Coupling Agents

The principle is simple: With better interfacial bonds between dissimilar materials, the desirable properties of each component can be carried throughout a composite material. This means that component properties are maintained or, in some cases, enhanced. Putting this principle to work for our customers, Momentive has developed silane coupling agents that can help optimize mechanical, electrical, thermal and other properties of an end product.

Additionally, these agents can help avoid some of the drawbacks of traditional coupling agents, such as premature vulcanization of a tire compound, or loss of flexural strength in a glass-reinforced composite exposed to high heat and moisture.

Momentive offers advanced agents for coupling resins with minerals, fiber reinforcements and other fillers. As part of it’s diverse portfolio of silane coupling agents that can improve: can help improve:

  • Resiliency of insulation batts
  • Wet strength retention
  • Thermal and electrical properties
  • Integrity, protection and handling of reinforcing fibers
  • Composite strength and toughness
  • Abrasion resistance
  • Rolling resistance, traction and wear

 

Processing characteristics of our advanced coupling agents can lead to higher efficiencies, and thus lower costs in manufacturing. Enhanced shelf stability, rheology control, filler dispersion, as well as fewer mixing steps and faster cure, all are typical benefits that our coupling agents offer customers to help improve their bottom lines. Further, some of our coupling agents are especially environmentally advantageous offer limited VOC (volatile organic compound) emissions, virtually eliminating ethanol release during processing and when mineral-reinforced rubber products are used, or providing halogen-free formulated flame retardancy (HFFR). 


Momentive's silane brand families, such as Silquest,* e-free* and NXT* silanes, offer our customers the potential to help increase energy efficiency by reducing the amount of agent required to achieve desired performance levels.


Momentive's coupling agents are frequently specified for applications requiring exceptional bonds between inorganic substrates and organic polymers including:

  • Tires
  • Shoe soles
  • Wire and cable products
  • Belts and hoses
  • Grommets
  • Flooring
  • Fiber-reinforced composites and insulation
  • Filled polymer resin applications
