What is cyanate ester resin?
Cyanic esters (also called triazine or cyanate resins) are high performance thermosetting resins having reactive ring-forming cyanate groups (-O-C≡N). The cured resins form a 3D network of triazine rings and bisphenol.
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.
Is cyanate ester a polymer?
When the monomer contains two cyanate groups the resulting structure is a 3D polymer network.
Is cyanate ester a thermoset?
CYTESTER™ is a thermosetting resin containing –OCN groups. By repeating cyclotrimerization of three –OCN groups, cyanate esters form three-dimensional network polymers linked by triazine rings.
What is the formula of cyanate?
Cyanate is an anion with the structural formula [O=C=N]−, usually written OCN−. It also refers to any salt containing it, such as ammonium cyanate. It is an isomer of the much less stable fulminate anion [C−≡N+O]−.
How is ammonium cyanate formed?
Instead, the ammonium decomposes, forming ammonia and cyanic acid. The positive charge on the lead combines with two hydroxide molecules, and the negative charge on the cyanate forms with the ammonium to form ammonium cyanate.
How is ammonium cyanate inorganic?
Ammonium cyanate contains bbonds among Nitrogen and Hydrogen. Cyanate contains among Nitrogen and oxygen. It is an inorganic compound.
Where does vinyl ester come from?
Vinyl Ester Resin It is produced by the esterification of epoxy resin and an unsaturated monocarboxylic acid. It is used in transportation, building and infrastructure, military, energy and marine applications (pipelines, composite products and storage tanks).
Where does vinyl resin come from?
Vinyl is not a natural substance but is a synthetic man-made material. It is a type of plastic that is made from ethylene (found in crude oil) and chlorine (found in regular salt). When processed, both the substances are combined to form Polyvinyl Chloride (PVC) resin, or as is commonly referred to – Vinyl.
Which is used in the formation of epoxy resin?
Most common epoxy resins are produced from a reaction between epichlorohydrin (ECH) and bisphenol-A (BPA), though the latter may be replaced by other raw materials (such as aliphatic glycols, phenol and o-cresol novolacs) to produce specialty resins. The epoxy resins can be obtained in either liquid or solid states.
