PU waterproofing agent

【Performance characteristics】

This product is a kind of organic silicon surfactant. Because of its special molecular structure, this material has good hydrophilicity. Its waterproof mechanism is to capture water and react with it, so as to eliminate the influence of water on the system. Purpose. This product has the functions of leveling, reducing viscosity, defoaming, wetting, emulsifying, softening and increasing slip. In the production process of synthetic leather, it can overcome the bad condition of water spots, shrinkage, craters and color stripes on the surface of PU leather caused by water in the tanning slurry or high air humidity. At the same time, this product also participates in the reaction of tanning materials and is fixed in the leather material, making PU leather more soft and smooth, improving leveling and gloss, and improving anti-blocking properties.

【Technical Index】

Appearance: yellowish transparent liquid (may be cloudy or solidified at low temperature)

Solid content: 100%

Solubility: DMF, alcohols, ketones, toluene, esters are completely miscible, and mostly miscible with water.

Surface tension: 28～30

【Applications】

Used in Pu resin, it can capture the water accidentally introduced into the coating resin, avoid the quality defect of Pu leather caused by improper reaction, improve the leveling of the resin, reduce the phenomenon of shrinkage and pinholes, and improve the surface feel of the finished leather And luster, increase the wear resistance of fabrics, have anti-adhesion and help release effects.

【Dosage】

The dosage of waterproofing in the resin is 0.2%-0.5%, and the dosage of Pu fabric additives for clothing is 0.8%-1.5%. Generally, it is diluted 10 times with solvent in advance, and then it can be conveniently added to the system. Adjust according to the moisture content of raw materials and air humidity. This product is especially suitable for use in wet areas or in the production of synthetic leather in wet seasons.

【Packaging, storage and transportation】

1. This product is packaged in 50KG plastic barrels and 200KG barrels.

2. It should be stored in a dry, ventilated and cool place at room temperature. If left for too long, the viscosity tends to increase.

3. Storage and transportation as non-dangerous goods.
