HEPTAMETHYLTRISILOXANE
SILSOURCE™ SS-5017
Product Description
Heptamethyltrisiloxane is a linear organosilicon compound consisting of three silicon atoms connected by oxygen atoms, with seven methyl groups attached to the silicon atoms. Its unique molecular structure provides low surface tension, excellent spreading properties, and compatibility with a variety of formulations, particularly in coatings, personal care products, and agricultural applications.
