The effect of relative humidity on the curing of alkoxysilane functional alkyds and reactive diluents was evaluated. Alkoxysilane functional alkyds and tung oil-based reactive diluents were synthesized and used as additives in varying amounts in alkyd coatings. Looking at modified alkyd versus modified reactive diluent allows for the comparison of the humidity effect on high and low molecular weight alkoxysilane functional additives. The coatings were cured at 25 and 75% relative humidity and evaluated for drying time, coating and tensile properties, and gel content. It was found that at higher humidity, the alkoxysilane-containing samples improved properties significantly when compared to the control alkyd.

评估了相对湿度对烷氧基硅烷官能醇酸树脂和活性稀释剂固化的影响。合成了烷氧基硅烷官能醇酸树脂和桐油基活性稀释剂，并将其用作醇酸涂料中不同量的添加剂。查看改性醇酸树脂与改性活性稀释剂，可以比较湿度对高分子量和低分子量烷氧基硅烷功能添加剂的影响。涂层在 25% 和 75% 的相对湿度下固化，并评估干燥时间、涂层和拉伸性能以及凝胶含量。发现在较高湿度下，与对照醇酸树脂相比，含烷氧基硅烷的样品显着改善了性能。
