Product Code：SP8025
Product Name：1,1,3,3-TETRAMETHYL-1,3-DIPHENYLDISILOXANE
Product Introduction：
1,1,3,3-Tetramethyl-1,3-diphenyldisiloxane is a phenyl-substituted disiloxane. It acts as a key intermediate in silicone polymer synthesis for sealants and coatings. It provides excellent thermal stability for high-temperature applications and enhances hydrophobicity in surface modification. This colorless liquid is used in cosmetics, textiles, and electronics.
