Creep and temperature-dependent creep of one component polyurethane adhesives for green wood gluing
Abstract
Creep and temperature-dependent creep, characteristic of one component polyurethane adhesives for wet and green structural wood gluing 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.
