3M94底涂剂特殊应用
3M94底涂剂是一类含锌量大于74%(质量分数)的底涂料,3M94底涂剂具有电位和导电等电化学行为,将其与导静电涂料相容(配套)涂装,可避免导静电涂料与电位相对负的钢材接触形成电偶。
其涂膜为无机性物质,具阻燃性,最高耐热性能为410℃,有机溶剂对其不产生溶胀和溶解作用,可用于碳钢材质的氧气球罐和有机溶剂储罐内侧的防护与导静电,还可用于工作温度410℃耐高温有机硅涂料的底涂料,可提高涂层厚度,延长涂层使用寿命。
3M94底涂剂以水为分散剂,无挥发性有机物质(VOC),对环境不形成易燃易爆气体极限浓度,可用于苯类和油类(原油除外)储罐罐内动用明火检修的场合。
该涂料呈碱性,对可溶盐具良好的容忍性和阴极保护性,涂膜的使用寿命长,被广泛用于大气环境钢结构表面涂层的底涂料。
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.
