Cyanate esters are chemical substances in which the hydrogen atom of the phenolic OH group is substituted by a cyanide group. Cyanate esters based on a bisphenol or novolac derivative are used in the production of resins.
What is cyanate ester used for?
They are used for a variety of applications including spacecrafts, aircrafts, missiles, antennae, radomes, microelectronics, and microwave products. Cyanate esters are formed via the reaction of bisphenol esters and cyanic acid that cyclotrimerize to produce triazine rings during a second cure.
What is bismaleimide resin?
Bismaleimide resins are known for their high-strength and high-temperature performance. They are widely used as matrix resins for high-performance (fiber-reinforced) composites in electronic and aerospace industries. They also find applications as high performance adhesives.
Is cyanate toxic?
The cyanate ion is relatively non-toxic in comparison with cyanides. Use of this fact is made in cyanide decontamination processes where a permanganate oxidation converts toxic cyanide to safer cyanate. Cyanate can be decomposed by the enzyme cyanate lyase (or cyanase), which is found in bacteria and plants.

Where are Bismaleimide BMI resins used?
Thermosetting bismaleimide (BMI) resins have been widely used as a matrix for advanced composites in aerospace and astronautics. BMI resins possess excellent thermal and oxidative stability, as well as electrical and mechanical properties and a relatively low propensity for moisture absorption.
Are cyanate and cyanide the same?
Cyanate (OCN–) is related to cyanide and is often found in waters that contain cyanide. Cyanate originates from the oxidation of cyanide but exhibits different chemical, analytical, treatment, and toxicity characteristics.
What is difference between cyanate and cyanide?
As nouns the difference between cyanate and cyanide is that cyanate is (chemistry) any salt or ester of cyanic acid while cyanide is (chemistry|countable) any compound containing the -c≡n radical or the c≡n-1 anion.
