Author:LongKom  Time:2013-7-16

Will we use it in our daily life? If it is possible to use in some chemical industry or more bar! Here is our silane coupling agent to tell you about its application in people's daily life! Please continue to browse below!

1. Plastic greenhouse industry: Silicone oil can be used as an internal additive in plastics to produce non-dripping film greenhouse to prevent fog and improve transmittance.
2. Used as fabric finishing agent: imported silicone oil plays a softening role. Silicone oil is especially suitable for underwear, sheets, towels and other finishing. It is not only soft, but also absorbent and sweaty, and comfortable to wear.
3. As leveling agent for paint and polyurethane slurry, dimethyl silicone oil can reduce the internal friction and stress of its molecules, thus playing the role of leveling and defoaming.
4. Used to make high-efficiency cutting fluid G-747, high-grade cleaning agent.
5. KE-45-T is used as foaming homogenizer in rigid polyurethane foam system to make the cell fine and uniform.
6. The cosmetics industry is used to make cream products, which chemically lubricate the skin, moisturize and resist wrinkles.
7. The pesticide industry is used as a wetting agent of glyphosate to improve its efficacy and reduce public hazards.

8. It is the key component of self-emulsifying defoamer and delayed coking defoamer in refining industry.

Mechanical Properties of Silicone Resin
The mechanical strength (bending, tension, impact and abrasion resistance) of silicone resin is weak.

When used as coatings: mechanical properties of imported silicone resin are mainly more important than hardness, flexibility, thermoplasticity and cohesiveness.

Hardness and Flexibility: Silane Coupling Agent Chemical Silicone Resin Structure (Crosslinking Degree and Groups); Pigment and Catalyst; Compound of Silicone Resin; Organic Resin Modification.

Bonding property: good for iron, aluminium, silver and other metals as well as glass, ceramics, etc. without treatment. But the adhesion to copper is not very good, especially at high temperature. For organic materials such as plastics and rubber, they depend on their surface energy and compatibility.

Introduction of Common Types and Properties of Silicone Mould Removal Agents

Organosilicon release agent food grade PET release agent can be divided into many kinds according to the different raw materials used. The following is a brief analysis of its performance by enumerating several kinds of organic silicon release agent.

1. Dimethyl silicone oil

KM-742T demoulding agent can dissolve with benzene, toluene, xylene, ether and so on. KF-96-1000cs can dissolve in a small amount in ethanol, butanol, propanol, insoluble in liquids such as cyclohexane, methanol, vegetable oil, water and paraffin oil. The release agent of this material is non-toxic. KF-965-1000cs dimethyl silicone oil has good resistance to high temperature. Its viscosity will not change with temperature. It has good electrical properties and hydrophobicity. It is a kind of commonly used release agent, such as rubber tire, hose, belt and triangle belt.

2. Methyl phenyl silicone oil

G-747 is a kind of oily liquid with no color or yellowish color. Its physical properties vary with its composition and molecular weight. It not only has the common characteristics of dimethyl silicone oil, but also has strong resistance to high temperature and radiation. KE-45-T has a lower temperature-viscosity coefficient than dimethyl silicone oil.

3. Diethyl Silicone Oil

It is a transparent liquid with no color or light yellow color. It has low coefficient of resistance to high temperature viscosity. Silane coupling agent has good lubrication and dielectric properties. It has no toxicity and decay erosion characteristics. It can dissolve in toluene, ether, chloroform and other organic solvents.

4. Emulsified silicone oil
Chemical emulsified silicone oil is a polymethylsiloxane emulsifier. 
In addition, the types of silicone release agents include methyl vinyl silicone rubber, methyl block greenhouse vulcanized silicone rubber, methyl silicone resin and so on, which have good properties.
