslinking reaction and makes the material solidify. For example, crosslinking agent is one of the raw materials necessary for the crosslinking of epoxy resins, otherwise the epoxy resin will not be cross-linked. Appropriate crosslinking agents should be used to meet the requirements of various applications.
A lot of fatty amine crosslinking agents are introduced.
Products of different ranges have different performance; High reaction activity, quick crosslinking at room temperature or low temperature; Relatively insensitive to humidity. Having certain color stability; Good chemical resistance, especially solvent resistance; When used for heat crosslinking, it has good high temperature performance. Good chemical resistance and good electrical and mechanical properties.
Fatty amine crosslinking agent: ethylene triamine (DETA)
Ammonia ethyl piperazine (AEP)
Low temperature crosslinking under wet conditions; Good film performance (e.g. surface gloss); Can prevent the spray and water spots of the amine; Good color stability; Good adhesion performance and chemical corrosion resistance; The time of crosslinking and storage time can be wide. When used for heat crosslinking, it has good high temperature performance. Good chemical resistance and good electrical and mechanical properties.
1, 2, diaminocyclohexane (DACH)
Isovosterone diamine (IPDA)
Methylene double cyclohexane amine (4, 4 '- PACM)
ethylenediamine
Performance: toxic, irritant stink, high volatile, low viscosity, rapid crosslinking at room temperature. For adhesion, pouring, coating. This kind of amine increases with the molecular weight, the viscosity increases, the volatilization decreases, the toxicity decreases, the performance improves. But they have big heat and short duration. In general, the larger the molecular weight, the smaller the influence. Chronic exposure to fatty polyamine can cause dermatitis, which is highly toxic and requires great attention in operation.
Chinese name: Diethyl toluene diamine(DETDA)
Physical and chemical properties: light yellow transparent liquid, slightly soluble in water, soluble in alcohols, ethers, ketones and other polar organic solvents, and polyether, polyester polyol compatibility.
Density 1.022
Viscosity (20 ℃) ??mPa·ss290±10
