Optimal humidity is between 40 and 60 percent at room temperature. Higher humidity accelerates curing, but may impair the final strength of the bond. These adhesives offer flexibility, because they will bond almost all materials. After adhesive application, parts must be joined quickly, because polymerization begins within seconds. The fast curing times make these adhesives particularly suitable for bonding small parts.
Adhesives cured by humidity have high shear and tensile strength, and good aging resistance.
Moisture-cured adhesives include silicone formulations. Use Assembly Online's Adhesive Selector Guide to start your search for the right adhesive for your bonding needs.
