2. Epoxy - Wikipedia

   en.wikipedia.org/wiki/Epoxy

   Hardeners which show only low or limited reactivity at ambient temperature, but which react with epoxy resins at elevated temperature are referred to as latent hardeners. When using latent hardeners, the epoxy resin and hardener may be mixed and stored for some time prior to use, which is advantageous for many industrial processes.

3. 4,4'-Diaminodicyclohexylmethane - Wikipedia

   en.wikipedia.org/wiki/4,4...

   In the epoxy industry it is often referred to as PACM, short for para-diamino­dicyclohexyl­methane. It is used as a curing agent for epoxy resins [1] It finds particular use in epoxy flooring. [2] Another use is to produce diisocyanates, which are precursors to polyurethanes. The mixture is a colorless solid, but typical samples are yellowish ...

4. J-B Weld - Wikipedia

   en.wikipedia.org/wiki/J-B_Weld

   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.

5. Adipic acid dihydrazide - Wikipedia

   en.wikipedia.org/wiki/Adipic_acid_dihydrazide

   Adipic acid dihydrazide (ADH) is a chemical used for cross-linking water-based emulsions.It can also be used as a hardener for certain epoxy resins. [2] ADH is a symmetrical molecule with a C4 backbone, and the reactive group is C=ONHNH 2.

6. Tetraethylenepentamine - Wikipedia

   en.wikipedia.org/wiki/Tetraethylenepentamine

   It is primarily used as a curing agent or hardener in epoxy chemistry. This can be on its own or reacted with tall oil fatty acid (TOFA) and its dimer to make an amidoamine. [2] This amidoamine is then used as the curing agent for epoxy resin systems. TEPA is a pentadentate ligand in coordination chemistry.

7. 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.
