N-(γ, dimethylin propyl)-γ-Aminopropylmethyldimethoxy silane

Some coupling agent may be good enough to soften and smoothen the fabrics, but they may also offer yellow stain to light color of fabrics，In the otherwise，the other may offer little yellow stain and good loose feeling to fabrics，but they are not good softeners and smoothening agents;  therefore, we need one kind of composite coupler with their characteristics.
HD-121 silane coupler is one kind of organosilane coupler modified both by secondary amino group and Tertiary amino group. It is a good finishing agent that can offer few yellow stain to light color of fabrics, and at the same time, it is a good softener, smoothening agent  and loosening agent of  fabrics. At present, HD-121 is one of best couplers.
