What are the physical and chemical properties of 3-Methacryloxypropyltrimethoxysilane
3-Methacryloxypropyltrimethoxysilane is one of the most important silicone coupling agents. Its physical properties are unique and interesting.
This substance is a colorless and transparent liquid under normal temperature and pressure, and it looks clear and pure without the slightest trace of impurities. Although its smell is not rich and pungent, it also has a special smell, which is slightly lingering. If you smell it carefully, you can feel its unique charm.
When it comes to the boiling point, it is about 255 ° C. When the temperature gradually rises, the substance is like a sublimated spirit, quietly transforming from liquid to gaseous, showing wonderful physical changes. In terms of melting point, the value is relatively low, about -50 ° C. In such a low temperature environment, it will gradually solidify from the flowing liquid, like a sleeping spirit, waiting for the temperature to rise, and then rejuvenate.
Its density is about 1.045 - 1.055g/cm ³, and when weighed in the hand, it can feel that its texture is moderate, not too heavy, nor is it light. Moreover, it has a certain solubility and can be miscible with many organic solvents, such as ethanol, acetone, etc., just like water emulsion, showing good affinity. However, its solubility in water is relatively limited. When it encounters water, it seems to maintain a subtle distance from water and can only be partially dispersed.
Furthermore, the flash point of this substance is about 108 ° C. This is a key safety indicator, warning that during storage and use, it is necessary to pay attention to temperature control, avoid approaching fire sources, and prevent accidental explosion accidents. It seems to guard a delicate boundary that cannot be easily crossed.
What are the precautions in storage and transportation of 3-Methacryloxypropyltrimethoxysilane?
3-Methacryloxypropyltrimethoxysilane, when storing and transporting, there are many things to pay attention to. This substance has certain chemical activity and should be stored in a cool, dry and well-ventilated place. Due to its sensitivity to moisture, moisture is easy to cause its hydrolysis, so be sure to avoid contact with water vapor. Storage containers should be tightly closed to prevent moisture intrusion.
When transporting, extra caution is also required. It should be ensured that its packaging is intact, free from vibration, collision and extrusion, to prevent the leakage of the substance due to package damage. And it needs to follow relevant transportation regulations and be classified as suitable dangerous goods for transportation.
Furthermore, this substance is irritating to a certain extent. If the temperature of the storage place is too high, or a chemical reaction is initiated, its stability will be affected. Therefore, the storage temperature should be controlled within an appropriate range, usually not higher than a specific temperature value.
During storage and transportation, the relevant operators should be aware of its characteristics and safety precautions, and be equipped with necessary protective equipment to prevent inadvertent contact and injury. If there is a leakage situation, it should be handled according to the established emergency response procedures to prevent the harm from expanding. In this way, the safety and stability of 3-methacryloxypropyltrimethoxysilane during storage and transportation must be ensured.
What are the safety precautions when using 3-Methacryloxypropyltrimethoxysilane?
3-Methacryloxypropyltrimethoxysilane is a commonly used silicone coupling agent. When using it, many protective measures are required to ensure safety.
First respiratory protection. Because of its volatility, it can cause respiratory discomfort in poorly ventilated areas or a large amount of volatile gases. Therefore, when operating in a well-ventilated place, if the ventilation conditions are limited, be sure to wear a self-priming filter gas mask (half mask) to filter out harmful gases in the air and protect the health of the respiratory tract.
Second, eye protection. If this substance is accidentally splashed into the eye, or hurts the eye tissue. During operation, chemical safety glasses should be worn to prevent accidental splashing and damage to the eyes.
The other is body protection. In order to avoid the substance from contacting the skin, anti-toxic substances must be worn during operation to penetrate the work clothes to isolate the skin from the outside world and reduce the risk of contact.
Hand protection is also indispensable. During operation, it is easy to touch the substance with both hands. Wear rubber oil-resistant gloves to prevent it from corroding and irritating the skin on the hand.
In addition, the operating environment should be kept away from fire and heat sources. Smoking is strictly prohibited in the workplace. Because the substance is flammable, it can cause combustion and explosion in case of open flames and hot topics. And the operation needs to be thoroughly cleaned. Do not eat, drink or smoke during work to prevent the entrance of harmful substances. If there is a leak, personnel should be quickly evacuated from the leak-contaminated area to a safe area and quarantined, strictly restricting access and cutting off fire sources. Emergency responders should wear self-contained positive pressure breathing apparatus and anti-virus clothing to cut off leakage sources as much as possible to prevent them from flowing into restricted spaces such as sewers and drainage ditches.
3-Methacryloxypropyltrimethoxysilane compatibility with other substances
3-Methacryloxypropyltrimethoxysilane, which is a commonly used type of silicone coupling agent. Its solubility with other substances is quite critical, and it is related to the effectiveness of many application scenarios.
In the organic polymer system, 3-methacryloxypropyltrimethoxysilane has good compatibility. Because one end has an organic functional group that can react with the polymer, that is, methacryloxy, it can be closely linked to polymers such as acrylates by radical polymerization; the trimethoxysilyl group at the other end can be hydrolyzed to form a silanol group, which can then be condensed with the hydroxyl group on the surface of inorganic substances. Therefore, it can build a bridge between organic polymers and inorganic fillers, improve the bonding force between the two, make the filler material disperse evenly, and enhance the properties of the composite material.
In the field of inorganic material surface treatment, it has excellent compatibility with most inorganic materials. The silanol group formed after the hydrolysis of trimethoxy silica group is easy to condensate with the hydroxyl group on the surface of inorganic materials such as glass, metal oxide, and ceramics, forming a strong chemical bond. A layer of organic functional coating is constructed on the surface of inorganic materials to improve the surface properties of inorganic materials, such as improving their lipophilicity and enhancing their affinity with organic phases.
However, in case of strong alkaline substances, the silica bonds of 3-methacryloxypropyltrimethoxysilane are vulnerable to attack and hydrolysis fracture, resulting in structural damage and poor solubility. And in extreme environments of high temperature, high humidity and no oxygen, the hydrolysis and condensation reaction may be excessive, resulting in insoluble cross-linking products, which affect the solubility and dispersion with other substances.
Overall, 3-methacryloxypropyltrimethoxysilane has good compatibility with many organic and inorganic substances. However, under specific conditions, it is also necessary to pay attention to the change of its solubility, and choose and use it reasonably to achieve the best application effect.
