Laboratory Investigation on Adhesives for Naval Facilities Construction.
Abstract
This report summarizes 3 years of laboratory findings on the comparative bonding strengths of adhesives to different construction materials and the effects of simulated weathering on adhesive bond strength. An adhesive used for construction should have a minimal tensile bond strength of 1,000 psi with the adherends being bonded. The selection of an adhesive should not be based on initial tensile strength along because some adhesives may weaken upon prolonged exposure to hot and cold temperatures, oxygen, or seawater. The strongest adhesives tested for most nonporous construction materials were two-part epoxies, peroxide-cured polyesters, peroxide-cured acrylics, and two-part urethanes. Although no single adhesive is suitable for bonding every type of material, a definite trend in general strength of the five classes of adhesives were discovered: chemically reacting, one- or two-component adhesives (epoxies, polyesters, urethanes) are generally stronger than solvent-based or hot-melt adhesives, which are much stronger than most aqueous-based adhesives (casein, fish, glue, hide glue). Originator-supplied keywords include: Adhesive bonding strength.
