The storage conditions of diaminohydroxyl (diaminohydroxyl) solution are related to the stability and utility of the substance, which cannot be ignored.
First, it needs to be stored in a cool place away from light. This is because diaminohydroxyl (diaminohydroxyl) is mostly sensitive to light and heat, and light and high temperature can easily promote its chemical reaction and cause it to deteriorate. If exposed to hot sun or high temperature environment, its molecular structure may be damaged, which will affect its performance. Therefore, it should be placed in a cool and difficult-to-reach place. If possible, it can be placed in a dark room or a container with a light-shielding device.
Second, humidity control is also key. High humidity environment is easy to make diaminohydroxyl (diaminohydroxyl) absorb moisture, or cause moisture, or cause hydrolysis, or cause hydrolysis. Once hydrolysis occurs, the chemical properties of the substance will change and the activity will be reduced. It is suitable for the storage place to be dry, and a desiccant can be placed in the storage container to ensure the dryness of the environment.
Third, the choice of storage containers should also be particular. Materials with stable chemical properties and no reaction with diaminohydroxyl groups (diaminohydroxyl groups) should be selected. Glass containers are usually preferred because of their good chemical stability and easy observation of internal conditions. However, if the substance has a special reaction to the glass composition, it is necessary to choose a suitable plastic or metal container, and make sure that the container is well sealed to prevent contact with outside air.
Fourth, keep away from fire sources and strong oxidants. Diamine (diaminohydroxyl) or flammable, easy to cause fire in case of fire; and strong oxidants can react violently with diaminohydroxyl (diaminohydroxyl), or cause explosion and other hazards. Therefore, fireworks are strictly prohibited in the storage area, and they are placed separately from strong oxidants to ensure safety.

Diaminosilicone oil is one of the silicone products. It is widely used. However, many safety matters must be paid attention to when using it to ensure the safety of people and the environment. The following are detailed:
First, it is related to storage. Diaminosilicone oil should be stored in a cool, dry and well-ventilated place, away from fire and heat sources, and protected from direct sunlight. Because of its flammability, there is a risk of combustion and explosion in case of open flame, hot topic or oxidant. The storage temperature should be controlled at 5 ° C - 35 ° C. If the temperature is too high or too low, it may affect the quality of the product. And the storage container must be tightly sealed to prevent moisture and impurities from invading and causing product deterioration.
Second, it involves the use process. When operating, be sure to ensure that the ventilation conditions are good, and the best choice is to do it in a fume hood. Because the vapor evaporated by diaminosilicone oil may irritate the respiratory tract and eyes, if inhaled in excess, it may cause damage to the human body. Operators should wear appropriate protective equipment, such as protective glasses, masks and gloves. Avoid direct contact between the skin and the eyes of the product. If it comes into contact accidentally, rinse it with a lot of water immediately and seek medical treatment in time.
Third, pay attention to product compatibility. Diaminosilicone oil should not be mixed with strong oxidants, strong acids, strong alkalis and other substances to avoid chemical reactions and cause danger. Before using it with other chemicals, be sure to conduct a small test to confirm its compatibility before large-scale application.
Fourth, pay attention to waste disposal. After use, the remaining products and waste packaging must not be discarded at will. It should be properly disposed of in accordance with local environmental regulations and usually handed over to a professional recycling agency to avoid pollution to the environment.
In short, when using diaminosilicone oil, it is necessary to strictly follow the safety operation procedures and pay attention to every detail, so as to not only exert its excellent performance, but also ensure safety and the environment from harm.

The solution of diaminohydroxyl groups has a wide range of concentration specifications, depending on different uses and needs.
In many experimental and industrial processes, the common concentration specifications are as follows: low concentration, or between 0.1% - 1%, this concentration is often used in fine chemical reactions, and the proportion of reactants needs to be precisely controlled. Because the reaction is more sensitive, low concentration can ensure that the reaction is mild and orderly, and avoid violent reactions that cause impure products.
In the concentration, it is probably in the range of 1% - 10%. Such concentrations are widely used, such as surface modification treatment of some materials. Moderate concentrations can effectively graft diaminohydroxyl groups on the surface of the material, improve the hydrophilicity and adhesion of the material, and do not overly change the original properties of the material.
High concentrations, or 10% - 50% or even higher. This is more common in specific synthesis processes, which require a large number of the group to participate in the reaction to quickly generate the target product. However, high concentrations also carry risks, such as too fast reaction rate and reduced system stability. Therefore, careful control of reaction conditions is required during operation. < Br >
There are also customized concentration specifications, which are specially prepared according to special scientific research projects or industrial production requirements, or very low concentrations of micro-doping, only ppm level, to achieve unique functions; or very high concentrations close to saturation state, for special concentration, crystallization and other processes. In short, the concentration specifications of diaminohydroxyl group solutions are rich and diverse to suit the needs of different fields and scenarios.

During the use of diaminosilicone oil and its solution, it is necessary to pay attention to many operation points to ensure that its effect can be well exerted.
First, observe carefully before use. It is necessary to carefully examine the appearance of diaminosilicone oil solution to see if it has the appearance of precipitation and stratification. If there is such a situation, it is very likely that the quality of the product has changed, or it is caused by improper storage. At this time, it should be handled with caution and must not be used rashly. Furthermore, it is necessary to accurately determine the concentration of the solution, and adjust the concentration to an appropriate level according to the specific use requirements and process standards. If the concentration is too high, it may cause the product to feel greasy, affecting the final quality; if the concentration is too low, the expected treatment effect may not be achieved.
Second, stir at a constant speed. When using, stirring should be maintained at a uniform speed. This is due to the characteristics of diaminosilicone oil itself. If the stirring speed is too fast, it is easy to produce foam, and the existence of foam will interfere with the treatment process and affect the uniformity; if the stirring is too slow, it is difficult to ensure that the components in the solution are fully mixed, resulting in uneven treatment effects. Therefore, it is crucial to maintain a suitable and stable stirring speed.
Third, the temperature needs to be controlled. Temperature has a significant impact on the performance of diaminosilicone oil solutions. If the temperature is too high, the silicone oil may degrade, destroying its molecular structure, thereby weakening its function; if the temperature is too low, the fluidity of the solution will become poor, which is not conducive to uniform coating or penetration, which will also affect the treatment effect. Therefore, it is necessary to strictly control the temperature within the appropriate range according to the product instructions during use.
Fourth, avoid long-term exposure and mixed storage. Diaminosilicone solution should not be exposed to the air for a long time to prevent it from reacting with some components in the air and causing performance changes. At the same time, it should not be stored or used in combination with other chemicals at will to avoid chemical reactions, generate harmful substances, or reduce the efficacy of diaminosilicone oil.
Fifth, the operation should be standardized. When using, the operator should follow the standard process and wear necessary protective equipment, such as gloves, masks, etc., to prevent the solution from contacting the skin or inhaling the human body, causing damage to health.
