Abstract
<p>The effect of temperature change during curing of polyurethane sealants on the rate of strength development was investigated. Under a constant temperature environment, the curing rate of the sealant was accelerated at higher temperatures. However, after curing the sealant at a low temperature, the apparent curing rate became lower when the temperature was raised. It was found that at low temperatures, the amount of moisture required for the reaction was insufficient due to the reduced moisture diffusivity. Therefore, it is important to develop materials with a curing mechanism other than reaction with moisture to reduce defects in one-component sealants.</p>
