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]
J-B Weld epoxy is a two-part adhesive that can bond various surfaces and withstand high temperatures up to 500 °F (260 °C) constantly and 600 °F (316 °C) for short periods. It is water-resistant, petroleum/chemical-resistant, acid-resistant, and resists shock, vibration, and temperature fluctuations.
The left component is Epoxy Base Resin and the right one is Epoxy Hardener. Both are to be mixed thoroughly in equal quantity to get epoxy putty. Epoxy putty refers to a group of room-temperature-hardening substances used as space-filling adhesives. Exact compositions vary according to manufacturer and application.
A key use is as a catalyst for epoxy resin chemistry. It can be used as a homopolymerization catalyst for epoxy resins and also as an accelerator with epoxy resin curing agents. It is then further used in coatings, [5] sealants, composites, [6] adhesives [7] and elastomers. It has been stated that it is probably the most widely used room ...
4,4'-Diaminodicyclohexylmethane is the name for organic compounds with the formula CH 2 (C 6 H 10 NH 2) 2.It is classified as a diamine.In the epoxy industry it is often referred to as PACM, short for para-diaminodicyclohexylmethane.
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.
