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 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.
Limitless silanes
The silane coupling agent treatment on the filler can provide better bonding of the pigment or filler to the resin, improved mixing, increased matrix strength and reduced viscosity of the uncured sealant or adhesive.
Adhesion Promoters: Silane Coupling Agents
Silane coupling agents act in the interphase region, the area between an inorganic substrate and an organic substrate, and act as a bonding, or bridging, agent to improve the adhesion between the two dissimilar materials.
Silane Coupling Agent
There are three basic approaches for using silane coupling agents. The silane can be used to treat the surface of the inorganic materials before mixing with the organic resin or it can be added directly to the organic resin or holistic mixing (in organic-inorganic mixture).
