Historical Development
Taste the industry of chemical industry, changing with each passing day, and many wonderful products meet the world. Polythiol 309 is a product whose origin can be tested. At the beginning, the academic community studied for new quality, and after several years and repeated trials, it was the prototype. At that time, the process was not refined, the output was very small, and it was only tried in small fields.
However, over the years, the craftsmen were reluctant to study, improve the techniques, and optimize the process. As a result, its quality became purer and the quantity also increased. Since its inception, it has emerged in various fields and has a wider range of uses. From equipment manufacturing to fine chemicals, it all depends on its strength. Its development path is like a river on a boat. Although it encounters waves, it will go down the river, and the future will become brighter and brighter. It has gradually become a chemical treasure and is indispensable to the industry.

Preparation Method
The preparation of Polythiol 309 is related to the raw materials and production process, reaction steps and catalytic mechanism. The raw materials need to be selected from specific mercaptan compounds and matched with suitable additives. The production process first places the mercaptan compounds in a special reactor in proportion, precisely controls the temperature, and adds a catalyst under the protection of nitrogen to initiate the reaction. The reaction steps are gradual, and the temperature is slowly raised at the beginning to promote molecular activation. When a specific temperature is reached, the reaction intensifies. The reaction process is closely monitored and the conditions are fine-tuned according to the parameters. In the catalytic mechanism, the catalyst used has a unique activity check point, which can effectively reduce the reaction activation energy, accelerate molecular collision and binding, and improve the reaction rate and product purity. After this series of rigorous operations, high-quality Polythiol 309 can be prepared.

What are the characteristics of Polythiol 309?
Polymercaptan is a class of compounds containing multiple thiol groups (-SH). 309 should refer to photoinitiator 309, whose chemical name is 2-benzyl-2-dimethylamino-1- (4-morpholinophenyl) -1-butanone. Polymercaptan combined with 309 exhibits many unique properties.
In terms of reactivity, the mercapto group in polymercaptan has high reactivity. Under the action of photoinitiators such as 309, free radical reactions can occur rapidly when exposed to light, and the crosslinking and curing rate is extremely fast. This property is very useful in some fields that require strict curing efficiency, such as rapid prototyping, light curing coatings, etc.
In terms of the performance of the cured product, after the polymercaptan and 309 system are cured, the product has good flexibility. Because the polymercaptan structure can endow the polymer chain segment with certain flexibility, the cured product can be avoided from being too hard and brittle. At the same time, the system can also make the cured product have high hardness and wear resistance, which can effectively resist external friction and scratches, and is suitable for materials with high surface performance requirements.
In addition, the 309 photoinitiator is very sensitive to light, and can absorb light energy and generate active radicals in a wide spectral range, thereby initiating the curing reaction of the polymercaptan. In this way, even under relatively weak lighting conditions, effective curing can be achieved. In addition, the curing process of the system is relatively small in the degree of oxygen inhibition, which greatly enhances its adaptability in practical application environments, without the need to operate in harsh anaerobic environments.
In addition, polymercaptan is used with 309, and it is suitable for a wide range of substrates. Whether it is metal, plastic, or glass, it can achieve good adhesion and curing, which greatly expands its application scope and can play an important role in surface treatment and coating preparation of many different materials.

What are the advantages of Polythiol 309 over other similar products?
I heard your inquiry about the advantages of polymercaptan compared to other similar products. Polymercaptan is indeed unique in various applications.
First, the reactivity is extremely high. Just like a good horse, galloping on the way. When polymercaptan is matched with epoxy resins, it can make the curing reaction rapid and efficient. If other similar products are like slow walkers, polymercaptan is like a galloping horse, which can quickly solidify the material into shape in a short period of time, greatly shrinking the production time. This advantage is particularly prominent in projects with tight construction schedules.
Second, it is quite adaptable. No matter the climate is cold or warm, the environment is dry or wet, polymercaptan can show stable performance. Other products may fluctuate in performance due to changes in external conditions, but polymercaptan is like a needle of the sea, not disturbed by the environment. In humid places, it can also maintain a good curing effect, without the risk of bubbles or delamination, ensuring the quality and durability of the material.
Third, low toxicity and environmental protection. In today's world that focuses on health and ecology, this is the key. Other similar products may contain toxic ingredients, which are harmful to the human body and the environment. Polymercaptan is low toxicity, escorting the health of users, and also fits the general trend of environmental protection. It can be used with peace of mind in construction, decoration and other fields closely related to people.
Fourth, good flexibility. Like a flexible vine, it is not easy to break despite external force. The product after solidification of polymercaptan is not rigid and easy to fold, but has moderate flexibility, can resist vibration and deformation, and needs to withstand dynamic stress, such as bridges and roads. Repair materials can last for a long time and are not easy to crack and damage.

What are the usage methods and precautions of Polythiol 309?
The usage and precautions of polymercaptan and 309 are related to the fineness of workmanship. Polymercaptan is active and is often used as a curing agent. It is matched with epoxy resins, etc., which can speed up the curing process.
When using polymercaptan and 309, the first thing to do is to rematch the ratio. Weigh the two accurately to ensure that they meet the requirements of the formula. If the ratio is improper, the curing properties may not meet expectations, and the firmness and toughness may be affected.
Furthermore, the method of mixing is also necessary. It is advisable to stir slowly to make the two mix evenly. If the stirring is rapid, or air bubbles may enter, the surface of the product may be defective, and the internal structure may be uneven.
Temperature and humidity also have a loud noise for its use. If the temperature is high, the curing speed may be high, and the internal stress may be large, and the material is easy to crack; if the temperature is low, the curing will be slow, or it will be difficult to fully solidify. When the humidity is high, the water vapor may react with polymercaptan and 309, which will damage its chemical properties and cause poor quality.
In addition, the operator must be protected. Both may be irritating and can cause injury if they touch the skin or enter the eyes. Therefore, when wearing protective gear, such as gloves and goggles.
When storing, it should be placed in a cool and dry place to avoid heat and moisture and prevent its deterioration. When used, open it and seal it at full speed to avoid long-term contact with the air.
In short, the use of polymercaptan and 309, self-preparation, mixing, temperature and humidity control, to protection, storage, etc., must be carefully handled to obtain good results and ensure the quality of the workmanship.
