Moisture-Cure Polyurethane Wood Adhesives: Wood/Adhesive Interactions and Weather Durability
This project addresses two main subjects of moisture-cure polyurethane (PUR) wood adhesives: wood/PUR interactions and structure-property behavior emphasizing on weather durability. For these purposes, one simplified model PUR (MPUR) and three more commercially significant PURs (CPURs) with …

Investigating Differences in Douglas-fir and Southern Yellow Pine Bonding Properties
… using ASTM-D2559 with two adhesives, a one-part moisture cure polyurethane (PU), and a two-part ambient curing phenol-resorcinol-formaldehyde (PRF). Shear stress for southern yellow pine was affected the most by the type of growth regions at the bond (juvenile to mature wood) and the assembly …

Fundamental Analysis of Wood Adhesion Primers
… adhesion and enhances bond durability against moisture exposure. In an effort to improve understanding of the HMR mechanism of action, this work compared HMR with two other chemical treatments investigated as wood primers: alkyl-HMR (a-HMR), an HMR variant having reduced crosslink density, and …

Characterization of Mixed-Mode Fracture Testing of Adhesively Bonded Wood Specimens
… as adherends and two different adhesives: a moisture-cure polyurethane (PU) and a phenol/resorcinol/-formaldehyde (PRF) resin. The geometry tested in the study was the double cantilever beam that, in a dual-actuator load frame, can be used for testing different levels of mode-mixity. The …
