1.It can be used as a surface modifier to generate hydrophobicity (e.g. on concrete, glass, inorganic pigment or mineral fillers).
2.When diluted with an appropriate solvent, it can be used in the formulation of water repellent products. Upon proper application, the formulated product will penetrate and provide water proofing performance.
3.It chemically reacts with cementitious substrate. Treated substrates are hydrophobic and retain their original appearance.
