Abstract
Reactive urethane-acrylates of specific composition have been designed and developed as thermoplastic precursor macromolecules for yielding high performance thermoset structural adhesives with bond strength retention at temperatures up to 220°C. These products are members of a range entitled ‘Xenacryl Reactive Adhesives’ (XRA) and their development was directed at meeting the following requirements in a single component system:
-
(a)
application temperature below 120°C and preferably at 60°–100°C,
-
(b)
thermoplastic behaviour during application,
-
(c)
zero volatile emission,
-
(d)
non-hazardous during handling, storage and application,
-
(e)
stability towards moisture and under storage,
-
(f)
control over melt viscosity,
-
(g)
control over rate of solidification,
-
(h)
control over rate and extent of cross-link formation during post curing, (i) choice of cross-linking conditions.
