The effect of curing agent type on the gelation time of epoxy. The gelation time of epoxy and its different composites was estimated as a function of the cross-linker used—either IPD, TETA, or a combination of IPD/TETA in different ratios (25/75 or 75/25), as illustrated in Fig. 2.The measured gel times were 105 min for epoxy cured with IPD and 40 min for epoxy cured
One of the most widely used latent curing agents in both epoxy adhesives and composites is dicyandiamide, commonly referred to as dicy, the structure of which is shown in Table 1. Dicy, like other curing agents, is commonly micronized to reduce and control the particle size, which aids not only in dispersibility but also with reactivity.

When the amount of curing agent is insufficient, it is difficult to cure completely, and the curing agent is generally slightly excessive. When using a curing agent with a larger molecular weight, its dosage range can be slightly larger.

Curing agents are critical components of aqueous epoxy resin systems. Unfortunately, its uses and applications are restricted because of its low emulsifying yields. Epoxy resins are frequently used in electrical devices, castings, packaging, adhesive, corrosion resistance, and dip coating. In the presence of curing agents, epoxy resins become rigid and
The curing process brings several benefits to adhesives. It allows for faster bond formation, reducing assembly time and increasing productivity in industrial settings. Curing agents also enhance the bond''s integrity, preventing adhesive failure under mechanical stress or extreme environmental conditions.
Adhesives eliminate the need for mechanical fasteners, such as U-bolts and screws, and completely remove the stress points caused by these fasteners. By using our solar panel adhesives instead of mechanical fasteners, the need for constant maintenance and replacement inventory, along with the installation costs, is greatly reduced.
The connecting chains of the thermoset polymer are held together with the same primary covalent bonds as are the atoms in the main chain. Thus, the molecules are interlocked and do not slip easily by one another. Curing agents are, therefore, an important group of additives that influence both end-properties and curing.
Addition cure potting agents are supplied in two parts (A and B) that are mixed, usually in a 1:1 ratio. The materials are compatible with automated dispensing equipment. Solventless thick-section cure may be achieved quickly at room temperature or by heating, with minimal shrinkage.
In a closed container or concealed joint that is not exposed to atmospheric moisture, sealant cure will be slow to nonexistent. The material adhesion will only occur if the material is allowed to fully cure. Please ensure that the material joint is fully exposed to the environment.
If the material has not cured, or the sample does not demonstrate typical elastic behavior, contact DuPont. The peel adhesion test is the most effective daily test to verify sealant adhesion to a substrate. This simple screening test should be used as the daily test to verify adhesion of sealant to a substrate.
In the manufacture of solar modules, salvage or rework of damaged or defective units is sometimes required. It may be necessary to remove FortasunTM PV potting agents to allow repairs. This can be assisted by cutting away the defective areas or, in extreme cases, by using digestive stripping.
