Siwin is a leading manufacturer and supplier of organosilanes for over 15 years.

Siwin is always devoted to developing easy to use silane products, such as silane oligomers.

Silane oligomers are large molecular compounds formed by the connection of multiple silane molecules, possessing complex chemical structures and excellent physicochemical properties. Compared to individual silane molecules, silane oligomers have higher stability and heat resistance, and are widely used in fields such as rubber, plastics, adhesives, and coatings.

The preparation of silane oligomers can be carried out through various methods, including hydrolysis/condensation reactions, polymerization reactions, etc. These methods allow for the control of chain length and functionality, thereby obtaining silane oligomers with specific properties.

Siwin silane oligomers are composed of multiple connected silane molecules, making their chemical structure more complex. They typically exhibit higher stability and lower chemical reactivity, suitable for environments requiring high stability and heat resistance. Additionally, silane oligomers possess excellent adhesion properties and chemical stability, allowing them to perform exceptionally well in material preparation and surface treatment.

There are various types of silane oligomers, including epoxy-based silane oligomers and mono and di-amino silane oligomers, etc. Different types of silane oligomers have distinct characteristics and application areas:

Epoxy-based Silane Oligomers: Such as Siwin-OP200, mainly used as adhesion promoters, crosslinkers, and dispersants for inorganic pigments in water-based and oil-based coatings and adhesives. It offers better hydrolytic stability, lower VOC emissions, and faster reaction speeds.

Amino Silane Oligomers: Such as Siwin-A146, primarily used in paints, coatings, inks, adhesives, and sealants to improve adhesion to inorganic materials like glass and fiberglass, as well as plastics. Suitable for polymers reactive with amines, such as silicone sealants and two-component polyurethanes.
