| Résumé : |
Epoxy adhesives offer excellent properties but are intrinsically brittle due to their high crosslink density. To increase toughness, reactive liquid polymers (RLPs) are often added. Selection of the correct reactive end group is critical. New RLP chemistries are discussed that improve performance at room temperature and in low-temperature applications. |
