The purpose of this study was to evaluate the effect of acidic primers on bonding magnetic steel alloys. Three alloys (XM27, 447J1, and AUM20) were primed with one of the following materials: Acryl Bond, Estenia Opaque Primer, Eye Sight Opaque Primer, M. L. Primer, or Super-Bond liquid. The specimens were bonded with a tri-n-butylborane initiated resin, and bond strength was determined both before and after thermocycling in water. Unprimed specimen was considered as the control. Average bond strength varied from 0 to 45.3 MPa for the XM27 alloy, 0.3 to 43.6 MPa for the 447J1 alloy, and 0.5 to 41.1 MPa for the AUM20 alloy. Of the five primers, Estenia Opaque Primer exhibited better adhesive performance than the other materials regardless of the type of steel alloy. It can be concluded that the use of the Estenia Opaque Primer, which contains an adhesive monomer (10-methacryloyloxydecyl dihydrogen phosphate; MDP), is recommended for bonding the three magnetic steel alloys with TBB-initiated resin.
本研究的目的是评估酸性底漆对粘结磁性钢合金的影响。三种合金（XM27、447J1和AUM20）用以下材料之一进行底漆处理：丙烯酸粘结剂、埃斯特尼亚不透明底漆、视力不透明底漆、M.L.底漆或超级粘结剂液体。将试样用三正丁基硼烷引发的树脂粘结，并在水中进行热循环前后测定粘结强度。未进行底漆处理的试样作为对照。XM27合金的平均粘结强度在0至45.3MPa之间，447J1合金在0.3至43.6MPa之间，AUM20合金在0.5至41.1MPa之间。在这五种底漆中，无论钢合金类型如何，埃斯特尼亚不透明底漆都比其他材料表现出更好的粘结性能。可以得出结论，建议使用含有粘结单体（10-甲基丙烯酰氧基癸基磷酸二氢酯；MDP）的埃斯特尼亚不透明底漆，用TBB引发的树脂粘结这三种磁性钢合金。
