三、优点
n LY-228消泡能力强，适用于高粘度弹性涂料及各种厚浆涂料；
n LY-228对残存的微泡消泡效果好，使涂漆无弊病更加美观；
n LY-228对光泽影响小，最适合一次涂布的弹性涂料。
四、应用实例
n 普通内外墙涂料、高档腻子、平涂弹性及厚浆弹性涂料；
n 水性油墨；
n 水性粘着剂。
（最合适厚浆弹性涂料及高档腻子。）
五、使用指南
建议添加用量为涂料质量的0.1~1.0%。研磨阶段添加质量的30-50%，调漆阶段（加乳液之前）添加剩余的70-50%。长期贮存时，用前搅拌均匀，不影响使用效率。
n 厚浆型弹性建筑乳胶漆高档建筑腻子：推荐加入量为总配方的0.2~0.8%；
n 弹性平涂建筑乳胶漆水性油墨：推荐加入量为总配方的0.1~0.8%。
