At present, there are two types of potting sealant for PCB board, which are epoxy resin potting sealant and silicone potting sealant. Epoxy resin potting sealant:
The use of potting glue sometimes does not solidify the phenomenon, and this phenomenon is known as the potting glue poisoning phenomenon. What are the reasons for silicone potting sealant poisoning and not curing? Today, let's talk about the causes and solutions of this phenomenon.
Silicone potting sealant is divided into a single component and two-component potting sealant according to the main material and additives and can be divided into condensation type and molding potting sealant according to the curing reaction. So today we're going to talk about the difference between silicone potting and condensation.
The electronic potting sealant is a kind of vulcanized silica gel, which can be cured at room temperature and cured by heating. Flame retardant and heat conduction.
Potting means that liquid polyurethane composite is mechanically or manually injected into the device with electronic components and circuits and solidified under normal temperature or heating conditions to become a thermosetting polymer insulating material with excellent properties.
