841涂料是一种以碱金属硅酸为基料,加入固化剂、填充料和颜料等配制成的无机建筑涂料,其主要技术参数为: 附着力>1.4kgf/em~2;耐水性>30天,耐热性为80℃时,10小时涂膜无变化,耐低温性为-2℃时涂料无冻结现象;耐紫外线试验20小时涂膜无变化,耐碱性大于500小时;遮盖力<400g/m~2。涂料冻融试验表明:冻融7次,涂料性质不变。可供刷涂和喷涂。用于外墙装饰,只要合理施工,可不受气侯影响。一、841涂料的适用墙面 841涂料对于砖墙、水泥砂浆面层、混合砂浆面层、混凝土面层都可以涂刷,有良好的附着性。
841 coating is an inorganic building paint formulated with alkali metal silicic acid base, adding curing agent, fillers and pigments. Its main technical parameters are: Adhesion> 1.4kgf/em~2; Water resistance> 30 Days, when the heat resistance is 80°C, there is no change in the coating for 10 hours, the coating has no freezing when the low temperature resistance is -2°C, the coating does not change in the UV resistance test for 20 hours, and the alkali resistance is more than 500 hours; the hiding power 400g/m~2. The freeze-thaw test of the coating shows that the properties of the coating remain unchanged after 7 freeze-thaw cycles. For brushing and spraying. For exterior wall decoration, as long as reasonable construction, can be affected by weather. First, the 841 coating for the wall 841 coating for brick walls, cement mortar surface, mixed mortar surface, concrete surface layer can be brushed, with good adhesion.
