What is 2,2-Bis-(4-cyanatophenyl)propane with CAS 1156-51-0?
2,2-Bis-(4-cyanatophenyl)propane (CAS 1156-51-0), also known as Bisphenol A cyanate ester, is a high-performance thermosetting resin monomer widely used in advanced composite materials and electronic encapsulation. It features excellent thermal stability, low dielectric constant, and superior mechanical strength, making it a key material in aerospace, electronics, and high-performance composites.
As a difunctional cyanate ester derived from Bisphenol A, it undergoes cyclotrimerization reactions to form triazine ring networks, resulting in highly crosslinked structures with outstanding thermal and dielectric properties.

Toepassing
1. Advanced Composite Materials
Bisphenol A cyanate ester (CAS 1156-51-0) is widely used in carbon fiber composites, glass fiber composites, and aerospace-grade laminates. Its crosslinked triazine structure provides:
-
High glass transition temperature (Tg > 250°C)
-
Excellent dimensional stability
-
Low moisture absorption
-
Superior adhesion to reinforcing fibers
These properties make it ideal for aerospace structures, satellite components, and high-performance automotive composites.
2. Electronic and Electrical Applications
Owing to its low dielectric constant and excellent thermal endurance, 2,2-Bis-(4-cyanatophenyl)propane is a key material in:
-
Printed circuit boards (PCBs)
-
Semiconductor encapsulation resins
-
High-frequency electronic substrates
-
Adhesive formulations for electronic packaging
Its low outgassing and minimal dielectric loss ensure stability in microelectronic and communication equipment.
3. Adhesives and Coatings
The reactive cyanate ester groups enable self-polymerization or copolymerization with epoxy or bismaleimide resins. This improves:
-
Crosslink density and mechanical strength
-
Chemical and solvent resistance
-
Long-term heat resistance
Therefore, it’s often used in heat-resistant coatings, adhesive systems, and structural composites requiring durability under extreme environments.
