Silicone oligomers are resins of relatively low molecular weights whose molecules have a three-dimensional network structure. Owing to this structure, silicone oligomers can be used as resins on their own, as organic resin modifiers. They are used in a variety of applications and fields, and the diversity of products available has made them the focus of growing attention in recent years.
Owing to the low molecular weight, they have excellent compatibility.
Even in high temperature conditions, there is little evaporation and the active ingredients function as designed.
More effective than monomers, as there are more sites for reaction with the intended material.
When used with a curing agent, silicone oligomers cure at room temperature by reacting with moisture in the air.
Their relatively low molecular weights mean they will form very hard coatings.
Silicone oligomers especially those having methyl groups, form films with excellent water repellency.
