Special features
– Anti Efflorescence/抗风化 By having nano meter particle size, AXILAT PR3500 provides excellent penetration power that seals porosity of substrate and blocks the salt migration thus we call it as anti efflorescence primer./ 由于具有纳米级 的粒径，AXILAT PR3500 提供优良的渗透力以密封基材的细孔，阻隔 盐的迁移，因此我们称之为抗风化底漆。 – Consolidation Power/巩固力 By having good wettability, binding power combined with excellent penetration power, it consolidates chalky substrate that makes it possible to be recoated./由于具有良好的润湿性，粘合力和优良的渗透力，它巩 固了白垩表面使之可以被重涂。

Apply a chalky coating on substrate, which thickness varies from 1*85 microns to 5*85 microns./涂刷白垩涂料在底物上，它的厚度从1*85微米到5*85微米。
– This may be obtained by applying from one to five coats over the Surface, leaving each time a part of the previous layer uncoated. Drying time between layers is 24 hours at 23 ℃ ／50 % R.H./这可以通过涂刷１到５道涂层来获得，每次都留有前 道的部分不涂刷，两道涂刷之间在23 ℃ 下干燥24小时。 – Apply primer to be tested; different primers can be tested next to each other./测试底 漆，不同的被测底漆可互相挨着。 – Let it dry for 24 hours, apply a pressure sensitive tape and then peel off.／干燥样本 24小时，贴上一条对粘力灵敏的胶带，然后剥离。 – Visual evaluation on how many chalky coating layers are peeled off gives an idea of the consolidation power, which is a combination of penetration and binding power scale from 0 to 5 (five being excellent with no chalky coating pick up) ./目测大约多 少的白垩涂层被剥离，给出一个巩固力大少的判断,它可以用0到５数值指示出 渗透性和粘合力的综合性能。
