1. Hydroxy silicone oil is used as leather finishing agent

The film-forming material in the coating layer has a great influence on the physical properties of the finished leather, especially the top coating gives the finished leather surface water resistance, solvent resistance, mechanical damage resistance and other properties, which play a decisive role in the appearance of the leather.

Due to the introduction of hydrophilic ionic groups in the molecular chain of polyurethane, the water resistance of its coated leather is poor. This shortcoming can be improved by adding hydroxy silicone oil. Hydroxy silicone oil is a kind of material with good hydrophobicity, air permeability and weather resistance. When it is used in the synthesis and modification of water-based polyurethane, the leather obtained after finishing will have better wet rub resistance and smoother hand feeling.

2. Hydroxy silicone oil is used as leather backing agent

When some leather back covers are painted, the coating will peel off because the coating is not resistant to the impregnation of the solvent in the shoe adhesive. Hydroxy silicone oil can be used for its good air permeability, weather resistance, corrosion resistance and non-toxicity, effectively solving the peeling phenomenon when the back cover is painted.

3. Hydroxy silicone oil is used as textile auxiliaries

In the textile and garment industry, it can be used as fabric softener, lubricant, waterproof agent, finishing agent, etc. In order to meet the high-end needs of textiles, chemical products are also constantly developing hydroxy silicone oils that can be used in baths with various functional additives such as waterproofing agents, flame retardants, antistatic agents, and color-fixing agents, and have a good feel.

In addition to the functionalization of textiles as additives in textiles, hydroxy silicone oil products will also be applied to other fields in textiles, such as the combination of silicone and polyurethane to form the coating of the fabric; the polymerization of silicone and acrylic to form the printing of the fabric; organic The combination of silicon and organic fluorine forms a waterproof coating on the surface of the fabric, etc.

4. Hydroxy silicone oil is used in coating industry

Hydroxy silicone oil can improve the production process of the coating, maintain the storage stability of the coating, improve its construction process, improve the product quality, and give the coating some special functions, such as leveling, anti-scratch, anti-blocking, pigment dispersion, smoothing, surface special effects, wetting, hydrophobicity, defoaming and anti-foaming, etc.

Now hydroxy silicone oil has become an indispensable component in coatings. Reasonable and correct selection of hydroxy silicone oil additives can effectively reduce costs and improve benefits. Depending on the coating system, the hydroxy silicone oil additives used are also different, but each additive has a variety of effects and can sometimes be used in other systems.
