Crosslinkers have two or more functional groups each of which can bind to a chemical group. Crosslinkers can join two different molecules together or functionalize surfaces. Most crosslinkers are used at very small quantity, meanwhile they degrade quickly in the air. They often become expired before used up. Sofchip packages them in small container and with inert gas to reduce the chance of contacting air. All listed prices are based on per package and in USD
