uretaanialkylaatteja
Uretaanialkylaatteja, also known as urethane acrylates, are a class of oligomers widely used in the coatings and adhesives industry. These compounds are formed by the reaction of isocyanates with hydroxyl-functional acrylates or methacrylates. The resulting molecules typically contain multiple urethane linkages and acrylate functional groups. The urethane backbone provides flexibility and toughness, while the acrylate groups enable rapid curing through free-radical polymerization, often initiated by UV light or electron beam radiation.
The properties of uretaanialkylaatteja can be tailored by varying the structure of the isocyanates and hydroxyl-functional
