Polyurethane

Polyurethane potting adhesive, also known as PU potting adhesive, is generally a two-component, divided into the main agent and curing agent. The main components are polydiisocyanate and polyether polyol, which are crosslinked and cured to form polymers in the presence of a catalyst (triethylenediamine). Polyurethane potting adhesive has good adhesive properties, insulation properties, and weather resistance, and its hardness can be changed by adjusting the ratio of diisocyanate and polyether polyol.
