請(qǐng)問(wèn)乙烯基樹(shù)脂所用的固化劑和促進(jìn)劑都有哪些啊？有什么特殊要求嗎？哪為高人能給我指點(diǎn)指點(diǎn)？！不甚感激．

做防腐地坪的，請(qǐng)問(wèn)促進(jìn)劑該用多少濃度的合適？產(chǎn)生氣泡可能有影響的，怎么解決？謝謝指點(diǎn)．

王天堂先生不是寫的嗎，copy過(guò)來(lái)的吧，我看過(guò)您寫的這邊固化配方的文章，但是好像你這里解釋的只是僅僅富臣的樹(shù)脂的配方吧。

我用過(guò)樹(shù)脂，我覺(jué)得好像每家都有各自的特點(diǎn)，還是樹(shù)脂供應(yīng)商自己對(duì)自己的樹(shù)脂最了界了，還是直接問(wèn)樹(shù)脂供應(yīng)商吧。

因?yàn)樽龃龠M(jìn)機(jī)的一般都不做固化劑，做固化劑的一般又不作促進(jìn)機(jī)，這樣問(wèn)他們，他們也得做試驗(yàn)，反正樹(shù)脂廠家不可能對(duì)自己樹(shù)脂都沒(méi)有個(gè)推薦配方吧。
