Adhesive formula of the hottest polymer
2022-10-19- Detail
Adhesive formula of polymer
Formula 1
polyamide (nylon Zytel 61) 3493
epoxy resin (Dow der331) 1743
dicyandiamide 53
ethanol 5216
MEK yellow dye 3
polyamide powder (nylon Zytel 33, 80 mesh) 71
preparation method
soluble polyamide and water obtained by reacting adipic acid ester, adipic acid sebacate and caprolactam(or ethanol) mixing, Nylon Zytel 61 is available. Dow der331 is a polyglycerol ether of bisphenol A, with a molar mass of 186 ~ 192. Nylon zytel33 is a kind of nylon, which can be prepared by the reaction of hexamethylene diamine and adipic acid
formula 2
group A: diglycerol ether of bisphenol A (epikote828) 100
group B: modified aliphatic amine (epiuyet) 10
polyamide curing agent (versamidl25) 86
group A is resin, and group B is curing agent
preparation method
mix group B evenly first, and then add group B to group A
suitable for sealing cable interface
formula 3
complex of boron trifluoride and ether (containing 48% boron trifluoride) 7.5
triethylamine 5.75
polyethylene glycol (molar mass about 600) 37
preparation method
after the materials are mixed, triethylene makes it clear that the environmental protection treatment requirements of the project require that amine can replace ether to form the complex of boron trifluoride and triethylamine. It is suitable for the bonding of textiles and urethane polymers
formula 4
diphenylmethane diisocyanate 30
silicone rubber 70
the composition of silicone rubber is: hydroxy polydimethylsiloxane (value= "25" unitname= "℃"> when in good test condition, the viscosity at 25 ℃ is 4000 centipoise) 100
silica (treated with trimethylsilane)
