三、产品特点
n 分子量高,在酸性介质中粘度很低,但在碱性条件下能获得很高的粘度,增稠后可以改善涂料的流动性和流平性,防止流挂；
n 使乳胶漆具有良好的机械稳定性,贮藏稳定性和冻融稳定性,具有良好的防霉、抗水，耐擦洗性能；
n 呈粘稠状液体，使用方便，是乳胶漆等各种水性涂料理想的增稠剂。
四、使用指南
用氨水调整涂料的pH值,使之达到8~9;LY-829请加水稀释使用,LY-829一般用量约占乳胶漆量的(0.2~1)%,以达到所需的乳胶漆成品粘度为准;在低速搅拌下,缓慢加入稀释后的LY-829,边搅拌边测涂料粘度,达到要求粘度后停止加入LY-829。
五、储运与包装
25kg或200kg塑料桶。产品应放在阴凉通风干燥的库房内,储存期一年。本品属非危险品。
