| Features of application | 1. In the gypsum system, the addition of PCE157L can achieve good flow performance, while the addition of water can be controlled at a very low level, reduce the porosity of gypsum products and improve the strength of gypsum products. 2, the product has a wide adaptability, suitable for most of the gypsum building materials, can be widely used in a variety of gypsum castable (such as phosphogypsum, desulfurization gypsum, high-strength gypsum and other materials). Improve the fluidity of gypsum slurry, easy construction, improve construction efficiency; 3, can be used to prepare high-density, high-strength gypsum products. 4. The product is green, non-toxic and harmless; |

| Usage | 1. Low dosage and high water-reducing rate. The recommended dosage is 0.2-0.5% (solid content) of the cementitious material, and the water-reducing rate can reach 25-40%; it is not an end product used in concrete production since the product is a water-reducing stock solution with a solid content of 50%. Recommend customers reduce the solid content of the product before use and determine the optimal dosage and performance through experiments. Other admixture products can be used in combination if necessary. 2. When users first use the product or change raw materials, please refer to the instructions according to the construction requirements plus conditions and conduct necessary trial mixing tests on the dosage along with methods to obtain the best technical and economic benefits; 3. The product cannot be mixed with a Naphth alene water-reducing agent to avoid affecting the performance. 4.It has a superior slump retention ability and must be mixed with water-reducing mother liquor. |
