TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The coupling agent can also be silane coupling agent. The dye is transparent blue dye.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: Diluting agent is selected from benzyl glycidol ether, tert. butyl phenol glycidol ether, butyl glycidol ether, 2-ethylhexyl glycidol ether, n-octanol glycidol ether, C12-14 alcohol glycidol ether, o-cresol glycidol ether, aryl glycidol ether, glycol glycidol ether, neopentyl glycol glycidol ether, diethylene glycol glycidol ether, 4-cyclohexane dimethanol glycidol ether, or trimethylolpropane glycidol ether, or their mixture. Defoamer is selected from tributyl phosphate, isooctyl alcohol, simethicone, polyethylene glycol glycerin ether or dimethyl siloxane or their mixture. Coupling agent is selected from tribasic ester coupling agent, boric acid ester coupling agent or ester aluminate coupling agent or their mixture. Aliphatic polyamine is selected from diethylenetriamine, triethylenetetramine, tetraethylenepentamine, polyethylene polyamine, solidified agent 593, 3-dimethyl amino propyl amine, 3-diethylamniopropylamine, 1, 6-ethylene diamine, amine terminated polyether or polyether amine or their mixture.

The accelerating agent is selected from 2, 4, 6-tri-(dimethylaminomethyl) phenol, m-cresol, resorcin, phenol, or N-ethyl-N-phenyl dithiocarbamic acid zinc or their mixture.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The organic silicon modified epoxy resin is obtained by reacting epoxy resin with amino silicone oil (I).R=1-5C straight or branched-chain alkyl.Epoxy resin mixture is a mixture of bisphenol A epoxy resin and bisphenol F epoxy resin. Bisphenol A epoxy resin is selected from bisphenol A epoxy resin whose epoxy value is 0.51 mole per 100 gram, a bisphenol A epoxy resin whose epoxy value is 0.54 mole per 100 gram and a bisphenol A epoxy resin whose epoxy value is 0.56 mole per 100 gram or a mixture of more than one of them. Epoxy value of the bisphenol F epoxy resin ranges from 0.55-0.59 mole per 100 gram.
