GLOSSARY TERM
Cross-Linking
Chemical bonds formed between polymer chains in a coating, increasing its strength and durability.
INFO
What it is
Cross-linking is the chemical process where polymer chains in a coating bond together as it cures, forming a dense, interconnected film. It is what hardens many coatings into their final durable state.
Why it matters
Cross-linked films are stronger, more chemical-resistant, and more durable than coatings that simply dry by solvent evaporation. The process is key to the performance of high-end protective systems.
Where it is used on a project
Central to two-pack coatings such as epoxies and polyurethanes, used where toughness and resistance matter, including metalwork, floors, and demanding environments.
How NECC approaches it
When we use multi-component coatings, we mix and apply them correctly so they cure and cross-link as intended, achieving the full strength and durability the product is designed for.

FAQ's
What is cross-linking in a coating?
It is the chemical bonding between polymer chains as a coating cures, which is what turns it from a wet film into a hard, durable layer.
Which coatings cross-link?
Two-pack products such as epoxies and polyurethanes rely on it, which is why they form especially tough, chemical-resistant films.
