Product Introduction

MP-S25 is an efficient hydrophobic and water-repellent agent used in cement-based mortars. It is a gray-white powder that enhances the water-repellency and durability of cement-based products. It is particularly suitable for applications where surface water repellency and internal hydrophobicity are required. Through a chemical reaction, it protects the surface and matrix of cement-based structures and mortars, preventing water penetration. MP-S25 is used in mortars, grouts, and building materials, and is easy to mix during cement mortar production. When mixed with water, it does not delay the wetting performance, cause air entrainment, or have a retarding effect. It has no adverse effects on surface hardness, bond strength, or compressive strength.
