Mechanical activation of curing agent (AlPO4) was adopted to improve the adhesive strength of solar reflective coatings in this study. AlPO4 was characterized by Laser Particle Size Analyzer, X-ray Diffractometer, Scanning Electron Microscope and Zeta Potential Meter.
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.
Why are curing agents important?
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.
What are addition cure potting agents?
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.
Can sealant cure in a closed container?
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.
How do I repair a damaged solar module?
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.
