PDMS(polydimethylsiloxane) is the abbreviation of polydimethylsiloxane, which is a kind of polymer material widely used in microfluidic and other fields. It has the advantages of low cost, simple use, good adhesion to silicon wafer and good chemical inertia. Silica gel for short.

Curing agent, also known as hardening agent, curing agent or stabilizer, is a substance or mixture that promotes or controls curing reaction. Resin curing is a process in which thermosetting resins undergo irreversible changes through chemical reactions such as condensation, ring closure, addition or catalysis, and curing is completed by adding curing (crosslinking) agents. Curing agent is an essential additive. Whether it is used as adhesive, coating or castable, curing agent needs to be added, otherwise epoxy resin cannot be cured. The types of curing agents have great influence on the mechanical properties, heat resistance, water resistance and corrosion resistance of cured products.
