product description:

The linear modified amino silicone oil produced by our company is used for smooth and soft finishing of textiles. The molecular weight distribution is uniform, which can give the fabric a soft, smooth and waxy feel. It has reactive groups inside and can react with active groups on the fiber to form a three-dimensional network structure.

Application method:

Before soft and smooth finishing, it must be emulsified into a microemulsion with a solid content of 30% or less. Emulsification can be carried out in a shear mixer or reactor. The emulsified microemulsion is a stable liquid with transparent blue light;

Precautions:

1. Avoid contact with strong acids and alkalis, metal chromium compounds and oxidants;

2. Close the container when disabled;

3. When used in the long-rolling padding process, it needs to be mixed with other auxiliary agents for preventing sticking rollers. Before use, please do the padding stability test.
