1、Silane Coupling Agents

Many conventional coupling agents are frequently used in combination with 10-40% of a non-functional dipodal silane, where the conventional coupling agent provides the appropriate functionality for the application, and the non-functional dipodal silane provides increased durability.

2、Adhesion Promoters: Silane Coupling Agents

Coupling agents that function as adhesion promoters are chemicals that act at the interface between organic and inorganic surfaces to enhance adhesion between the two materials.

3、Oligomeric Silanes

Silane oligomers are multifunctional silanes which comprise different functional groups, e.g. vinyl, alkyl, amino groups and are characterized by a significantly reduced alcohol release (low VOC). Because of their higher flashpoint, they offer obvious advantages for handling, storage and production.

4、Silane Coupling Agents

What are Silane Coupling Agents? Silane coupling agents are compounds whose molecules contain functional groups that bond with both organic and inorganic materials. A silane coupling agent acts as a sort of intermediary which bonds organic materials to inorganic materials.

Silane Coupling Agent

SiSiB® PC1146 is a co-oligomeric diamino/alkylfunctional silane adhesion promoter that may be used over a wide range of applications.

Silane Coupling Agents

Silane coupling agents are organosilicon compounds that have two different functional groups, including one that reacts with organic materials and one that reacts with inorganic materials. This unique characteristic enables them to bond organic materials to inorganic materials.

2 Chemistry of Silane Coupling Agents

" Silane coupling agents may also be prehydrolyzed and applied to siliceous surfaces from aqueous solutions. Under these conditions, silanol groups of the coupling agent condense with hydroxyl groups of the mineral surface during drying operations.

Limitless silanes

A silane coupling agent will act as an interface between an inorganic substrate (such as glass, metal or mineral) and an organic material (such as an organic polymer, coating or adhesive) to bond the two dissimilar materials.
