The first batches of Araldite epoxy resins, for which the brand is best known, were made in Duxford, England in 1950. [1] Araldite adhesive sets by the interaction of an epoxy resin with a hardener. Mixing an epoxy resin and hardener together starts a chemical reaction that produces heat – an exothermic reaction. [2]
It went public as the Huntsman Corporation on the New York Stock Exchange NYSE: HUN in February 2005. Huntsman has grown through a series of acquisitions (with some divestitures) and today is a manufacturer and marketer of differentiated and specialty chemical products. In April 1994, Huntsman acquired the Texaco Chemical company for $1.1 ...
The main applications of polybenzoxazines resins are in fibre-reinforced plastic and as adhesives. They are substitutes of epoxy, phenolic and bismaleimide resins. Because of their superior resistance to chemicals, low flammability, and excellent heat stability, they are used for components that are exposed to high temperatures and corrosive media.
The resin and hardener part together is known as the "Binder". As the name indicates, in Fusion bonded epoxy coatings the resin part is an "epoxy" type resin. “Epoxy” or “Oxirane” structure contains a three membered cyclic ring — one oxygen atom connected to two carbon atoms – in the resin molecule. This part is the most reactive ...
Thermosetting plastics or silicone rubber gels are often used, though epoxy resins are also very common. When epoxy resins are used, low chloride grades are usually specified. [ 1 ] Many sites recommend using a potting product to protect sensitive electronic components from impact, vibration, and loose wires.
A key use is modifying the viscosity and properties of epoxy resins. As an Epoxy modifier it is classed as an epoxy reactive diluent. [8] which may then be formulated into CASE applications: Coatings, [9] Adhesives, [10] Sealants and Elastomers and composite materials. These uses include cationic polymerization reactions. [11] [12] The use of ...
The interior of a pocket calculator. The dark lump of epoxy in the center covers the processor chip. Epoxy resin formulations are important in the electronics industry, and are employed in motors, generators, transformers, switchgear, bushings, insulators, printed wiring boards (PWB), and semiconductor encapsulants. Epoxy resins are excellent ...
It is a mixture of epoxy resin, a common raw material for PCBs and BT resins. This is in turn a mixture of bismaleimide, which is also used as a raw material for PCBs and cyanate ester . Three cyano groups of the cyanate ester are trimerized to a triazine ring structure, hence the T in the name.
