溴化阻燃型環氧樹脂
溴化阻燃型環氧樹脂是在雙酚A型環氧樹脂的分子結構中引入了溴元素，使其固化組成物具有優良的阻燃性與耐霉菌性。環氧樹脂中溴含量達到16%以上，就具有良好的自熄性能，溴含量越高，阻燃性能就越好。因此溴化環氧樹脂被廣泛應用于電子、電器、航空、船舶、土建等領域的阻燃灌封材料、阻燃層壓板合粘劑等方面。
CYD-450A80是FR-4覆銅板專用溴化阻燃樹脂，該樹脂具有高純度、高反應活性、穩定性好、專用性強等特點。固化物具有良好的阻燃性、耐熱性及良好的電器性能、耐化學品性、優良的粘結性等特性，特別適合與雙******及咪唑類固化及配套使用，制造FR-4覆銅板。
Brominated epoxy resin
Brominated epoxy resin is of wonderfull flame retardancy and fungus resistance by introduceing br into the molecular structure of bpa epoxy resin. This kind of eposy resin coutaining br content over 16% is powerfull in self-extinguishing. The higher br content is, the better the flame retardancy. So bromineated epoxy resin is widely used as flame retardant sealing materiall and flame retardant laminated plates and adhesives in the fields of electronics, electric appliance, ships and civil construction.
CYDB-450a80 is a bromineated flame-retardant epoxy resin special for FR-4copper clad laminates. This kind of resin is of high purity, strong reaction activeity. Good stability and tailor-made characters. Its condensate has adhesion, especially suitable for fr-4 copper clad laminates production when combined with dicyandiamide and imidazole curing agent.
