25 One Component Polyurethane Adhesives for Green Wood Gluing: Creep and Temperature-Dependent Creep
Download citation file:
Creep and temperature-dependent creep, characteristic of one component polyurethane adhesives for wet and green structural wood glueing such as in glulam are two different parameters. Testing of the best standards-approved commercial polyurethane adhesive for this purpose shows that while ambient temperature creep is limited this is not the case for temperature-dependent creep. The commercial adhesive formulation characteristics that minimize or enhance ambient temperature and temperature-dependent creep are identified.
