Polyurethane adhesive refers to an adhesive containing urethane groups (-NHCOO-) or isocyanate groups (-NCO) in the molecular chain. Polyurethane adhesives are divided into two categories: polyisocyanate and polyurethane. Polyisocyanate molecular chain contains isocyano group (-NCO) and carbamate group (-NH-COO-), so polyurethane adhesive shows a high degree of activity and polarity. It has excellent chemical adhesion with substrates containing active hydrogen, such as foam, plastic, wood, leath ...

Polydimethylsiloxane, (Polydimethylsiloxane), is a hydrophobic silicone material. It is used in various fields such as medicine, daily chemical products, food, construction, etc. Its derivatives have reached hundreds of kinds. The commonly used polysiloxanes are mainly: polydimethylsiloxane, cyclomethicone , Aminosiloxane, polymethylphenylsiloxane, polyether polysiloxane copolymer, etc. Among them, cyclomethicone is one of the commonly used polysiloxanes.Physical and chemical propertiesThe chemi ...

In the production of polyether modified silicone oil, various silicone surfactants with different properties can be obtained by modifying the number of silicone oil chain links or changing the ratio of polyether Eo and Po and changing the number of chain links and end groups. To meet the needs of a variety of industries. Good leveling, suitable for adding to a variety of resins (polyurethane resins, paint resins, plastic resins, etc.), which can well improve the intermolecular stress of these re ...

Silicone resin coatings are organic silicon resins or modified organic silicon resins as the main film-forming substances, which are elemental organic coatings, referred to as organic silicon coatings. Elemental organic coatings are the general term for coatings with elemental organic polymers as the main film-forming substances, including organic silicon, organic titanium, organic fluorine, organic aluminum, and organic zirconium coatings. Among them, the output of silicone resin coatings is th ...

In plastic compounding, a plastic additive that improves the interface performance of synthetic resins and inorganic fillers or reinforcing materials. Also known as surface modifier. It can reduce the viscosity of the synthetic resin melt in the plastic processing process, improve the dispersion of the filler to improve the processing performance, and then make the product obtain good surface quality and mechanical, thermal and electrical properties.The dosage is generally 0.5 to 2% of the fille ...

The application of silicone oil involves many fields, and it has been widely used in production, national defense, scientific research, and medical and health. It is mainly used for electrical insulation, demoulding, defoaming, damping and shockproof, hydraulic pressure, dustproof, waterproof box high and low temperature lubrication etc. However, in production and manufacturing, residual oil stains will be formed after the use of silicone oil, thus forming a process for cleaning silicone oil. Le ...

Textile softener classificationThe development history of textile softenerSilicone softener originated in the 1950s, and its development has gone through four stages.The first generation of silicone softener: the mechanical emulsification method is used to emulsify dimethyl silicone oil, but since the silicone oil itself does not contain active groups, it is not fast enough to bind to the fabric and is not washable. The effect of single use is not ideal, so it is rarely used as a softening agent ...

Silicone quaternary ammonium salts can be used in the hydrophilic finishing of fabrics, widely imparting good water absorption, sweat absorption, softness, smoothness, resilience, anti-static properties, and non-toxic and harmless to fabrics. It is a highly efficient, safe, multi- Functional soft finishing agent. In addition to being used for antibacterial and soft finishing of fabrics, silicone quaternary ammonium salts can also be used on the surface of other materials. For example, the approp ...

Silicone resin coatings can be divided into pure organic resin coatings and modified silicone resin coatings.Pure silicone paint is formed by dissolving pure silicone resin in xylene. It has good heat resistance, weather resistance, corrosion resistance, and insulation, but it has poor mechanical strength, adhesion and long drying time. But it can be modified with other resins to improve it. .Modified silicone resin coating is a coating with modified silicone resin as the film-forming substance, ...
