3M94底涂劑特殊應(yīng)用
3M94底涂劑是一類含鋅量大于74%(質(zhì)量分?jǐn)?shù))的底涂料,3M94底涂劑具有電位和導(dǎo)電等電化學(xué)行為,將其與導(dǎo)靜電涂料相容(配套)涂裝,可避免導(dǎo)靜電涂料與電位相對(duì)負(fù)的鋼材接觸形成電偶。
其涂膜為無(wú)機(jī)性物質(zhì),具阻燃性,最高耐熱性能為410℃,有機(jī)溶劑對(duì)其不產(chǎn)生溶脹和溶解作用,可用于碳鋼材質(zhì)的氧氣球罐和有機(jī)溶劑儲(chǔ)罐內(nèi)側(cè)的防護(hù)與導(dǎo)靜電,還可用于工作溫度410℃耐高溫有機(jī)硅涂料的底涂料,可提高涂層厚度,延長(zhǎng)涂層使用壽命。
3M94底涂劑以水為分散劑,無(wú)揮發(fā)性有機(jī)物質(zhì)(VOC),對(duì)環(huán)境不形成易燃易爆氣體極限濃度,可用于苯類和油類(原油除外)儲(chǔ)罐罐內(nèi)動(dòng)用明火檢修的場(chǎng)合。
該涂料呈堿性,對(duì)可溶鹽具良好的容忍性和陰極保護(hù)性,涂膜的使用壽命長(zhǎng),被廣泛用于大氣環(huán)境鋼結(jié)構(gòu)表面涂層的底涂料。
3M94 zinc primer is a kind of greater than 74% (by ​​mass) of the primer, primer end of 3M94 with potential and electrochemical behavior of conductivity, antistatic coating it with compatibility (supporting) coating, can be avoided antistatic coatings and relatively negative potential contact with the formation of galvanic steel.
The coating film is an inorganic material, a flame retardant, heat resistance is maximum 410 ℃, the organic solvent does not produce its swelling and dissolution, carbon steel can be used for the organic solvent of the tank and oxygen inside the tank with protection antistatic, but also for the working temperature 410 ℃ high temperature silicone primer coatings, the coating thickness can be increased to extend the life of the coating.
3M94 primer with water as a dispersing agent, no volatile organic compounds (VOC), the environment does not limit the formation of explosive gas concentrations can be used for benzene and oils (excluding crude oil) tanks tank use open flame overhaul occasions.
The coating was alkali-soluble salt with good tolerance and cathodic protection, long life of the coating, the atmosphere is widely used in the primer coating of steel.
