WebApr 2, 2014 · Cross-link is a bond which links one polymer chain to other. It can be ionic or covalent. Cross linking changes a liquid polymer into ‘solid’ or ‘gel’ by restricting the ability of movement. When polymer chains are linked together by cross-links, they lose some of their ability to move as individual polymer chains. WebJun 27, 2024 · Choosing the right crosslinking method for optimal coating performance. Put simply, crosslinking involves a chemical reaction between polymer chains to link them together. Picture a bowl of spaghetti. Each strand is separate and can be pulled out of the bowl (if it doesn’t slip out of your fingers). With crosslinking, there are chemical ...
