DRY POWDER COMPOSITION, PUTTY COMPOSITION OBTAINABLE FROM SUCH COMPOSITION, AND SUBSTRATE COATED WITH SUCH PUTTY COMPOSITION
The invention relates to a dry powder composition comprising 4% to 20% by weight of cement, wherein the cement is one selected from the group consisting of Portland cement, aluminous cement, and sulfate aluminate cement; 4% to 12% by weight of gypsum; 1.5% to 4.0% by weight of re-dispersible binder polymer particles; 0.02% to 0.04% by weight of a retarder; 0.02% to 0.05% by weight of a viscosity modifying agent selected from the group consisting of xanthan gum, dextran, welan gum, gellan gum, diutan gum, pullanan, and mixtures of two or more thereof; 0.15 to 0.35% by weight of a cellulose ether; and 65% to 85% by weight of a filler having particles with a particle size distribution with a D50 value in the range of from 12 to 300 um, wherein all percentages by weight are based on the total weight of the composition.The invention further relates to a putty composition obtainable by adding water to such dry powder composition and to a substrate coated with a putty layer deposited from such putty composition.
本发明涉及一种干粉组合物，包含4‑20重量％水泥，其中该水泥选自波特兰水泥、高铝水泥和硫铝酸盐水泥；4‑12重量％石膏；1.5‑4.0重量％可再分散基料聚合物颗粒；0.02‑0.04重量％缓凝剂；0.02‑0.05重量％粘度改性剂，选自黄原胶、葡聚糖、韦兰胶、结冷胶、定优胶、普鲁兰以及其中两种或更多种的混合物；0.15‑0.35重量％纤维素醚；以及65‑85重量％具有粒度分布D50值在12‑300μm范围内的颗粒的填料，其中所有重量百分数基于该组合物的总重量。本发明进一步涉及一种可以通过将水加入该干粉组合物中得到的腻子组合物以及一种涂有由该腻子组合物沉积的腻子层的基材。
