These cookies do not store any personal information. Curing is the process of maintaining satisfactory moisture content and temperature in freshly cast concrete for a definite period of time immediately following placement. In terms of processability of the resin this marks an important stage: before gelation the system is relatively mobile, after it the mobility is very limited, the micro-structure of the resin and the composite material is fixed and severe diffusion limitations to further cure are created. It has therefore been used for half a century as an accelerator in the formulation of amine-based hardeners for epoxy resins. As a consequence, there is an increasing tendency to try to reduce VOCs and substitute them, whenever possible. O VOC. Guest Post by Jeremy Pasatta, Advanced Polymer Coatings All the epoxy curing agents in the last set of blog posts (amines, mercaptans and anhydrides) required mixing of the epoxy with the curing agent just prior to curing and are therefore considered two component formulations.

These curing agents, known as phenalkamides, are synthesized using a polyamide as the starting amine in the synthesis scheme shown in Figure 1. Good heat resistance. In Europe, various regulations have been put in place to control the use of VOCs. An intermediate case involves a mixture of resin and additives that requires external stimulus (light, heat, radiation) to induce curing. However, formulators are still reluctant to switch to waterborne epoxy binders because they still encounter problems using those: waterborne systems tend to cure slowly; their application thickness is often limited; the final gloss of cured coatings is also known to be poor, because of an imperfect film formation process. Long gel time at ambient cure and high Tg if heat-cured. Curing is the process or operation which controls the loss of moisture from concrete after it has been placed in position, or in the manufacture of concrete products, thereby providing time for the hydration of the cement to occur.
