Hydroxypropyl starch ether HPS First, the technical indicators: hydroxypropyl starch ethers (HPS) is a natural plant as raw material, through modification, a high degree of etherification, and then spray dried to obtain a white fine powder, without increasing plasticizer. It is completely different from the domestic starch or modified starch. Second, the application areas: as a cement-based products, gypsum-based products and calcium ash admixture product. And other buildings additives have good compatibility. And hydroxypropyl methyl cellulose ethers (HPMC) with the use of thickening can play a role in promoting the internal structure, better crack resistance and improve workability. By adding the modified starch ether can significantly reduce the amount of HPMC. Third, the application features: 1, good fast thickening capacity; medium viscosity, a certain retention; 2, the amount of small, low additive amount that can achieve high results; 3, to improve the ability of anti-falling material ; 4, to improve the operating performance of the material, make the operation more smooth. 5, to extend the opening hours of material; recommendations apply to the following materials: 1, all kinds of (cement, gypsum, ash calcium-based), the wall putty powder; 2, various types (tile, stone) adhesive; 3, all types of plasters and various types of plastering mortar. Fourth, Recommended dosage: 0.05% -0.1% while reducing methyl cellulose ether of 0.1%. V. Package: 25 kg / bag six, Storage: Store in a cool, dry place to prevent moisture penetration opened bags should be sealed again, when no more than one pallet stacking; storage does not exceed one year. 7, security and environmental protection: According Gefahrstoffverordnung standards, the product is non-hazardous. And dust protection (VBG No.119) relating to the accident prevention rules must be observed. The products are divided into ST1 levels. On request safety data sheets can be given.
