Hydroxypropyl Starch Ether Product Description Hydroxypropyl starch ether is a starch-based additive designed for dry mortars in the construction industry, imparting unique properties to cement and gypsum-based products. Hydroxypropyl starch ether , which has a similar chemical structure to hydroxypropyl methylcellulose (HPMC), not only provides similar functions to hydroxypropyl methylcellulose (HPMC) , but also has good compatibility with other building aids. Capacitance. Used in conjunction with hydroxypropyl methylcellulose (HPMC), hydroxypropyl starch ether can play a better thickening effect, with better crack resistance and processability. It works well in neutral and alkaline conditions and is compatible with other additives in gypsum or cement-based building materials. The cost of mortar formulations can be significantly reduced by adding starch ethers. Specification of Hydroxypropyl Starch Ether Appearance white or quasi-white powder    Viscocity (5% solution 20...

Silicone Hydrophobic Powder Product Description Silicone hydrophobic powder  is highly efficient, silane-siloxance based powdery hydrophobic agent, which composed silicon active ingredients enclosed by protective colloid. This easily used admixture makes such materials more hydrophobic and resistant to the structural damage or appearance problems caused by excess moisture and sunlight (UV) degradation. Specification Appearance White free flowing powder Silicone content(%) 50 min Bulk density (g/l) 550~600 Moisture content (%) 2 max Package 25kg/bag Properties 1. Supplied as free-flowing granules, which are easily mixed dry 2. Easily blended into material formulations during manufacturing or used as an admixture at the job site. 3. Adds hydrophobic properties to both exterior and interior cement-based materials, including concrete, cement, joint fillers, stucco, EIFS, plaster, grout, mortar, and more. 4. Delivers longer-term performance than stearate-based powders More information a...
