2. Epoxy - Wikipedia

   en.wikipedia.org/wiki/Epoxy

   Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. [1] The IUPAC name for an epoxide group is an oxirane.

3. Curing (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Curing_(chemistry)

   Epoxy resins are typically cured by the use of additives, often called hardeners. Polyamines are often used. The amine groups ring-open the epoxide rings. In rubber, the curing is also induced by the addition of a crosslinker. The resulting process is called sulfur vulcanization.

4. 3,4-Epoxycyclohexylmethyl-3',4'-epoxycyclohexane carboxylate

   en.wikipedia.org/wiki/3,4-Epoxycyclohexylmethyl-3...

   After a photopolymerization usually still a thermal post-curing is necessary for a complete reaction. [5] It is known that the reactivity of the monomer is lower than it could be, since the contained ester group can react with the reactive, polymerizing chain end and stabilize it. It therefore reacts significantly slower than other molecules ...

5. Thermosetting polymer - Wikipedia

   en.wikipedia.org/wiki/Thermosetting_polymer

   As reaction proceeds, larger and larger molecules are formed and highly branched crosslinked structures develop, the rate of cure being influenced by the physical form and functionality of epoxy resins and curing agents [3] – elevated temperature postcuring induces secondary crosslinking of backbone hydroxyl functionality which condense to ...

6. Waterborne resins - Wikipedia

   en.wikipedia.org/wiki/Waterborne_resins

   An epoxy resin system generally consists of a curing agent and an epoxy resin. Both the curing agent and the epoxy resin can be made waterborne. Solid epoxy resin (molecular weight >1000) dispersions are available and consist of an epoxy resin dispersed in water sometimes with the aid of co-solvents and surfactants. The resin backbone is often ...

7. J-B Weld - Wikipedia

   en.wikipedia.org/wiki/J-B_Weld

   J-B Kwik is a faster-curing two-part epoxy with medium-temperature resistance up to 300 °F (149 °C). Although not as strong or heat-resistant as J-B Weld, it has the same adhesion and does not shrink when hardening.
