Araldite epoxy resin is commonly used as an embedding medium for electron microscopy. [9] Some Flamenco guitarists (e.g. Paco Peña) use it to reinforce their fingernails. [10] Brian May used it to seal some of the pickups in his homemade Red Special guitar to reduce microphonic feedback. [11]
Such materials are often diluted with styrene and converted to resin. Epoxy resins are thermosetting polymers , which are crosslinked using hardeners (curing agents). The most common curing agents for epoxy resins are polyamines , aminoamides, and phenolic compounds.
Driving.co.uk ranked it #14 on their list of the 23 ugliest cars ever made, [136] Auto Express ranked it #5 on their list of the ten ugliest cars ever made, [137] and Drive.com.au included in their article on the worst cars of the 20th century, calling it "one of the silliest-looking cars of the century".
Resorcinol glue, also known as resorcinol-formaldehyde, is an adhesive combination of resin and hardener that withstands long-term water immersion and has high resistance to ultraviolet light. [ 1 ] [ 2 ] The adhesive, introduced in 1943, has been popular in aircraft and boat construction.
Consumer Reports (CR), formerly Consumers Union (CU), is an American nonprofit consumer organization dedicated to independent product testing, investigative journalism, consumer-oriented research, public education, and consumer advocacy.
The epoxy value is defined as the number of moles of epoxy group per 100g resin. So as an example using an epoxy resin with molar mass of 382 and that has 2 moles of epoxy groups per mole of resin, the EEW = 382/2 = 191, and the epoxy value is calculated as follows: 100/191 = 0.53 (i.e. the epoxy value of the resin is 0.53).

Vinyl ester resin is an example of a synthetic resin. [1] Synthetic resins are industrially produced resins, typically viscous substances that convert into rigid polymers by the process of curing. In order to undergo curing, resins typically contain reactive end groups, [2] such as acrylates or epoxides.
