Application in Pigment & Filler

Main Performance Improvements:

Improve the compatibility of resin and filler

Improve the dispersion of fillers

Rheology of control system

Improve mechanical strength and electrical performance

Reduce expansibility and water vapor penetration

High reinforcing performance is formed between filler and resin

Greatly reduce the viscosity, increase the filling amount and improve the processing performance

Advantages

Silane coupling agents are widely used to treat fillers to improve the compatibility of resin and filler. Fillers and pigments treated by silanes can enjoy good dispersion in the resins, the system's rheology can be properly controlled and viscosity can be reduced. With silanes, more fillers and pigments can be added to the system, which can improve the mechanical strength and electrical performance of the system, reduce swelling and water vapor penetration, as well as the cost.

Silane coupling agents exhibit excellent advantages when used between organic polymers and inorganic fillers. It can improve the compatibility of resin and filler. It can improve the dispersion of the fillers, control the rheological property of the system, reduce the viscosity so the system's properties will be more like Newton fluid. Silane coupling agents can also improve the mechanical properties, such as flexural strength, tensile strength, impact strength and modulus of elasticity. Because it can increase the hydrophobicity ,so silane coupling agents help to improve electrical properties, especially when exposed to moisture. And it can increase filling volume, reduce swelling and water vapor penetration.
