Reactive additives are specialized chemical compounds that actively participate in chemical reactions within a formulation to modify or enhance the final properties of a product. Unlike conventional additives that are merely blended into formulations, reactive additives become an integral part of the chemical structure of the finished product. They are crucial for achieving specific functional properties such as improved adhesion, cross-linking, cure speed, and resistance to environmental factors.
