Fillers can greatly affect the properties of adhesives, and this research aimed at enhancing
the performance of adhesives by using different concentrations of fillers. This paper
describes the influence of using recycled polyurethane particles (powder of particle size
from 10 µm to 50 µm) as a filler on some properties of polyurethane adhesives for the gluing
of wood. Two kinds of one-component, moisture-curing polyurethane adhesives were used.
The observed properties were the contact angle between the wood and adhesive droplet …
