Product features and uses:
1. Waterproofing agent and protective agent for construction: KH-581 or its diluent has good protective effect for concrete and stone protection. It can form a dense water-repellent layer on the surface of the substrate to inhibit the penetration of water, thereby effectively preventing the erosion of the substrate by water seepage, sunlight, acid rain and seawater, and extending the service life of the building.
2. Surface treatment agent for inorganic fillers: This product can significantly improve the dispersion and compatibility of fillers in plastics, rubber, and resins, and is suitable for most inorganic powder materials and plastics, rubbers, and resins.
3. Dispersant for pigments: The treated pigments have good dispersibility and hydrophobicity, and are not easy to settle
